Technical SEO Services: Search Engine Optimization That Lets Google and AI Crawl, Index and Trust Your Site
Great content cannot rank if search engines cannot reach it, load it or understand it, and the same goes for your online presence in AI search. 1307 Digital's technical SEO services fix the infrastructure behind your website so Google, Bing and AI assistants can crawl, index and trust every page that matters.
We are a Toronto digital marketing agency, SEO agency and Google Partner, working with businesses across Canada, from Toronto to Vancouver. We find technical problems, fix them, and confirm the fix worked in Google Search Console.
What is technical SEO?
Technical SEO makes sure search engines can find every important page on your site, load it, read it and add it to their index. It is how you help search engines find and trust your pages: fast pages, clean URLs, correct redirects and sitemaps, mobile usability, and nothing blocking the crawlers you want.
How is technical SEO different from SEO in general?
Search engine optimization has three parts. Technical SEO looks after the plumbing that gets pages found and loaded; on-page SEO deals with what each page says; off-page SEO deals with links and mentions elsewhere. Every channel that sends people to your site depends on the technical part working.
| Type | Focus | Example |
|---|---|---|
| Technical SEO | Can search engines reach and process the page? | A noindex tag left on a service page after a redesign |
| On-page SEO | Does the page match what people search for? | A title tag that never names the service |
| Off-page SEO | Do other sites trust and mention you? | No credible sites linking to you |
What technical SEO services include
1307 Digital's work covers every layer between your server and Google's index.
| Area | What we check and fix |
|---|---|
| Crawler access | robots.txt, server and CDN rules, and whether AI crawlers like GPTBot, ClaudeBot and PerplexityBot can load pages |
| Indexing | Pages Google has dropped or never indexed, stray noindex tags, duplicate pages |
| Canonical tags | One clear version of each page, so duplicates do not split ranking signals |
| XML sitemaps | Every indexable page listed, with real last-modified dates, and nothing that should not be there |
| Redirects | Broken links, redirect chains, 404s and 301s after a migration |
| Site speed and Core Web Vitals | Speed optimization for loading, responsiveness and layout stability on mobile, which also improves user experience |
| Mobile usability | Responsive layout, tap targets, readable text |
| Rendering | Content hidden behind JavaScript that search and AI crawlers cannot see |
| Structured data | Valid schema markup that tells each search engine what your business, services and FAQs are |
| Site architecture | Internal links and folder structure, so important pages sit close to the homepage and every search engine finds them quickly |
| Security | HTTPS everywhere, mixed-content warnings |
Core Web Vitals: the speed numbers Google measures
Core Web Vitals are three measures of real user experience that Google uses: how fast the main content loads (LCP), how quickly the page responds to a tap or click (INP), and how much the layout jumps around (CLS). Google's published targets are in the table below.
| Metric | Measures | Good |
|---|---|---|
| Largest Contentful Paint (LCP) | Loading speed of the main content | 2.5 seconds or less |
| Interaction to Next Paint (INP) | Responsiveness to taps and clicks | 200 milliseconds or less |
| Cumulative Layout Shift (CLS) | Visual stability | 0.1 or less |
Technical SEO, local SEO, international SEO and digital marketing
Technical SEO supports every other kind of search engine optimization. Local SEO needs fast, mobile-friendly location pages with correct LocalBusiness schema. International SEO needs hreflang tags so each country or language version reaches the right audience, and does not compete with the others.
It also underpins your wider digital marketing and your digital presence, from SEO strategies to content marketing and internet marketing campaigns. Paid ads send visitors to the same pages, content marketing depends on those pages being indexed and ranking in search engine results, and a slow site hurts user experience and conversions across every channel. Strong search visibility starts with a site that search engines can trust. Integrating SEO with design and development from the start costs far less than fixing it afterwards, which is why SEO and web design belong in the same plan: design and SEO decisions affect each other.
Technical SEO for AI search visibility
AI assistants can only cite pages their crawlers can load. Technical SEO for AI search means checking that AI crawlers are allowed, that key content is in the HTML rather than built by JavaScript, and that facts are marked up clearly.
Two technical problems hide AI visibility more often than any content issue:
- Blocked AI crawlers. A 2026 study of 1,046 sites found roughly one in five Cloudflare-hosted sites refusing AI crawlers, usually through a default setting nobody chose. robots.txt can say "allow" while the firewall says "no".
- JavaScript-only content. A Vercel study in December 2024 found the major AI crawlers it observed did not execute JavaScript. Text that your site only builds in the browser is invisible to them, so services, prices and answers belong in the HTML your server sends.
Examples of technical site problems that hold back SEO performance
- A redesign that left the whole site set to noindex
- Two versions of every page (with and without "www", or with a trailing slash) splitting rankings
- Old URLs returning 404 after a migration, with years of links lost
- A sitemap full of redirects and pages that no longer exist
- Product filters creating thousands of near-duplicate URLs
- Hero images so large that mobile pages take seconds to show anything
- A firewall rule quietly blocking ChatGPT's crawler
- Pages missing from search engine results pages because of a stray canonical tag
How 1307 Digital runs technical search engine optimization
- Audit. We crawl the site with professional SEO tools, pull Google Search Console and Core Web Vitals data, and test crawler access, to see how search engines see every page.
