Technical SEO
We audit and fix your website's technical foundation so search engines can crawl, index and display it properly: speed, Core Web Vitals, structured data, sitemaps, languages, accessibility and migrations.
Technical SEO is the work on a website's structure and code that lets search engines crawl it, understand it, index it and serve it quickly. It isn't about what to write, but about making sure what's written reaches the index without obstacles. At AVILA®, a technology and business consulting firm based in Monterrey, Mexico, we build it into every site we develop and offer it as an audit and fix service for existing sites.
How is it different from content SEO and LLM optimization?
Search visibility has three layers that work together:
Technical SEO: the site can be crawled, loads fast, is well structured and error-free. That's this service.
Content SEO: which topics to cover, with which terms and in how much depth. Our sister company tresensocial handles it as part of digital presence.
LLM and AI search optimization: making sure assistants such as ChatGPT, Gemini or Claude understand your site and cite it in their answers. It builds on technical SEO but has its own practices.
Great content on a slow or poorly indexed site underperforms. A technically flawless site without useful content does too. That's why we keep these services separate but coordinated.
What we audit and fix
Crawling and indexing
We review robots.txt, meta robots tags, server response codes, redirect chains, orphan pages and broken links. In Google Search Console and Bing Webmaster Tools we confirm which pages are indexed, which aren't and why.
Speed and Core Web Vitals
Core Web Vitals are the metrics Google uses to measure loading experience: how long the main content takes to appear (LCP), how quickly the page responds to an interaction (INP) and how much the layout shifts while loading (CLS). We improve them with modern, correctly sized image formats, lazy loading, less third-party code, caching and the right hosting.
Structured data (schema.org)
We mark up in JSON-LD what each page is: the organization, its services, articles, FAQs, products or events. That way search engines understand the content without guessing and can show rich results.
Sitemaps, canonicals and duplicate content
An up-to-date XML sitemap tells search engines which pages exist and when they changed. The canonical tag points to the main version of a page when variants exist (filters, parameters, with and without "www"), so they don't compete with each other.
Multilingual sites (hreflang)
Hreflang tags connect each page with its version in another language, so a visitor in Mexico sees the Spanish page and one in the United States sees the English page.
Accessibility
Headings in order, alt text on images, sufficient contrast and properly labeled forms. Accessibility under the WCAG guidelines helps people with disabilities and also helps search engines understand the page. For an in-depth review, see UX and accessibility assessment.
Security and core signals
HTTPS across the whole site, a solid mobile version, unique titles and descriptions, readable URLs and an internal linking structure that gets visitors to important pages in a few clicks.
Migrations without losing rankings
Changing platform, domain or design is the riskiest moment for search visibility. Here's how we keep it under control:
Inventory of every current URL and of those that get traffic and external links.
A map of permanent (301) redirects from each old URL to its new equivalent.
Checks on staging for titles, structured data, canonicals and speed before launch.
Launch with the new sitemap submitted to Search Console and Bing.
Monitoring of crawl and indexing errors in the following weeks, with immediate fixes.
How we work
Audit. A full crawl of the site, a Search Console review and speed measurements on mobile and desktop.
Prioritized report. Issues ranked by impact and effort, explained in plain language.
Fixes. If we built the site or have access, we make the changes; if not, we give your team precise instructions.
Verification. We measure again and confirm in Search Console that the changes were picked up.
Follow-up. Periodic reviews under a support plan, because every update can break something.
Experience behind the service
Technical SEO is part of every website we build: in 2015 we delivered a self-managed WordPress site with SEO, and in 2025, corporate WordPress sites with technical SEO. In 2026 we delivered a redesign with a migration to WordPress and a corporate site with a newsroom built for search engines and AI assistants. Our own site runs on WebLayer, the website engine we developed at AVILA®, which includes a sitemap, structured data, linked Spanish and English versions and an llms.txt file.
Benefits
- A clear diagnosis of why your site doesn't show up or loads slowly, ranked by impact.

- A better loading experience on mobile, where many of your visitors browse today.
- Structured data that helps search engines and AI assistants understand your organization.
- Migrations and redesigns planned to keep the rankings you've already earned.

Frequently asked questions
What is technical SEO?
It's the part of SEO that deals with a site's structure and code: making sure search engines can crawl and index it, that it loads fast, that it's properly marked up with structured data and that it's free of errors such as broken links, duplicate content or redirect chains. It's the foundation that content and AI search optimization rely on.
How long until technical SEO shows results?
Fixes to serious issues, such as blocked or unindexed pages, usually show up once the search engine recrawls the site, which can take days or weeks. Speed and structure improvements show up gradually. Nobody can guarantee a specific position on Google; what we can make sure of is that nothing technical stands in your way.
What are Core Web Vitals and why do they matter?
They are three Google metrics for loading experience: LCP, how long the main content takes to appear; INP, how quickly the page responds to a tap or click; and CLS, how much the layout shifts while loading. They're part of Google's page experience signals and, above all, they affect whether visitors stay.
Do I need Google Search Console?
Yes. It's Google's free tool to see which pages are indexed, which errors the search engine finds, which queries your site appears for and how many clicks it gets. We set it up, verify ownership and submit the sitemap. We do the same in Bing Webmaster Tools, because Bing also feeds several AI-powered search assistants.
Can you do technical SEO on a site you didn't build?
Yes. We start with an audit and a prioritized report. If you give us access to the site, we make the fixes; if another provider maintains it, we give your team precise instructions. Some closed platforms limit what can be changed, and we tell you so in the audit.
Does technical SEO include writing content?
No. Technical SEO gets the site ready for content to perform. Content strategy and copywriting are handled by tresensocial, our sister company, or by your own agency. We do review the technical side of content: titles, descriptions, headings, internal links and structured data.
What happens to my rankings if I switch platforms?
If the migration isn't planned, you can lose rankings because pages disappear or redirects are done wrong. We prevent that with a URL inventory, a 301 redirect map, pre-launch testing and Search Console monitoring in the weeks that follow. It's the most delicate part of a redesign, and we treat it that way.
