WordPress documentation site
Document to save time during every intervention
When a WordPress site evolves, maintenance quickly becomes a series of repetitive actions: updates, checks, fixes, optimization, content requests, design changes, SEO adjustments, etc. Without documentation, every simple task turns into an investigation: where is the cache configured, which child theme is active, why was this plugin installed, who has access to hosting, what was the reasoning behind that redirect, or what procedure should be followed to restore a backup.
Good documentation is not a pile of theoretical pages. It is a practical system that enables any contributor (you, a service provider, a colleague, your future self) to understand the site’s architecture, reproduce actions with confidence, limit errors, and reduce intervention time. The objective is simple: transform maintenance into a controlled, traceable, and predictable process.
Start with a site profile sheet
The first building block is a single page that summarizes the essential information. It should be readable in under two minutes and provide the basic reference points. Ideally, it contains:
• Site URL (and any secondary domains) + environment (production, pre-production, staging).
• CMS and current version (WordPress) + PHP version + MySQL\/MariaDB version (if you know it).
• Active theme, child theme (yes\/no), and link to the Git repository if you have one.
• Short list of critical plugins (security, cache, forms, e-commerce, SEO) and their role.
• Hosting provider contact details, control panel location (cPanel, Plesk, custom console), and server name if relevant.
• Contacts and responsibilities: who approves what, who works on the site, who manages DNS, who manages emails.
This identity sheet serves as a point of entry: when an incident occurs, you immediately know where to look, whom to contact, and what the technical context is.
Map access and permissions (without exposing secrets)
WordPress maintenance involves several layers of access: WordPress administrator account, FTP\/SFTP, database, hosting, DNS, CDN, backup tool, potentially payment gateway, SMTP, etc. Documenting who has access to what is often more important than documenting how it works.
A few best practices:
• Never put passwords in plain text in the documentation. Instead, note the location of the vault (password manager) and the naming convention for entries.
• Document roles: WP administrator, editor, author, restricted access to certain plugins, etc.
• Specify the onboarding\/offboarding procedure: how to create access, how to remove it, and what checks to perform after a provider leaves.
• Indicate access paths: login URL \/wp-admin, hosting panel URL, DNS console, etc., without adding other links if you centralize them elsewhere.
Describe the technical architecture and dependencies
A WordPress site is rarely just WordPress. It relies on a combination of components: theme, plugins, snippets, integrations, and external services. Useful documentation explains the dependencies and potential points of fragility.
Theme, child theme, and customizations

List: the theme name, whether a child theme exists, and where the customizations are located (functions.php, overridden template files, additional CSS, hooks). Also mention whether changes have been made directly to a parent theme (not recommended, but it happens) to prevent losses during updates.
Critical plugins and their functional role
Don’t document just a list. Explain why: this plugin is used for caching, this one handles redirects, that one adds fields, etc. Add notes such as: Do not disable: impact on payment, Dependency: this plugin requires such-and-such extension, Alternative if it is removed.
External integrations
Forms (where emails arrive), analytics, tag manager, booking tools, CRM, newsletter, payment, reCAPTCHA, APIs, webhooks: note what is connected, where the keys are located (in the vault), and which person/team manages the third-party service.
Document update procedures (and contingency plans)
The most valuable documentation is the kind that prevents incidents during updates. Write a simple, sequenced procedure that describes the order and the checks to perform. For example:
• Step 1: create a restore point (files + database backup).
• Step 2: update non-critical plugins (then test key pages).
• Step 3: update critical plugins (payment, forms, cache) one at a time (then test).
• Step 4: update the theme (and check for front-end regressions).
• Step 5: update WordPress (and test again).
• Step 6: check logs/errors, performance, cron jobs, and emails.
• Step 7: document what was updated and archive the versions.
Add a section if things go wrong: how to disable a plugin via FTP, how to restore a backup, and how to revert to an earlier version if you have a rollback strategy. If you encounter recurring blockers, rely on a dedicated resource such as this practical guide for responding when an update goes wrong to align your intervention reflexes and diagnostic steps.
Track the history of changes (operational changelog)
A changelog is not just for developers. Even for a brochure website, keeping a changelog makes maintenance easier: you know what changed, when, why, and by whom. This log can be minimal:
• Date
• Author/Contributor
• Change (plugin added/removed, setting changed, redirects, structural content)
• Expected impact
• Tests performed
• Internal link to the ticket/brief if you have one
Its value becomes especially apparent in the event of a bug: if an issue has occurred since yesterday, you can immediately review the changes from the previous day and drastically reduce diagnostic time.
Standardize routine tests with a checklist
Documenting isn’t just about writing. It’s also about turning your maintenance into a verifiable routine. A short, repeatable checklist helps avoid forgetting critical points. Example of tests after an update or intervention:
• Front end: homepage, contact page, service page, internal search, menus, responsive behavior.
• Forms: submission + email receipt + anti-spam.
• E-commerce (if present): add to cart, checkout, payment (test mode), confirmation email.
• Performance: loading of key pages, no obvious blocking resources.
• SEO: indexability, robots, sitemap, strategic redirects, essential tags.
• Security: admin accounts, suspicious attempts, file integrity if a tool is available.
The checklist must be actionable: a non-technical person should be able to perform some of the checks (e.g. form, display, navigation), while the more technical aspects (logs, cron, cache) can remain with the maintenance team.
Documenting ongoing SEO: what must remain stable
Effective maintenance also protects traffic. Yet many SEO declines result from undocumented changes: URL structure changes, content removal, modified titles, orphan pages, forgotten redirects, accidental noindex, etc.
Create a dedicated section in your documentation with:
• The permalink structure and the rules not to break.
• The pillar pages to preserve (URLs, titles, intent).
• The important redirects (and the reason for each one).
• The publishing conventions: categories, tags, internal linking, images.
• The tools used (SEO plugin, Search Console, analytics) and who has access to them.
To go further with a traffic-oriented maintenance approach, you can draw inspiration from a structured approach via How to Maintain SEO Optimization Over Time, then integrate the key points into your own procedures.
Clarify the hosting, resources, and constraints
Many maintenance issues boil down to: the server can no longer keep up, the PHP configuration is not suitable, the cache is poorly managed, disk space is full, or backups are saturating resources. Documenting the hosting environment helps you anticipate issues and diagnose them faster.

