How to do a quick SEO audit on a small website

Ce contenu est en anglais.

A quick SEO audit is a structured pass through your site to find the problems that are most likely to hold back your visibility in search. You do not need expensive software or technical training to do one. This guide gives you an ordered checklist for a small site, based on Google Search Central documentation as it stood in October 2026, and it shows you what to fix first.

What a quick audit can and cannot do

A quick audit is a health check, not a ranking guarantee. It tells you whether search engines can reach your pages, understand them and present them sensibly in results. It does not tell you why a competitor outranks you, and it cannot replace good content. Think of it as removing obstacles so that your best pages get a fair chance.

Set aside an hour or two and decide your scope before you begin. For a site of up to a few dozen pages, you can look at every page. For a larger site, choose a sample that includes your home page, your most important category or service pages, a few articles and a couple of tool or product pages. Keep a simple spreadsheet with columns for the URL, the issue, the fix and the status, so the audit turns into a work list.

The checklist below follows the order in which problems usually matter. If a page cannot be crawled or is marked noindex, nothing else on the list will help it, so those checks come first.

Step 1: Check that pages can be crawled and indexed

Start with your robots.txt file at the root of your site. Google explains that the file tells crawlers which URLs they can access, mainly to avoid overloading your site. Confirm it does not block sections that you want found, and that it points to your sitemap. Remember that robots.txt is not a way of keeping a page out of search results. For that, Google recommends a noindex rule, delivered as a meta tag or an HTTP header.

Next, look for stray noindex tags. A template change or a plugin setting that was meant for a staging site can leave noindex on live pages, which quietly removes them from results. View the source of a handful of key pages and search for the word noindex, or use a checker that reports it for you.

Finally, check Google Search Console if you have it set up. The indexing report shows which pages are indexed and gives reasons for those that are not. If your important pages are listed as excluded, fix that before anything else.

Step 2: Review your sitemap

A sitemap is a file that lists the URLs you want search engines to know about. Google says a single sitemap can hold up to 50MB uncompressed or 50,000 URLs, and larger sites should split it and use a sitemap index. A small site will not come near those limits, but the principle still applies: list only the canonical URLs that you want indexed.

Check that every URL in the sitemap returns a normal page, not a redirect, an error or a noindex page. Google ignores the priority and changefreq values, so there is no need to spend time tuning them. The lastmod value is only used if it is consistently and verifiably accurate, so either keep it honest, meaning it changes when the main content changes, or leave it out. Changing a copyright year is not a significant update.

Make sure the sitemap address is listed in robots.txt and, if you use Search Console, that you have submitted it there.

Step 3: Check titles and meta descriptions

Each page should have a title element that is unique and describes its content. Google gives no fixed length limit, but it truncates title links to fit the width of the device, so put the important words first. Avoid vague titles such as Home or Profile, avoid repeating the same boilerplate across many pages, and avoid stuffing keywords. Where it helps, add your site name briefly at the start or end, separated by a hyphen, colon or pipe.

Be aware that Google sometimes rewrites titles if it finds one that is empty, repetitive, outdated or inaccurate. If the title you see in results differs from the one you wrote, that is a hint to improve the original.

Meta descriptions should be short, one or two sentences, unique to each page and focused on the most relevant points. Snippets usually come from the page content, but the description is sometimes used, so it is still worth writing well. A meta tag checker can list the titles and descriptions across your key pages, which makes duplicates and gaps easy to spot.

Step 4: Look at headings, content and images

Every page should have one clear main heading that matches what the page is about, followed by subheadings that break the content into logical parts. Google advises writing for people rather than search engines, keeping content original and well organised, and updating or removing outdated pages. If two pages answer the same question, merge them or make the difference between them obvious.

Read your top pages as a newcomer would. Does the opening paragraph answer the question the page promises to answer? Is there anything that is out of date, such as old figures, expired offers or references to last year? Thin pages with little useful content are candidates for improvement or removal.

For images, add alt text. Google describes it as a short but descriptive piece of text that explains the relationship between the image and your content. Place images near relevant text, and describe what the image shows rather than packing in keywords.

