Technical SEO Checklist for Small Business Websites

Technical SEO is the work that makes your website easy for search engines to find, read and store. It sits underneath your content. Great service pages will not rank if Google cannot crawl them, or if it sees three different versions of the same page.

Small business sites often have the same handful of problems. A theme blocks search engines after launch. Old pages return errors. Images slow the homepage to a crawl. The good news is that most of these are quick to fix once you know where to look.

You do not need expensive software. These free tools cover almost everything in this checklist:

• Google Search Console – shows how Google crawls and indexes your site.
• Bing Webmaster Tools – the same for Bing, which also feeds several AI assistants.
• PageSpeed Insights – measures Core Web Vitals from real users and lab tests.
• Google's Rich Results Test – checks your structured data.
• A crawler such as Screaming Frog SEO Spider (free for small sites) to list every URL, status code and title.

Start here, because nothing else matters if your pages are not in Google's index.

1. Verify your site in Search Console. Add a Domain property so it covers http, https, www and non-www together. Verify it with a DNS TXT record at your domain registrar.
2. Check robots.txt. Visit yourdomain.com/robots.txt. Make sure it does not contain Disallow: / for all user agents. That single line blocks your whole site.
3. Look for stray noindex tags. On WordPress, go to Settings > Reading and confirm "Discourage search engines from indexing this site" is unticked. Many sites launch with it still switched on.
4. Submit an XML sitemap. Most SEO plugins create one automatically (for example /sitemap_index.xml with Yoast). In Search Console, open Indexing > Sitemaps, paste the URL and click Submit.
5. Review the Pages report. Go to Indexing > Pages. Read the reasons listed under "Why pages aren't indexed". Focus on pages you actually want to rank.
6. Inspect your key pages. Paste your homepage and top service pages into the URL Inspection bar. Check that each says "URL is on Google". If not, fix the issue and click "Request indexing".

Search engines should see one version of each page. Duplicates split your ranking signals and waste crawl time.

Pick one preferred domain

Choose either www or non-www, always on HTTPS. Set a permanent 301 redirect from every other version to that one. Test all four combinations in your browser and confirm they land on the same address.

Add canonical tags

Every indexable page should have a self-referencing rel="canonical" tag in its head. SEO plugins handle this on most CMS platforms. Pages with filter or tracking parameters should point their canonical at the clean URL.

Clean up 404s and redirect chains

1. Run a crawl and export all URLs that return 4xx or 5xx status codes.
2. For deleted pages that had traffic or links, add a 301 redirect to the closest relevant page.
3. Update internal links so they point straight at the final URL, not through a redirect.
4. Collapse any chain (A to B to C) into a single hop (A to C).

Google uses Core Web Vitals as part of its page experience signals. A page passes when at least 75% of real visits meet the "good" threshold for each metric.

To check your scores, enter a URL into PageSpeed Insights. The top section shows real-user data where Google has enough of it. In Search Console, the Experience > Core Web Vitals report groups slow URLs so you can fix templates rather than single pages.

Google indexes the mobile version of your site. If content, links or structured data are missing on mobile, Google effectively does not see them.

• Open your site on a real phone. Check that text is readable without zooming and buttons are easy to tap.
• Make sure menus, service details and contact information are present on mobile, not hidden or removed.
• Confirm the viewport meta tag is in your page head.
• Install a valid SSL certificate and serve every page over HTTPS.
• Fix "mixed content" warnings, where an HTTPS page loads an image or script over plain HTTP.
• Keep your CMS, theme and plugins updated. A hacked site can be flagged in search results.

If security has been neglected for a while, a wider cybersecurity review is worth considering alongside the SEO work.

Good structure helps both visitors and crawlers understand what matters most.

1. Keep important pages shallow. Aim for any key service page to be reachable within three clicks of the homepage.
2. Write a unique title tag for every page. Lead with the main keyword and keep it to roughly 60 characters so it is less likely to be cut off.
3. Write a meta description for key pages. Google may rewrite it, but a clear summary still improves click-through.
4. Use one H1 per page, followed by H2 and H3 headings in order.
5. Use clean URLs such as /services/plumbing-repairs rather than /?p=123.
6. Link related pages together with descriptive anchor text, not "click here".
7. Add alt text to meaningful images so search engines and screen readers know what they show.

Structured data (schema markup) tells search engines who you are and what you offer in a machine-readable format. For most small businesses, start with:

• Organization or LocalBusiness on the homepage, with your name, logo, address, phone and social profiles.
• BreadcrumbList on inner pages, so Google can show a clean path in results.
• Article or BlogPosting on blog posts, with author and date.

Add it as JSON-LD, then test each template in the Rich Results Test. Keep your business name, address and phone identical to your Google Business Profile.

Look at Search Console once a month. It emails you about new issues, but a regular check catches slow drift. Run a full crawl every quarter and after any redesign, migration or plugin change. Redesigns are the most common moment for small sites to lose rankings, usually because redirects were missed.

If you prefer a written report with priorities, a professional website audit covers this list and more, ranked by impact.
