AIOSEO Audit: WordPress SEO Checklist for Site Health and Crawlability

An AIOSEO Audit for WordPress is a practical way to review site health and crawlability before small issues become larger SEO problems. It helps you check whether search engines can find, understand, and prioritise the right pages, while also highlighting technical and on-page improvements that support better content discovery.

This kind of audit is not about chasing a perfect plugin score. It is about checking the real factors that affect WordPress SEO: page titles, meta descriptions, permalinks, internal links, XML sitemaps, robots directives, canonical URLs, redirects, speed, mobile usability, and whether your content is structured in a way that makes sense for users and crawlers alike.

What an AIOSEO Audit should cover

All in One SEO, like other WordPress SEO plugins, can help surface basic checks for titles, descriptions, schema, and site-wide settings. Useful as that is, the audit itself should go beyond plugin prompts and look at the whole website. WordPress core, your theme, other plugins, hosting, and custom code can all affect SEO outcomes in different ways.

Start with the basics: confirm that the site has a clear homepage, sensible navigation, and pages that serve a distinct purpose. Review whether posts, pages, categories, tags, and custom post types are being used intentionally. A site with too many overlapping archives or thin pages can create unnecessary duplication and make crawl paths less efficient.

If you are setting up or reviewing SEO tools, compare your plugin approach carefully. WordPress sites generally need only one primary SEO plugin, and combining overlapping plugins can create duplicate metadata, conflicting canonicals, or sitemap issues. For a broader technical baseline, Google’s SEO Starter Guide from Google Search is a sensible reference point.

On-page SEO checks for titles, content, and URLs

On-page SEO focuses on how each page is written and presented. Title tags should describe the page clearly and reflect search intent. Meta descriptions do not directly guarantee rankings, but they can influence how your page is presented in search results, so they should be accurate and useful rather than stuffed with repeated phrases.

Review headings so each page has one clear topic and a logical structure. Use descriptive subheadings, but do not force the same keyword into every line. Good internal linking matters too: link related posts, services, products, and guides where it helps readers move naturally through the site. That is especially useful for orphan pages, which may exist but are difficult to discover without contextual links.

Permalinks should also be checked. Clean, descriptive URLs are easier to share and maintain than long, unclear ones. If you change a URL, map the old version to the new one with a proper redirect and update any internal links. For WordPress-specific configuration, the WordPress permalinks settings documentation is a helpful reference.

Technical SEO: crawlability, indexing, canonicals, and robots

Crawlability means search engines can access a page. Indexing means they have chosen to store it in their search index. A page can be crawlable but still not indexed, depending on factors such as noindex directives, canonicalisation, internal links, duplication, content quality, and server responses.

Check XML sitemaps, robots.txt, and robots meta tags together rather than in isolation. Sitemaps help search engines discover preferred URLs, but they do not force indexing. Robots.txt controls crawler access, but it does not directly remove indexed URLs. If you block an important page in robots.txt, crawlers may not reach a noindex tag on that page. Google’s robots.txt guidance explains the distinction clearly.

Canonical URLs also deserve careful review. A canonical tag is a signal about the preferred version of a page, not an absolute command. It should normally point to a relevant, indexable URL, and it should not be used to send unrelated pages to a homepage or to a broken destination. After any plugin change, theme change, or migration, check the rendered page source rather than relying only on settings screens.

Site health, speed, security, and Core Web Vitals

Site health includes performance, technical stability, and security. WordPress SEO audits should review website speed, image optimisation, caching behaviour, theme efficiency, database load, and any external scripts that slow down rendering. Core Web Vitals are also worth checking: Largest Contentful Paint measures loading of the main content, Interaction to Next Paint reflects responsiveness, and Cumulative Layout Shift measures visual stability.

Performance data can vary depending on test location, device type, server load, and cache state, so do not chase a single score at the expense of usability. Major changes to caching, minification, or image delivery should be tested on staging first, with a backup in place. WordPress security matters too, because malware, injected spam, and unauthorised redirects can damage trust and search visibility. For maintenance and recovery planning, WordPress backups guidance is worth reading before making significant technical edits.

Image SEO belongs in this section as well. Use descriptive filenames, sensible dimensions, compression, and meaningful alternative text where appropriate. Alt text should describe the image for accessibility; it should not be used as a keyword dump. Decorative images may not need detailed alt text.

Special cases: WooCommerce, local SEO, multilingual sites, and migrations

Different WordPress site types need different checks. WooCommerce stores should review product pages, product categories, product schema, filters, mobile usability, and out-of-stock handling. Faceted navigation can create many URL combinations, so think carefully before indexing parameterised pages. Product and category pages often serve different intent, and they should not be treated as interchangeable.

For local SEO, make sure business details are consistent, location pages contain genuinely useful information, and service content is not duplicated across multiple cities with only the place name changed. For multilingual sites, use proper language targeting, review translation quality, and check that canonicals and sitemaps reflect the intended structure. Hreflang can help search engines understand language versions, but it is not a ranking guarantee.

Migrations and redesigns need extra care. Before changing themes, domains, HTTPS setups, or permalinks, create a full backup, crawl the existing site, preserve valuable metadata, map redirects, update internal links, and verify noindex and canonical settings after launch. Temporary ranking or traffic changes can happen after major changes, so monitor Google Search Console and Google Analytics 4 carefully. If you need a structured starting point, the free website SEO audit from Backlink Works can complement your own technical review.

How to run the audit in a practical order

A simple audit process usually works better than a long checklist done at random. Start with crawlability and indexing, then move to on-page quality, internal linking, schema, and performance. After that, check special areas such as WooCommerce, local pages, or multilingual versions if they apply to your site.

Use Google Search Console to see which pages are discovered, crawled, indexed, or excluded, but do not treat it as an instant verdict. The URL Inspection tool can be useful, yet it does not guarantee inclusion in search results. Compare Search Console data with GA4 so you can separate search visibility signals from user behaviour and conversions. If you are planning broader link strategy alongside technical work, Backlink Works’ backlink building process guide may help you connect content quality with authority-building work.

Finally, review the plugin layer itself. Yoast SEO, Rank Math, All in One SEO, and SEOPress can each support WordPress SEO workflows, but the right choice depends on your site type, technical requirements, budget, and team workflow. Treat plugin scores and prompts as guidance, not as proof that your SEO is complete.

Conclusion

An AIOSEO Audit is most useful when it checks the whole WordPress setup rather than only plugin settings. A solid audit looks at content quality, titles, metadata, internal linking, sitemap structure, robots controls, canonicals, redirects, page speed, mobile usability, and site security in a single workflow.

Used regularly, that process helps you spot problems early, keep important pages discoverable, and maintain a site that is easier for people and search engines to navigate. The goal is not perfection in a plugin report; it is a website that is technically sound, well structured, and maintained with clear SEO intent.

Frequently Asked Questions

What is the difference between crawling and indexing?

Crawling is when search engines access a page, while indexing is when they store it for possible appearance in search results. A page can be crawlable without being indexed.

Do SEO plugin scores mean my site is optimised?

No. Plugin scores are helpful prompts, but they are not confirmed ranking factors. They should be used alongside human review, content judgement, and technical checks.

Should I use more than one WordPress SEO plugin?

Usually no. Running multiple full SEO plugins can cause duplicate titles, conflicting canonicals, or sitemap issues. One primary SEO plugin is normally enough.

Does submitting an XML sitemap guarantee indexing?

No. A sitemap helps discovery, but indexing still depends on crawlability, quality, duplication, canonical signals, internal links, and search engine decisions.
