SEO Audit Checklist

What this tool does

An SEO audit means checking the health of a site across everything that affects how it performs in search, and it is easy to lose track of what you have and have not looked at. This is an interactive checklist that lays out the key tasks across five areas, so you can tick each one off as you go and see what is left.

How to use it

Work down the list and tick each item as you complete it. There is no scoring or sign-up; it is a place to keep track while you review your site, so you can step away and come back without losing your place. Treat it as a map of what to check rather than a test to pass.

The five areas it covers

Technical SEO is the foundation: whether search engines can reach, read, and trust your site. It covers site speed, mobile-friendliness, crawl errors, an SSL certificate for HTTPS, your XML sitemap, and your robots.txt file. If this layer is broken, nothing above it can work properly.

On-Page SEO is how well each page is put together: title tags, meta descriptions, a sensible header structure (one H1, then H2s), keyword usage, internal linking, and alt text on images. Several of these have their own tools here, the meta tag generator and the title and description length checkers for the tags, and the keyword density checker for your copy.

Off-Page SEO is your reputation beyond your own site: the quality of links pointing to you, brand mentions, your social presence, and what your competitors' backlinks look like. Content Audit looks at the substance: duplicate content, the quality and relevance of what you publish, gaps where you are missing topics your audience searches for, and your calls to action. Analytics and Reporting closes the loop, making sure you have Google Analytics and Search Console set up, that you are watching your traffic, and that conversions are being tracked, so you can actually see whether the rest is working.

Working through an audit

Order helps. Start with the technical foundation, because a fast, secure, crawlable, mobile-friendly site is what everything else rests on. Then move to on-page, then content, then off-page, and keep analytics running throughout so you can measure the effect of your changes. One honest point worth holding onto: a checklist gets you organised, but ticking a box is not the same as doing the work well. "Optimise title tags" can take five minutes or a careful afternoon, and the difference shows in your results. Treat this as a thorough starting framework rather than an exhaustive list, since large or specialised sites will have their own concerns to add. For the structured-data side of a technical review, the schema markup generator is a useful companion.
