KEY AREAS
Separate the questions before choosing the work.
Access and responses
Review failed requests, redirect destinations and server behaviour for important pages and resources. Confirm whether a reported error still exists before acting. The Google Penalty Checker can support an initial page review; its findings do not confirm a manual action.
Crawling and indexing
Investigate URLs that should appear in search. Separate access rules, index directives and page purpose instead of treating every exclusion as a problem. If you need to draft crawler access rules, use the robots.txt generator and review the output before publishing it.
Canonical and duplicate URLs
Review alternate URL versions, preferred representatives and consistency across internal links and sitemap entries. Similar pages may need consolidation or clearer distinct purposes. For a small site, the XML sitemap generator can help prepare a list of intended canonical URLs; it does not resolve conflicting signals for you.
Rendering
Compare the content delivered initially with the information available after scripts run. Check whether important content or links depend on interactions. Use the search engine spider simulator as a supporting check of the initial HTML; confirm rendering separately in Search Console.
Architecture and links
Make important pages reachable through useful navigation and contextual links. Broken destinations and disconnected pages can interrupt visitors and discovery.
Performance and usability
Investigate page loading and interaction on real devices and appropriate testing tools. Separate an initial server-response check from full browser or field-performance evidence.
Redirects and site changes
Review the intended destination, unnecessary hops and missing replacements when URLs change. Keep a record of what was moved and what should remain available.
Structured data
Check supported markup against the visible page and current search-engine requirements. Correct markup does not replace accurate content or guarantee a special result.
