Quick answer: what technical SEO does a London, Ontario business need?
A London business needs 12 technical fixes: crawl and indexing checks (robots.txt, sitemap, noindex, canonical), speed and mobile fixes, LocalBusiness and FAQ schema, and clean links with one secure address. Start with the indexing checks, since they take minutes and can hide a whole site. Most small sites need two or three of the 12, not all of them.
Technical SEO London Ontario work comes down to 12 fixes that decide whether Google can find, read and trust your website. Most small business sites in Middlesex County are held back by two or three of them, not all twelve. Our SEO services in London, Ontario start with this check, because content and links only pay off once the site underneath them works.
This guide ranks the 12 fixes by how often they hold local sites back, tells you how to check each one with free tools, and says how long each takes. The fundamentals are covered in our post on technical SEO basics, so here we go straight to the fixes.
Why technical SEO London Ontario businesses need is different from a national site
A local business needs technical SEO that protects a small site, a Google Business Profile link and a handful of service pages, not a ten-thousand-page crawl budget. The work is narrower, and that makes it faster to finish.
A plumber in Byron, a dental clinic on Richmond Row or a contractor in Old East Village usually has between 8 and 60 pages. Google can crawl a site that size in a short visit, so crawl budget is rarely the problem. The problems are smaller and more fixable: a page set to noindex by mistake, a slow phone experience, a missing LocalBusiness block, two versions of the same address.
Technical errors also cost a local business more than they cost a national one, because the same few pages carry every enquiry. If your homepage is slow on a phone in Masonville or your contact page is blocked from indexing, you lose the searcher who was ready to call.
Google's own documentation, Google Search Essentials, sets the baseline. Pages must be crawlable, indexable and free of spam techniques before anything else counts. The 12 fixes below are the practical version of that baseline for a small site, checked with tools that cost nothing.
What this post does not cover
We skip title tags, headings and image alt text, which belong to on-page work. Those are in our on-page SEO checklist. We also skip the broader plan for ranking in the city, which lives in our guide to search engine optimization in London, Ontario. This post is about the machinery under the pages.
Fixes 1 to 4: crawling and indexing problems that hide pages from Google
Four fixes decide whether Google can reach and keep your pages: robots.txt, the XML sitemap, noindex tags and canonical tags. A mistake in any one can remove a page from search results entirely.
Fix 1: Check that robots.txt is not blocking the site
Open yourdomain.ca/robots.txt in a browser. If you see a line reading Disallow: / under User-agent: *, the whole site is blocked from crawling. This happens most often after a redesign, when a developer blocks the staging site and the setting survives the launch.
A healthy file for a small business is short. It allows crawling, blocks only admin or cart areas if they exist, and points to the sitemap. Time to fix: 10 minutes, once you have access to the file.
Fix 2: Publish an XML sitemap and submit it
An XML sitemap lists the pages you want indexed. Check yourdomain.ca/sitemap.xml, then submit it in Google Search Console under Sitemaps. It should list only live pages that return a normal 200 response. Remove redirected pages, error pages and test pages.
A sitemap that lists 80 URLs when the site has 40 real pages sends Google to dead ends and wastes the visit. Time to fix: 30 minutes with a plugin or a hand-edited file.
Fix 3: Find and remove accidental noindex tags
A noindex tag tells Google to leave a page out of search. It is useful for thank-you pages and internal search results. It is a disaster on a service page. In Search Console, open the Pages report and look at the reasons listed under Not indexed, in particular Excluded by noindex tag.
Also check the page itself: right-click, view source and search for noindex. Some WordPress themes add the tag to every page while a site is in maintenance mode, and the setting stays on after the launch. Time to fix: 5 minutes per page, plus a re-crawl request.
Fix 4: Set one canonical URL per page
A canonical tag names the preferred address when the same content can load at several addresses. Without it, Google may treat the http and https versions, the www and non-www versions and the versions with tracking parameters as separate pages that compete with each other.
Each page should carry a canonical tag pointing to its own clean address. Time to fix: 30 minutes on a typical small site, since most themes and plugins add the tag once it is switched on.