In your documentation, indicate:
• Hosting type (shared, VPS, dedicated, managed) and known limitations.
• Key settings: PHP version, memory_limit, max_execution_time, maximum upload size.
• Cache management: server, plugin, CDN, exclusion rules (cart, account, etc.).
• Backups: frequency, retention, location, tested restoration procedure.
• Monitoring: uptime, alerts, who receives notifications.
If you need to evolve your infrastructure or choose it more methodically, rely on concrete criteria for selecting a truly high-performance server, then record your decision (and the reasons for it) in your documentation.
Frame optimization: avoid uncontrolled tweaks
WordPress optimization is a slippery slope: a cache setting can break the display, minification can block a script, aggressive compression can degrade quality, and disabling a plugin can break a dependency. Your documentation should therefore describe your optimization policy:
• Which tools are authorized (and which are prohibited).
• Which metrics you monitor (Core Web Vitals, server response time, page weight).
• Which pages serve as references (home page, service page, blog, cart/checkout page).
• How to validate a gain (before/after, identical conditions, mobile verification).
• How to roll back if a setting degrades the experience.
If you are looking to rationalize your choices (plugins vs. manual settings), you can integrate into your documentation a technical decisions section inspired by this analysis of optimization with or without a plugin, in order to justify your trade-offs and avoid impulsive changes.
Document recurring maintenance according to your context (SMB, e-commerce, nonprofit)
The frequency and rigor of maintenance are not the same depending on the activity. An SMB often depends on its website for inbound requests, credibility, contact inquiries, and sometimes lead generation. Documenting routines adapted to your context (weekly, monthly, quarterly) makes the effort sustainable.
For example:
• Weekly: minor updates + form testing + quick check of key pages.
• Monthly: plugin audit, backup verification, security check, cleanup of unnecessary media, performance analysis.
• Quarterly: SEO review (content, redirects, weak pages), hosting review, full restoration test.
To formalize what is truly essential in a professional setting, you can align yourself with Maintenance for SMEs: What Is Essential, then adapt the checklist to your reality (budget, criticality, publishing frequency).
Choose a simple documentation format (and one that is actually maintained)
The best documentation is the documentation you keep up to date. So choose a medium that fits into your habits:
• A structured document (Google Docs\/OnlyOffice) with a table of contents.
• An internal wiki (Notion, Confluence, BookStack) to link pages and keep a history.
• A Git repository (README + \/docs) if you have a technical team.
• A combination: wiki for procedures + repository for technical elements (snippets, configuration).
In all cases, add:
• A date of last update for each section.
• An owner of the section (who guarantees its accuracy).
• A rule: every production change must be recorded (even in two lines).
Ready-to-use documentation plan template
Here is a framework you can reuse as is:
• 1. Site information sheet
• 2. Access and responsibilities (without secrets)
• 3. Architecture: theme, plugins, integrations
• 4. Procedures: updates, backups, restoration, incident
• 5. Testing checklist (before/after intervention)
• 6. SEO: key pages, URL rules, redirects, publication
• 7. Hosting: resources, cache, monitoring, limits
• 8. Performance: optimization policy, validations, rollback
• 9. Changelog: history of changes
• 10. Roadmap: planned improvements and technical debt
Turn documentation into a continuity tool (not paperwork)
The difference between useful documentation and documentation that gets ignored comes down to one point: does it help people take action, now? To achieve this, prioritize:
• Short, numbered, tested procedures.
• Described screenshots (if you add any), with the interface version.
• Explicitly justified decisions (we use X because…, we avoid Y because…).
• Scenarios: if the form no longer works, if the site is slow, if there is a 500 error, if an update is blocked.

Documenting these scenarios reduces dependence on one person. It is also a real safety net: in the event of an absence, a change of service provider, or a crisis (hacking, server outage), you retain control.
When to entrust maintenance (and how to document the collaboration)
If you delegate all or part of the maintenance, the documentation becomes an operational contract: scope, frequency, responsibilities, deadlines, escalation procedure, reporting. This avoids misunderstandings (I thought it was included) and speeds up every intervention.
In that case, document:
• The exact scope (updates, security, backups, performance, technical SEO).
• The frequency and maintenance windows.
• The validation process (who approves, how testing is conducted, where it is recorded).
• The reporting format (monthly, ticketing, recap email).
If you are looking for a structured service, you can consult Discover our site maintenance offers and then incorporate, into your documentation, the allocation of roles and the shared procedures.
Conclusion: documenting means making maintenance predictable
Documenting a WordPress site means investing in stability: you reduce wasted time, limit risks, speed up diagnostics, and secure future changes. Useful documentation is concise, actionable, maintained, and focused on your actual operations: access, architecture, procedures, testing, history, hosting, performance, and SEO. Start small (identity sheet + update procedures + checklist), then expand it as work is carried out. In just a few weeks, you will see the difference: fewer surprises, and maintenance that finally resembles a process.