- Prioritize. We score each issue on how much it matters and how hard it is, then start where one fix helps the most pages.
- Fix. We make the changes ourselves, or brief your developer with exact instructions, so the optimization reaches the live site.
- Verify. We confirm each fix in Search Console and re-crawl, rather than assuming it worked.
- Monitor. We watch indexing, errors and speed so problems are caught before search rankings and SEO performance drop.
Why technical SEO decides SEO success and SEO performance
Effective SEO depends on the technical foundations first. A great article or a strong backlink is wasted if Google never manages to crawl and index the page it belongs to. That is why our SEO specialists start every project, from a small service site to enterprise-level SEO, with a technical check, and why we only use white-hat SEO methods that keep working after Google updates.
This work is rarely a stand-alone product. At 1307 Digital it sits alongside our other digital marketing services and SEO solutions, including web development services for professional services firms and other clients whose own developer is stretched. One team, one plan, from the server to the search results.
How to choose among technical SEO service providers and SEO agencies in Canada
Many SEO agencies in Canada list it, but far fewer have the technical aspects covered in depth. When comparing technical SEO companies, look for these signs of real expertise in SEO infrastructure:
| Look for | Why it matters |
|---|---|
| They fix, not just report | An audit export does nothing until someone changes the site |
| They verify in Search Console | A fix is only done when Google has re-crawled and accepted it |
| They work with your developers | Most technical changes touch code, hosting or your CMS |
| They check AI crawler access | Search rankings alone no longer cover AI search visibility |
| They explain trade-offs | Good service providers say what not to fix, too |
| They fit your digital marketing and SEO strategies | Technical fixes should serve the pages and keywords that bring revenue |
Most of the top SEO companies and SEO agencies in Canada can describe the work. Lists of the best SEO companies in Canada rarely test SEO knowledge in depth. The best partner is the one whose SEO efforts you can see in your crawl stats and search engine rankings, not the one with the longest list of SEO tools.
How much do technical SEO services cost in Canada?
In Canada, technical SEO consulting typically runs about $100 to $175 per hour, and a one-time technical audit with fixes about $1,000 to $5,000+, depending on site size. Ongoing technical work is usually part of a monthly SEO retainer that also covers content and links, so it supports comprehensive SEO rather than one-off fixes.
Who needs technical SEO, beyond traditional SEO
- Sites whose pages are not showing up in Google, or show up and then disappear
- Businesses planning or recovering from a redesign, platform change or migration
- Large or e-commerce sites with filters, variants and thousands of URLs
- Sites with slow mobile pages
- Businesses that never appear in AI answers despite good content
- Teams whose digital agency left technical debt behind after a redesign
Technical SEO FAQs
What is technical SEO?
Technical SEO covers the parts of a website visitors rarely see, from page speed and sitemaps to redirects, mobile layout and structured data, so search engines and AI crawlers can reach, read and index every important page.
How is technical SEO different from SEO in general?
Technical SEO is the part of SEO that makes pages reachable and loadable for search engines. On-page SEO makes them relevant to searches, and off-page SEO builds the links and mentions that make them trusted.
Can you give me an example of technical SEO?
Fixing a site where every page exists twice, with and without "www", is a technical fix. Adding canonical tags and redirects consolidates the duplicates so ranking signals stop splitting between them.
Do I need coding for technical SEO?
Some technical optimization needs code changes, such as redirects, schema markup and speed fixes. Much of it is diagnosis and settings. 1307 Digital either makes the changes or gives your developer exact instructions.
How long does technical SEO take to show results?
Technical fixes often show indexing and ranking movement within a few weeks, once search engines re-crawl the updated pages. Larger migrations and site-wide fixes can take a few months to settle.
What is a technical SEO audit?
A technical SEO audit is a crawl-based review of a website's infrastructure: crawler access, indexing, redirects, canonicals, sitemaps, speed, mobile usability and structured data, with each issue ranked by impact.
What are Core Web Vitals?
Core Web Vitals are Google's three user-experience metrics: Largest Contentful Paint for loading, Interaction to Next Paint for responsiveness, and Cumulative Layout Shift for visual stability.
What should I look for in technical SEO companies?
Look for companies that fix issues rather than only report them, verify every fix in Google Search Console, work with your developers, and check AI crawler access. Ask for a sample of a past audit and how they prioritized it.
How do I compare SEO companies in Canada for technical SEO?
Ask each of the SEO companies in Canada you are considering to explain one technical fix they made, how they verified it and what changed in rankings. Top technical SEO providers answer with specifics; weaker ones answer with tool names.
Does technical SEO help with AI search?
Yes. AI assistants can only cite pages their crawlers can load and read. Allowing AI crawlers, keeping key content in plain HTML and adding structured data all make a site easier for AI to use.
Should I block AI crawlers in robots.txt?
It depends on your goal. Blocking training crawlers like GPTBot is a business choice, but blocking search crawlers like OAI-SearchBot or ChatGPT-User removes you from live AI answers. Decide deliberately, not by default.
