Technical SEO Checklist: 10 Fixes for Small Business Sites

Short answer: A technical SEO checklist covers the parts of your website that affect whether Google can crawl, index and show your pages. For a small business site, that means checking indexing, one version of each address, your sitemap, robots.txt, noindex tags, titles, broken links and redirects, mobile content, Core Web Vitals and canonical tags.

Technical SEO for small business sites is mostly about removing things that quietly stop Google finding your pages. Call it an SEO technical checklist or a technical SEO audit checklist: you can work through it with free tools, and each fix below quotes Google's own documentation.

Before you start: the free tools you need

Google Search Console. Google describes it as "a free service offered by Google that helps you monitor, maintain, and troubleshoot your site's presence in Google Search results".
PageSpeed Insights. Google's web.dev says it "surfaces data from the Chrome User Experience Report (CrUX)". Our free site speed test runs on it too.
A site crawler (optional). A desktop crawler such as Screaming Frog SEO Spider follows your links, which makes broken links and redirect chains easier to spot. Check the free version's limits on the vendor's site.

The technical SEO checklist

Ten checks. Each one says what it is, how to check it and what to do.

1. Your pages are actually indexed

Start with the Page indexing report in Search Console. It lists which URLs Google has indexed and why the rest aren't. Google "doesn't guarantee that all pages everywhere will make it into the Google index", so focus on your important pages: home, services, contact and key posts. You're looking for an important page in the wrong list.

To check one page, use the URL Inspection tool: it runs a live test and lets you request indexing after a fix.

2. One version of your site

Your site should answer at one address: https, with or without www, not all four combinations. Google "strongly recommends using HTTPS", and Search Console's HTTPS report shows how many indexed URLs are HTTP versus HTTPS.

What to check: type your address with http:// and with the other www form. Each should redirect to your single https:// version. Google says redirects are "a strong signal that the target of the redirect should become canonical".

3. An XML sitemap submitted in Search Console

An XML sitemap lists the URLs you want search engines to find. Google says you might not need one if your site is "small" ("about 500 pages or fewer"), well linked, and without many videos, images or news pages you want in search.

If you have one, keep it clean:

Use "fully-qualified, absolute URLs" for the canonical version of each page.
Stay within Google's limit of "50MB (uncompressed) or 50,000 URLs" per sitemap.
Submit it through the Sitemaps report in Search Console.

4. robots.txt isn't blocking important pages

robots.txt tells crawlers which URLs they can request. Google says it "is not a mechanism for keeping a web page out of Google".

What to check: open yoursite.co.uk/robots.txt and look for a leftover Disallow: /, or a Disallow line that covers your services or blog folder.

5. No accidental noindex tags

noindex (a meta tag or an HTTP header) tells Google not to index a page. Google drops a noindexed page from results "regardless of whether other sites link to it".

The trap is using noindex and a robots.txt block on one page. Google says that if a page is blocked by robots.txt, "the crawler will never see the noindex rule, and the page can still appear in search results".

What to check: search the source of your key pages for "noindex", or run them through URL Inspection, which shows an "Indexing allowed?" result.

6. Unique title tags and a clear H1

Google says to "make sure every page on your site has a title specified in the <title> element" and to "write descriptive and concise text". It warns against "repeated or boilerplate text", such as the same title on every page with one word changed.

For the heading, Google suggests making your main title stand out, for example by "putting the title text in the first visible <h1> element on the page". The SEO starter guide adds there's "no magical, ideal amount of headings a given page should have".

7. Broken links and redirect chains

A deleted page should return a 404 (not found) or 410 (gone) status, not a "not found" message with a success code (a soft 404).

Don't panic: Google says "404s don't harm your site's indexing or ranking". Do fix your own menus and internal links so they point at live pages.

If the content moved, use a permanent redirect (HTTP 301 or 308). Keep chains short: Google's crawlers "follow up to 10 redirect hops", but it's cleaner to point old URLs straight at the final page.

8. Mobile-friendly layout with the same content

Google says it "uses the mobile version of a site's content, crawled with the smartphone agent, for indexing and ranking". Its mobile-first indexing guide asks you to:

Make sure "your mobile site contains the same content as your desktop site".
"Use the same robots meta tags on the mobile and desktop site."
Avoid lazy-loading primary content "upon user interaction": Google won't load content that needs a swipe, click or typing to appear.