After these four fixes, run the URL Inspection tool on your five most important pages. It tells you whether Google has indexed each page, which version it chose as canonical and when it last crawled it.
Fixes 5 to 8: speed and mobile problems that cost you phone searchers
Four fixes decide how the site behaves on a phone: Core Web Vitals, image weight, caching and the mobile layout. Google indexes the mobile version of a page first, so a slow or broken phone experience is the version Google judges.
Fix 5: Pass the three Core Web Vitals
Core Web Vitals measure how fast the main content appears, how quickly the page responds and how much it shifts while loading. The published targets are Largest Contentful Paint at or under 2.5 seconds, Interaction to Next Paint at or under 200 milliseconds and Cumulative Layout Shift at or under 0.1.
Test your homepage and your top service page in PageSpeed Insights, and read the field data section first, since that comes from real visitors. Small sites with no field data yet should use the lab results as a guide. Time to fix: from an hour to a few days, depending on what is slowing the page.
Fix 6: Reduce image weight
Oversized images are the most common reason a small business page is slow. A photo straight from a phone can weigh several megabytes, and the same photo displayed at 800 pixels wide needs a fraction of that. Resize images to the size they display at, and use modern formats such as WebP.
Check the Performance report in PageSpeed Insights, which lists images that could be smaller. Time to fix: 1 to 3 hours for a site of 20 pages, less if a plugin handles compression automatically.
Fix 7: Turn on caching and compression
Caching lets a returning visitor reuse files already downloaded, and compression shrinks the files that do travel. Both are server settings. On a shared host they are often one switch in a plugin or a few lines in the server configuration.
The PageSpeed Insights report flags missing caching as Serve static assets with an efficient cache policy. Time to fix: 30 minutes to an hour, plus a retest.
Fix 8: Make the mobile layout usable
Open your own site on a phone and try the three actions a customer takes: tap the phone number, find the address and fill in the form. Text should be readable without zooming, buttons should be far enough apart to tap without error and nothing should scroll sideways.
A common failure is a phone number that is plain text instead of a tap-to-call link. Time to fix: 15 minutes for the call link, longer if the theme needs a layout change.
Fixes 9 and 10: structured data that tells Google who you are
Two fixes cover structured data: a LocalBusiness block that states who you are and where you work, and a FAQ block where the page really has questions and answers. Structured data does not guarantee rich results, but it removes guesswork for search engines and for the AI tools that read the same markup.
Fix 9: Add LocalBusiness schema that matches your Google Business Profile
LocalBusiness schema describes your business in a form machines read: name, address, phone number, hours, service area and links to your profiles. Every detail should match your Google Business Profile exactly, down to the suite number and the way the phone number is written. Our guide to NAP consistency explains why a mismatch weakens trust.
Schema.org defines the vocabulary, and a business with a service area, such as a contractor travelling across London, St. Thomas and Strathroy, should list the areas it serves. Time to fix: 1 to 2 hours, including validation.
Fix 10: Add FAQ markup where a page really answers questions
FAQPage schema belongs on a page that shows the same questions and answers to the reader. The markup must mirror the visible text. Marking up questions that do not appear on the page breaks Google's guidelines and can lose the markup.
Validate both blocks with the Schema Markup Validator and the Rich Results Test. Fix errors first, warnings second. Time to fix: 1 hour per page type once the first template is right.
Fixes 11 and 12: site structure and security that keep authority in one place
Two fixes keep your authority consolidated: clean internal links and redirects, and one consistent secure address. Both are about making sure every signal points to a single version of each page.
Fix 11: Repair internal links and redirect chains
Every important page should be reachable within three clicks of the homepage, and no page should be an orphan with no internal links. Broken links return a 404 error and waste the visit. Redirect chains, where one address redirects to a second and then a third, slow the page and dilute signals.
Crawl the site with a free crawler such as Screaming Frog, which is free up to 500 URLs and covers most local sites, or read the Pages report in Search Console. Replace each redirect with a direct link to the final address. Time to fix: 2 to 4 hours for a typical small site.
