Research and Organise
Combine web information, uploaded files, Project instructions and related chats to create a controlled working context.
Build and Iterate
Turn an idea into a document, diagram, visualisation, prototype, interactive tool or shareable Artifact, then refine it in place.
Code and Complete Work
Move into Claude Code for software engineering or Cowork for longer, connected and multi-step knowledge work.
GP
Use the Cheat Sheet
The best Claude workflow separates context, judgement and output
Give Claude the right evidence and boundaries, keep important decisions under human review, then ask for a deliverable designed for its real destination. That discipline matters for reliable SEO content writing, client research and technical work.
Claude Cheat Sheet
Match the Task to the Right Claude Capability
Do not begin every job in a blank chat. Use this map to choose the feature, give it the right starting context and apply the most important quality check.
| Your task | Best starting point | Give Claude | Check before using |
|---|---|---|---|
| Ask, write or edit | Chat | A clear outcome, audience, context and format | Accuracy, tone and unsupported assumptions |
| Solve a difficult problem | Extended thinking | Decision criteria, constraints and known evidence | Whether the reasoning addresses the real objective |
| Find current information | Web search | Market, date range, source preferences and exclusions | Publisher, date, claim support and context |
| Produce a research report | Research | A decision-led brief and expected evidence types | Coverage, citations, conflicts and missing viewpoints |
| Maintain recurring context | Projects | Persistent instructions, selected files and purpose | Source freshness, duplication and instruction drift |
| Create a reusable output | Artifacts | The user, desired interaction and acceptance criteria | Function, accessibility, content and sharing settings |
| Work on software | Claude Code | Repository context, task scope and verification commands | Diff, tests, security and unintended changes |
| Delegate knowledge work | Cowork | A goal, approved tools, file boundaries and checkpoints | Actions taken, output quality and sensitive data |
Core Reasoning Modes
Use Chat for Iteration and Extended Thinking for Harder Decisions
Longer reasoning is not automatically better. Standard Chat is usually the fastest route for clear drafting, explanation and revision. Extended thinking becomes more useful when the problem has interacting constraints, several plausible paths or a high cost of missing an important step.
Standard Chat
Use a normal conversation when you need speed, iteration and a direct response rather than a lengthy investigation.
- Draft and refine content in several focused passes.
- Ask for critique before requesting the rewrite.
- Keep one clear objective per conversation thread.
- Give examples when voice or format matters.
Extended Thinking
Use deeper reasoning for complex analysis, technical planning, difficult comparisons and decisions with competing requirements.
- Define what a successful answer must accomplish.
- Separate hard constraints from preferences.
- Ask Claude to identify uncertainty and failure modes.
- Review the result against the original criteria.
Memory and Chat Search
Use memory and conversation search to recover useful context, while keeping durable client rules and source material inside the appropriate Project.
- Treat remembered context as a convenience, not evidence.
- Confirm sensitive preferences before acting on them.
- Use Project instructions for repeatable work standards.
- Remove stale context when a process changes.
Begin With the Outcome
State what you need to decide, create or change. A strong goal is more useful than a vague request for something “good” or “professional”.
Supply Relevant Context
Add the audience, market, existing material, constraints and examples that genuinely affect the answer.
Define the Quality Standard
Describe what must be accurate, original, usable, compliant or consistent—and what the response must avoid.
Name the Destination Format
Specify whether the result will become a webpage, email, report, spreadsheet, code change, brief or client recommendation.
Build in a Review Pass
Ask Claude to check the finished work against the brief, then perform the factual and professional review yourself.
Current Information and Evidence
Choose Web Search for Current Facts and Research for Broader Investigation
Both capabilities bring external information into Claude, but they serve different depths of work. Web search is suited to a focused current question. Research is designed to explore several angles, run multiple searches and synthesise a longer evidence-backed result.
Web Search
Use web search when a useful response depends on recent, changing or externally verifiable information.
- State the location and date range where relevant.
- Request first-party or primary sources for key claims.
- Open the citations rather than trusting their presence.
- Use follow-up searches to resolve contradictions.
Research
Use Research when the deliverable needs broader discovery, several search paths, comparison and a structured report.
- Frame the decision the report must support.
- Identify essential evidence types and exclusions.
- Ask for disagreement, limitations and missing data.
- Separate sourced facts from Claude's interpretation.
Define the Decision
Explain what the research will influence and what a useful answer must clarify.
Set the Evidence Rules
Name preferred source types, markets, dates, exclusions and comparison criteria.