Google mainly finds new pages by following links from pages it already knows, so internal links matter. Every page you care about should be linked from at least one other page on your site, and ideally from several relevant ones. A page that nothing links to is harder to discover and signals less importance.

Check that your links are crawlable. Google generally needs an anchor element with an href attribute. Links built from a span, or an anchor that only has an onclick handler and no href, may not be followed. Also review the anchor text. Good anchor text is descriptive and makes sense out of context, while click here and read more tell neither users nor search engines anything about the destination.

Look for orphan pages and for important pages that sit many clicks away from the home page. Adding a few well-placed links from your strongest pages is often one of the quickest improvements in an audit.

Every URL should return the status you intend. Google treats all 4xx errors except 429 in the same way: URLs that are already indexed and return a 4xx status code are removed from the index. A 5xx or 429 error makes Google's crawlers slow down temporarily, and if the errors persist, indexed URLs are eventually dropped. Soft 404s, where a page returns a normal status but shows an error message or empty content, are reported in Search Console.

For pages that have moved, use a server-side permanent redirect. Google says permanent redirects tell it the target should be the canonical URL, and that server-side redirects have the highest chance of being interpreted correctly. A 302 is for genuinely temporary moves. Avoid chains in which one redirect leads to another, because each extra hop adds delay and risk.

Run a broken link check across your pages, covering both internal links and links to other sites. Fix internal links at the source rather than relying on redirects, and replace or remove external links that no longer work. A separate guide on this site covers the process in detail.

Step 7: Structured data and the basics of speed, mobile and HTTPS

Structured data is markup that describes what a page contains, such as an article, a product, an organisation or a set of questions and answers. It is optional, but if you add it, validate it so that errors do not undermine the effort. Make sure the markup describes content that is actually visible on the page.

Finally, confirm the basics are in place. Your site should load over HTTPS with a valid certificate and redirect any HTTP address to the HTTPS version. It should display properly on a phone, since many visitors will arrive that way, and pages should load quickly enough that people do not give up. Specialist tools can measure these, and you can check the certificate and response headers with simple lookups.

These checks are less likely than crawling and indexing problems to make a page vanish from results, but they affect how people experience your site once they arrive.

Prioritise fixes and repeat the audit

Sort your spreadsheet by impact. Anything that stops pages being indexed comes first, then broken links and redirect chains, then titles and descriptions on your most important pages, then the finer improvements. Fix a batch, wait for search engines to recrawl, and check again in Search Console.

Changes do not show up instantly. Google notes that updated titles can take days to weeks to appear. Record the date of each fix so you can match it with later changes in your data. A quick audit every quarter, or after any redesign or migration, keeps small issues from building up. Run the checks in this guide against the pages that matter most, and use the tools below to speed up the repetitive parts.

Questions fréquentes

How often should I run an SEO audit on a small site?

A quick audit every quarter is a reasonable rhythm for most small sites, with an extra one after a redesign, a change of domain or a platform migration. Those are the moments when noindex tags, broken links and redirect problems are most likely to appear, so catching them early limits the damage.

Does a page blocked in robots.txt stay out of search results?

Not reliably. Google says robots.txt is not a mechanism for keeping a page out of Google, and a blocked URL can still appear in results without a description if other sites link to it. To keep a page out of results, use a noindex meta tag or HTTP header, or protect it with a password.

Do I need to set priority and changefreq in my sitemap?

No. Google ignores both values. It uses lastmod only when it is consistently and verifiably accurate, so keep it matched to genuine content changes or leave it out. The most useful thing a sitemap can do is list canonical URLs that return a normal page and that you want indexed.

What is the right length for a page title?

Google gives no fixed limit. It truncates title links to fit the device width, so place the most important words first and keep the title descriptive and unique. Avoid vague wording and repeated boilerplate. Google may rewrite a title that is empty, outdated, inaccurate or repetitive.

Should I use a 301 or a 302 redirect when a page moves?

Use a permanent server-side redirect, such as a 301, when a page has moved for good. Google treats it as a signal that the new URL is the canonical one. A 302 suits temporary situations, because Google follows it but may keep the original URL in results.