Fix 12: Use https and one version of the address everywhere
The site should load on https only, and the http, non-www and www versions should all redirect to the single version you chose. Check this by typing each variation into a browser. If any one loads without redirecting, search engines can see duplicate copies of the site.
Also check that images, scripts and stylesheets load over https, since a single insecure file can trigger a browser warning. Time to fix: 30 minutes to an hour, and your host can usually switch on the certificate at no extra charge.
Fix priority table: effort, impact and who can do it
The fixes with the largest effect on a small local site are the indexing ones, because they decide whether a page can rank at all. Speed and structure fixes follow. The table sorts all 12 by effort and impact.
| Fix | Effort | Impact on a local site | Who can do it | Time to fix |
|---|---|---|---|---|
| 1. robots.txt check | Low | High if blocked | Owner with host access | 10 minutes |
| 2. XML sitemap | Low | Medium | Owner or developer | 30 minutes |
| 3. Accidental noindex | Low | High if present | Owner or developer | 5 minutes per page |
| 4. Canonical tags | Low | Medium | Plugin or developer | 30 minutes |
| 5. Core Web Vitals | Medium to high | Medium to high | Developer | 1 hour to a few days |
| 6. Image weight | Low to medium | Medium | Owner with a plugin | 1 to 3 hours |
| 7. Caching and compression | Low | Medium | Host or plugin | 30 to 60 minutes |
| 8. Mobile layout | Low to medium | High for calls | Owner or developer | 15 minutes to a day |
| 9. LocalBusiness schema | Medium | Medium | SEO provider or developer | 1 to 2 hours |
| 10. FAQ schema | Low to medium | Low to medium | SEO provider or developer | 1 hour per page type |
| 11. Internal links and redirects | Medium | Medium | Owner or SEO provider | 2 to 4 hours |
| 12. https and one address | Low | Medium to high | Host or developer | 30 to 60 minutes |
Read the table from the top. Fixes 1 and 3 take minutes and are the only ones that can make a site invisible overnight, so they come first even though they are rarely the cause. Fix 5 takes the longest, and it is where most small business sites need outside help.
Technical fixes rarely lift rankings on their own, because ranking also depends on content, links and your Google Business Profile. What they do is remove the obstacles, so that the other work counts. For a business weighing priorities, our guide to reading your SEO audit shows how to sort findings by impact.

How to run this technical SEO check yourself in an afternoon
You can run the whole check in about three to four hours with free tools, in a fixed order. Doing it in order matters, since an indexing problem makes every later fix pointless.
- Open Search Console. If your site is not verified, verify it first. Everything below uses it. The setup takes about 15 minutes with a DNS record or an HTML tag.
- Read the Pages report. Note how many pages are indexed and the reasons the others are not. A gap of a few pages is normal, and a gap of half the site is a problem.
- Check robots.txt and the sitemap. Fixes 1 and 2, about 40 minutes together.
- Inspect your five key pages. Use URL Inspection on the homepage, your top service page, your contact page and two others. Look for noindex and for the canonical Google chose.
- Test speed on a phone. Run PageSpeed Insights on the same five pages and record the three Core Web Vitals numbers.
- Test the schema. Paste each key page address into the Rich Results Test and the Schema Markup Validator.
- Crawl the site. Run a free crawler and export the broken links and redirect chains.
- Type the address four ways. Try http, https, www and non-www, and confirm they all land on one version.
- Write down the results. A one-page list of fixes in the table order is the work plan.
When to hire help
Do the first four steps yourself, since they are quick and need no coding. Hire help when speed work needs a developer, when schema needs writing or when the crawl turns up more than a few dozen broken links. A useful rule: if a fix needs you to edit theme files or server settings and you are not comfortable doing so, the cost of a mistake outweighs the cost of help.
Sites in St. Thomas, Strathroy, Woodstock and Ingersoll follow the same process. The checks do not change by town, only the local details in the schema do.