Audit the Citations
Check that important statements are supported by the cited page in its original context.
Record Gaps and Action
Preserve uncertainty, missing evidence and the next step alongside the conclusion.
SRC
Compare the Perplexity Playbook
Citations reduce verification friction; they do not replace verification
For SEO, GEO, publishing and client advice, inspect source authority, recency, methodology and exact claim support. This same discipline strengthens practical answer engine optimisation and generative engine optimisation.
Reusable Context
Use Claude Projects for Work That Should Not Start From Zero
A Project is a self-contained workspace with its own chats, instructions and knowledge. It is useful when several tasks share the same client, topic, product, evidence base or editorial rules—but it still needs deliberate maintenance to remain accurate.
Project Instructions
Define the purpose, audience, tone, recurring workflow, quality checks and exclusions that should guide every relevant conversation.
Read the official Projects guideProject Knowledge
Upload only useful, current material. Name files clearly, remove superseded versions and distinguish source evidence from working drafts.
Use the Project blueprintProject Chats
Use separate chats for research, planning, drafting, review and implementation so each thread remains understandable and easy to revisit.
Turn work into an ArtifactGive the Project One Durable Purpose
Good boundaries include one client, website, product, campaign, publication or recurring research programme.
Upload Canonical Material
Prioritise approved brand guidance, product facts, research, templates and current reference material over a large untidy archive.
Separate Work Into Clear Chats
Keep discovery, content briefs, drafts, technical analysis and final review in distinct threads with descriptive titles.
Review the Knowledge Base
Remove stale facts, duplicate files and old instructions before they silently affect future outputs.
Build Beside the Conversation
Use Claude Artifacts When the Output Should Be Edited, Used or Shared
An Artifact places substantial standalone content in a dedicated workspace beside the chat. Instead of burying the deliverable inside a long conversation, you can iterate on a document, visualisation, code asset, prototype or interactive experience as its own object.
Documents
Create reports, plans, briefs, guides and polished content that needs focused revision outside the main chat stream.
Visuals and Diagrams
Build charts, diagrams, SVG assets and explanatory visuals when structure or relationships are clearer on screen.
Apps and Tools
Describe a calculator, simulator, dashboard, quiz or utility, then test and refine the interaction with Claude.
Interfaces and Code
Create website concepts, components and working prototypes before moving production engineering into a proper code workflow.
| Use | Keep it in Chat when | Create an Artifact when | Final check |
|---|---|---|---|
| Explanation | You need a short answer or discussion | The explanation should become a reusable guide | Facts, clarity and audience fit |
| Writing | You are exploring ideas or reviewing a passage | You need a substantial document to revise | Voice, originality and publishing requirements |
| Visualisation | A simple textual description is sufficient | The relationship needs a chart, diagram or interface | Labels, values, accessibility and interpretation |
| Prototype | You are discussing requirements and options | You want to test a working interaction | Behaviour, edge cases, privacy and hand-off |
BLD
Read the Artifacts Guide
Describe the user and behaviour, not only the appearance
A stronger Artifact brief states who will use it, what they need to accomplish, what inputs and outputs exist, how errors should behave and what a successful result looks like. Treat generated code as a prototype until it has been reviewed and tested.
Practical Claude Workflows
Treat Claude as a Controlled Workflow, Not a One-Shot Generator
The strongest results usually come from a sequence of small, reviewable stages. Separate discovery from judgement, drafting from critique and creation from verification so that an early mistake does not quietly shape the whole deliverable.
01
Discover
Gather the Right Context
Collect the brief, source material, current facts, existing work and constraints that genuinely affect the result.
Clean evidence pack02

Map the Decision or Deliverable
Ask Claude to propose the structure, identify unknowns and explain how the result will meet the acceptance criteria.
Reviewable plan03
Create
Produce the First Useful Version
Generate the draft, analysis, file, Artifact or code change from the approved plan rather than from a vague opening prompt.
Working version04
Critique
Look for Weakness Before Rewriting
Request a gap analysis against the brief. Identify unsupported claims, repetition, edge cases and missing perspectives first.
Prioritised issue list05
Verify
Check Facts, Function and Fit
Validate important claims at source, inspect calculations, run tests and confirm that the output suits its real audience.
Evidence-backed result06
Package
Prepare the Final Destination
Convert the approved work into the webpage, report, presentation, spreadsheet, file, pull request or client hand-off required.