Google recommends responsive design because "it's the easiest design pattern to implement and maintain". Check on your own phone that no section is hidden.

9. Page speed and Core Web Vitals

Core Web Vitals are three metrics for real-world loading, interactivity and visual stability. Google's targets:

Largest Contentful Paint (LCP): "strive to have LCP occur within the first 2.5 seconds of the page starting to load."
Interaction to Next Paint (INP): "strive to have an INP of less than 200 milliseconds."
Cumulative Layout Shift (CLS): "strive to have a CLS score of less than 0.1."

web.dev says to measure these at "the 75th percentile of page loads, segmented across mobile and desktop devices". INP replaced First Input Delay (FID) as a Core Web Vital on 12 March 2024, so any checklist still quoting FID is out of date.

Search Console's Core Web Vitals report may show "No data available" for a small site. You can still test any page in our free site speed test.

10. Canonical tags and duplicate pages

One page often loads at several addresses, for example with a tracking parameter. Google picks one as the canonical. Google's SEO starter guide says duplicate content "is not a violation of our spam policies", but search engines "might waste crawling resources on URLs that you don't even care about".

You can state your preference. As well as redirects (check 2), a rel="canonical" link is "a strong signal" too. Google advises a self-referencing canonical on the main page, absolute URLs, and no mixed messages, such as one URL in your sitemap and another in the canonical tag.

A note on structured data. Structured data labels things like your business details. The key rule: "Don't mark up content that is not visible to readers of the page." FAQ rich results are no longer shown in Google Search (Google's changelog, May 2026). If you're a local business, pair this list with our Google Business Profile checklist.

Technical SEO for small business: what to fix first

Fix things in the order they block each other:

Indexing (checks 1, 4 and 5), because a page that isn't indexed can't appear in Google at all.
Duplicates and redirects (checks 2, 7 and 10), so every old address lands on one secure page.
Speed and mobile (checks 8 and 9).
The rest: sitemap and titles (checks 3 and 6), plus structured data.

Technical SEO audit checklist you can repeat every quarter

We suggest running this short SEO technical checklist every three months, and after any redesign or platform move:

Page indexing report: any important page newly not indexed?
http and www versions still redirect to one https address.
Sitemap submitted, with no errors in the Sitemaps report.
No stray Disallow in robots.txt and no noindex on key pages.
No broken internal links or redirect chains.
Core Web Vitals report, plus a speed test on mobile.
Canonical tags point at the pages you want shown.

FAQs

What is a technical SEO checklist?

A list of checks on how your site is built and served, rather than what it says: indexing, robots.txt and noindex rules, sitemaps, redirects and 404s, HTTPS, mobile content, Core Web Vitals, titles and canonical tags. It helps Google crawl and index the pages you care about.

How often should a small business check its technical SEO?

We suggest a short check every quarter using the list above, and a fuller one after any redesign, platform move or big batch of new pages. Search Console's reports show new indexing problems between checks, so look at them when you log in.

Can I do technical SEO myself without a developer?

Often, yes. Google says that if you run a small local business, "you can probably do much of the work yourself". Most checks here need only Search Console and a speed test. Some fixes, such as server redirects, may need your website platform's settings or a developer.

What is the difference between technical SEO and on-page SEO?

Technical SEO is about whether search engines can reach and store your pages: indexing, redirects, speed and the other checks above. On-page SEO is about what each page says: the words, headings and titles. Google's SEO starter guide covers both, aiming to make it easier for search engines "to crawl, index, and understand your content".

Do Core Web Vitals affect rankings?

Yes, as one part of page experience. Google says "Core Web Vitals are used by our ranking systems" and recommends good scores "for success with Search". It also says good scores don't guarantee "that your pages will rank at the top of Google Search results".

Is a technical SEO audit worth it for a small site?

It depends. An audit runs checks like the ten above in more depth, and if you can do them yourself, you may not need one. Google suggests getting help "when you're considering a site redesign (the earlier, the better), or planning to launch a new site", and says "No one can guarantee a #1 ranking on Google".
