Content revised 20 October 2026.
An SEO code review checks whether the implementation supports the page’s content and intended search behaviour. Start with the public output, then trace a demonstrated problem to the template or plugin responsible.
Check the document’s main signals
Review the page title, canonical, robots instructions and language declaration. Check for duplicate or conflicting output from the theme and SEO plugins. Make sure the primary content and heading describe the page rather than a generic template repeated across the site.
Keep navigation usable
Inspect the links that connect important pages. A navigation control can look polished while failing to expose a usable destination. Test the actual links and keyboard operation as well as the desktop appearance. Forms and buttons should have clear labels that match their function.
Inspect rendering and media
- Confirm important text appears in the rendered page.
- Check meaningful image alternatives and dimensions.
- Review unnecessary scripts and duplicated assets.
- Test responsive layouts and expandable content on a phone.
Change the responsible component
If Rank Math already owns metadata and structured data, fix or extend that configuration rather than pasting another conflicting head snippet into the theme. Keep code changes scoped, reversible and tested against representative page types. Clearing a syntax error is only the first check; the generated information must be correct too.
Verify the result
Compare the output before and after the repair, then test navigation, media and enquiry functions. Record the fault you resolved. There is no special source-code format that guarantees a ranking; the implementation should make accurate content available, consistent and usable.