Usable deliverable
QA
Run the SEO Checker
Do not ask the same Claude pass to create, approve and verify itself
Use a separate critique step and keep high-impact judgement with a human. For website work, combine Claude's analysis with a structured SEO audit and real performance data.
SEO, Content and Guest Posting
Six Claude Workflows That Support Real SEO Decisions
Claude is most useful when it organises evidence, challenges a weak assumption or improves a controlled deliverable. It should support keyword, content and outreach decisions—not manufacture strategy without search data, business context or editorial judgement.
KW
Keyword BriefIntent before wording
Turn Keyword Data Into a Search-Intent Brief
Give Claude an exported keyword cluster, current ranking URLs and the business offer. Ask it to separate intents, identify the dominant page type and recommend one primary purpose for the target URL.
- Input: measured keyword data
- Output: intent-led brief
- Check: SERP reality
- Avoid: invented volumes
GAP
Content GapEvidence over volume
Compare Competitor Coverage Without Copying It
Supply extracted headings, claims and source types from relevant pages. Ask Claude to map shared coverage, missing questions, weak evidence and opportunities for original experience or first-party insight.
- Input: competitor evidence
- Output: opportunity map
- Check: unique value
- Avoid: stitched outlines
BRF
Content BriefOne URL, one purpose
Build a Brief Around the Reader's Next Decision
Define the target reader, query stage, primary action, evidence needs and internal-link destinations. Let Claude organise the brief, then remove anything added only because competitors mentioned it.
- Input: intent and audience
- Output: production brief
- Check: task completion
- Avoid: heading inflation
REF
Content RefreshPreserve what works
Refresh an Existing Page From a Change List
Provide the live copy, query data and a dated list of factual or strategic changes. Ask Claude for a section-level delta before rewriting so rankings, useful passages and established internal links are not lost casually.
- Input: page and change data
- Output: controlled update
- Check: retained strengths
- Avoid: full rewrite first
INT
Internal LinksContext before anchor
Map Relevant Links Without Forcing Anchors
Give Claude a current URL list with each page's purpose. Ask it to match genuine reader needs to relevant destinations, suggest natural anchor variations and flag links that would interrupt the paragraph.
- Input: approved URL map
- Output: link suggestions
- Check: destination fit
- Avoid: exact-match repetition
GP
Guest PostPublication-first writing
Develop a Natural Guest Post Around Publisher Fit
Start with the publication, its readers and editorial style. Use Claude to shape a useful article, review promotional tone and test whether each backlink belongs naturally in the surrounding argument.
- Input: publisher context
- Output: editorial draft
- Check: link naturalness
- Avoid: brand-led outline
| Workflow stage | Claude should do | Your data should provide | Human approval |
|---|---|---|---|
| Research | Organise, compare and expose gaps | Keywords, pages, sources and dated facts | Source quality and search-intent judgement |
| Strategy | Test scenarios and structure options | Business goals, audience and constraints | Priority, trade-offs and resource allocation |
| Creation | Draft from an approved plan | Examples, evidence, voice and destination | Originality, accuracy and editorial value |
| Optimisation | Identify specific improvements | Performance data and current page state | Whether each change helps the reader |
| Reporting | Explain patterns and package findings | Verified metrics and agreed definitions | Claims, implications and client advice |
Documents, Spreadsheets and Data
Use Claude to Analyse Source Files and Produce Real Deliverables
Claude can work with uploaded material and create downloadable documents, spreadsheets, presentations and PDFs. The important distinction is between generating a file and producing a trustworthy business asset: the latter still needs source control, calculation checks and visual review.
Documents
Create briefs, reports, proposals and editable working documents with a clear audience and approval state.
Spreadsheets
Structure tables, calculate fields, clean data and create analysis that can be inspected cell by cell.
Presentations
Turn an approved narrative into a concise slide sequence with useful evidence and a clear next action.
PDF Outputs
Package stable reports and hand-offs only after checking page flow, labels, links and visual rendering.
Separate Source Files From Working Files
Keep originals unchanged. Label transformed data, drafts and approved outputs clearly so Claude does not treat an old derivative as the authoritative source.
Describe the Data Before Asking for Analysis
Define each field, unit, date period, missing-value rule and important exclusion. A neat spreadsheet can still encode the wrong meaning.
Make Calculations Inspectable
Request formulas, assumptions and intermediate values where possible. Spot-check totals and edge cases independently before using the result.
Render and Review the Final File
Check tables, charts, page breaks, text overflow and mobile or print legibility. Correct data can still be presented misleadingly.
Keep a Version Trail
Record what changed, which source version was used and who approved the final deliverable so the work can be reproduced later.
Agentic Software Engineering
Use Claude Code When the Work Lives Across a Real Codebase
Chat can explain a snippet, but Claude Code is designed to understand a repository, edit files, run commands and work alongside development tools. Its value increases with clear scope, repository guidance and verification commands—not with permission to change everything at once.
Ask for a Codebase Map First
Identify relevant directories, dependencies, data flow, conventions and likely test locations before authorising implementation.
Review the Proposed Change Set
Request the files likely to change, expected behaviour, risks and verification plan. Narrow the scope before coding begins.
Implement in Small, Coherent Steps
Prefer focused edits that can be understood and tested. Avoid mixing a feature, refactor and unrelated cleanup in one pass.
Run the Repository's Real Checks
Use the project's tests, linting, type checks and build commands. Add targeted tests for the behaviour that changed.
Review the Diff and Remaining Risk
Inspect every changed file, check for secrets or unintended edits and record what was not verified before merging or deploying.
Debug Across Files
Trace symptoms through dependencies, reproduce the issue and fix the underlying behaviour.
Implement Features
Turn an approved specification into code, tests and a reviewable change set.
Refactor Carefully
Improve structure while using tests and diffs to protect existing behaviour.
Review and Explain
Map unfamiliar code, examine pull requests and surface risk before implementation.
SAFE
Explore Claude Code
Repository access is capability, not approval
Keep permissions narrow, review commands that affect external systems and never treat a passing test suite as proof that security, privacy or business behaviour is correct. Human review remains essential.
Agentic Knowledge Work
Use Claude Cowork for Multi-Step Work Across Files, Tools and Apps
Cowork is designed for longer knowledge-work tasks such as research, analysis, document creation and file organisation. You define the outcome and the permitted working environment; Claude plans and carries out the stages. That extra capability makes access boundaries and checkpoints more important.
| Workspace | Best used for | Typical scope | Your control point |
|---|---|---|---|
| Claude Chat | Conversation, drafting, explanation and focused analysis | One interactive thread | Prompt, follow-up and response review |
| Claude Cowork | Research, analysis, documents and multi-step knowledge work | Files, tools, apps and longer tasks | Access, boundaries, checkpoints and action review |
| Claude Code | Software engineering, debugging, testing and repository work | Codebase, terminal and development tools | Repository scope, commands, diff and tests |
Define a Verifiable Outcome
Describe the finished result, the audience, required files and how you will determine whether the task succeeded.
Grant Only Relevant Access
Choose the smallest set of folders, tools, connectors and accounts required for the specific job.
Set Action Boundaries
State what Claude may read, create or change and which external or irreversible actions require approval.
Use Meaningful Checkpoints
Review the plan, sample output and proposed actions before the task scales across many files or systems.
Inspect What Changed
Check created and modified files, tool actions, sources and unresolved issues before accepting the result.
RISK
Use Cowork Safely
Capability and exposure increase together
A Cowork session can work with real files, web information, code and connected apps. Review what it can access as carefully as what you ask it to do, especially when client, financial, account or unpublished business data is involved.
Reusable Methods and Connected Context
Skills Teach the Method; Connectors Provide Access; Plugins Package Capabilities
These layers solve different problems. Use Skills to make a specialist workflow repeatable, connectors to give Claude controlled access to external information or actions, and plugins when a packaged extension combines several capabilities.
Skills
Give Claude specialist instructions, reference knowledge and a reliable process for recurring work such as brand checks, reports, file creation or editorial review.

Shortcuts That Preserve Quality
Eight Claude Time-Savers for Faster, Cleaner Work
The best shortcut removes repeated setup or unnecessary rewriting. It should not remove the evidence, review or approval step that makes the final work trustworthy.
Save Durable Rules in Projects
Stop repasting stable audience, tone, source and workflow guidance into every chat.
Ask for a Delta First
Before rewriting, request only what is outdated, weak, missing or inconsistent.
Approve the Outline Early
Correct direction and scope before Claude invests effort in a finished deliverable.
Separate Facts From Inference
Ask for sourced findings, interpretation and recommendation under distinct labels.
Critique Before Revision
Create a prioritised issue list, approve it, then rewrite only the affected areas.
Prototype With an Artifact
Test structure and interaction beside the chat before engineering the final version.
Use Samples Before Scale
Review a few rows, pages or files before applying the same operation everywhere.
End With a Change Log
Ask Claude to list edits, evidence, passed checks and unresolved uncertainty.

Build With Claude
Use the Claude API When the Model Must Sit Inside Your Product or Process
A Claude chat subscription serves a person using Claude's interfaces. The API is a separate, usage-billed route for software, automations, agents and internal systems that call Claude programmatically.
Design the workload before choosing the model
Estimate the volume, input size, expected output, latency target and failure cost. Then choose the lowest-cost model that passes a representative evaluation set.
- Separate interactive, batch and high-stakes tasks.
- Set output limits and stop unnecessary verbosity.
- Use prompt caching where repeated context qualifies.
- Log quality, latency, token use and failure reasons.
- Keep human approval for material external actions.
Route by Task Difficulty
Use Haiku or Sonnet for well-defined work and escalate only the tasks that genuinely need deeper capability.
Control Context Size
Retrieve the most relevant evidence instead of sending an undifferentiated archive with every request.
Cache Stable Prefixes
Repeated instructions or reference material may be cheaper when the request is structured for prompt caching.
Batch Non-Urgent Work
Use batch processing when a job does not need an immediate interactive response and the feature fits the workload.
Cap the Output
Define the required format and maximum length so the model does not spend tokens producing material nobody will use.
Evaluate Before Scaling
Test accuracy, completeness, style and refusal behaviour on real examples before sending production volume.
Failure Patterns
Eight Claude Mistakes That Waste Time or Reduce Trust
Most poor results are not solved by requesting a longer answer. They improve when the task, evidence, workspace, permissions and acceptance checks are designed more carefully.
Starting Every Job in a Blank Chat
Use a Project when stable knowledge, instructions and related conversations should persist.
Choosing a Model by Reputation
Test the actual work. A faster, cheaper model may pass the same acceptance standard.
Uploading an Unfiltered Archive
Too much irrelevant context can obscure the evidence Claude genuinely needs.
Publishing a One-Shot Draft
Separate outline, evidence, draft, critique and final review into controlled passes.
Trusting Citations by Appearance
Open the source and confirm the publisher, date, claim support and surrounding context.
Skipping the Diff or Tests
For code and files, inspect what changed and run meaningful verification before acceptance.
Granting Excessive Access
Give Cowork, Code, connectors and plugins the smallest relevant permission surface.
Losing Output Ownership
Name the destination, version, approver and next action so a useful result does not disappear in chat.

Sonnet is the sensible production starting point for many tasks. Move to Opus or Fable when tests show a material capability gap, or to Haiku when a well-defined task prioritises latency and cost.
Is Claude better than ChatGPT?
Neither is better for every job. Claude is a strong fit for long-context analysis, writing, Artifacts, coding and connected work surfaces; ChatGPT may be preferable when its broader tool and multimodal ecosystem better matches the task. Compare them on your real workflow.
What is the difference between Projects and Artifacts?
A Project is a persistent workspace for related chats, instructions and knowledge. An Artifact is a substantial output—such as a document, visualisation, prototype or tool—that can be edited and used beside the conversation.
What is Claude Code?
Claude Code is Anthropic's agentic coding environment for understanding repositories, editing code, running commands and supporting development work. Review its plan, changes, tests and security implications like any engineering contribution.
What is Claude Cowork?
Cowork is a work-oriented surface for longer, multi-step knowledge tasks involving research, files and connected tools. Give it narrow access, explicit boundaries, review checkpoints and approval requirements.
Can Claude search the web?
Claude can use web search and Research features where available. Treat citations as leads to inspect: check the source, date, evidence and whether the cited page actually supports the claim.
Does a Claude subscription include API credits?
No. Claude chat subscriptions and Claude API billing are separate. API use is metered according to the developer pricing and any relevant platform features.
Can Claude create Word, Excel, PowerPoint and PDF files?
Claude can create and edit supported documents and other files in relevant product experiences. Always open the result and review formatting, formulas, citations, accessibility and business accuracy before delivery.
Is Claude useful for SEO?
Yes, especially for research synthesis, content briefs, comparisons, editorial critique, structured data work and code support. It should complement first-party evidence, specialist judgement and a disciplined SEO content process.
Should I put confidential client data into Claude?
Only when the account, contract, organisational policy and task permit it. Minimise the data shared, understand retention and training terms, restrict tool access and avoid exposing secrets that are not required.
