How a technical SEO engagement runs
How a LASEO technical SEO engagement runs
Six phases. Each one ends with something fixed in your website or visible in Google, not a slide. No secret method you cannot continue without us.
- 01
How Google visits your site (weeks 1-2)
We go through 30-90 days of your server logs: the record of every visit by Google, Bing and AI tools like ChatGPT. That shows which pages Google actually visits, which ones it ignores, and where it wastes time on filter pages, internal search results and other pages that should never rank.
- 02
Full site scan and structure check (weeks 2-3)
We scan your entire site and map every duplicate page, language version, redirect chain and paginated list. The result is a prioritised list of fixes, each with the steps to reproduce the problem and the exact place in your website where it needs to change.
- 03
Rich results setup (weeks 3-5)
We add structured data to your page templates: code that tells Google what a page is about, so it can show stars, prices and breadcrumbs in the search results. Products, articles, FAQs, reviews and your company details. Everything is tested with Google's own tools and monitored in Google Search Console.
- 04
Core Web Vitals fixes (weeks 4-8)
Core Web Vitals are Google's scores for how fast a page loads, how quickly it responds and whether the layout jumps around. We measure them per page type with real visitor data, then remove what slows you down: heavy scripts, oversized images, slow fonts and third-party tools. Every fix is tested on real phones and laptops.
- 05
Making sure Google can read every page (weeks 6-10)
On websites that lean heavily on JavaScript, Google often sees an empty or half-loaded page. We check what Google actually sees and change how your pages are built, so the content is there from the first load. That works whatever your site is built on, from Shopify to a custom platform.
- 06
Ongoing monitoring (every week)
Every week we scan your site again and compare it with the week before. You get an alert in Slack when pages start returning errors, duplicates appear, language versions break or rich results disappear. Every month you get a technical health score with your report.
Think of us asyour part-time head of technical SEO.
We sit between your developers and your marketing team. Every month we check how Google moves through your site. We stop duplicate pages from competing with each other, test your rich results after every website update and track speed for every page type, not just the homepage. The role most agencies promise but never actually carry out.
What our technical SEO clients say
Technical SEO in their own words
Our technical foundation was full of small mistakes we never spotted, from duplicate canonicals to broken hreflang. LASEO cleaned it up and pagination finally behaves.
LASEO cleaned up the crawl paths on our site and got variant and colour-option indexing in order. GSC reflected it quickly.
We thought our stack was technically clean until LASEO audited it and surfaced plenty of wasted crawl paths. After the fix the right pages get indexed.

Google and AI search
Found in Google, and in the answers AI gives
More and more buyers ask ChatGPT, Perplexity or Google's AI Overviews before they click on anything. We make sure your brand shows up there too: as a source AI quotes and a brand it recommends.

Honest answers about technical SEO
The questions we hear most before a technical SEO engagement starts.
About LASEO
Question not listed?
A senior specialist is happy to answer it. Request your free audit, or call us directly.
Ask three questions. First: will the person running my account make the changes in my website, or only hand over advice? If it is only advice, you are buying an audit, not the work. Second: do you look at server logs, the record of every Google visit, or only at a scan of the site? The logs show where Google wastes its time. Third: do you measure speed per page type, or one score for the whole site? One overall score hides the pages that are slow. An agency that cannot answer these clearly is selling standard technical SEO.
On-page SEO is what visitors see on the page: the title, headings, text, internal links and image descriptions. Technical SEO is the foundation Google uses to reach and read that page: which pages it may visit, which version of a page counts, the sitemap, language versions, how the page is built and how fast it loads. Same site, two layers. On-page work improves single pages. Technical fixes improve whole page types at once, sometimes thousands of pages in one go. Most sites need both, but technical SEO matters most when Google cannot properly find or read your pages.
Technical SEO does not push rankings up by itself. It removes what is holding your content back. If Google is not allowed to visit a page, cannot read it, cannot tell which version is the real one or finds it too slow, no amount of content work will make it rank. Once those blocks are gone, your content and links do the ranking. Think of technical SEO as the foundation: invisible when it works, very costly when it breaks. Fix the foundation first, then invest in content.
Run one before you move to a new platform or domain, after a migration if you skipped the first one, when organic traffic drops without a clear content reason, when Google Search Console shows pages dropping out of the index, before a major Google update if your last audit is more than six months old, or once a year as a check-up. Outside those moments an audit rarely pays off, unless something changed on your website. The audit itself is worth little. The list of fixes it produces is worth everything, so make sure the agency you hire actually carries them out.
Screaming Frog and Sitebulb to scan websites, with custom checks for duplicate pages, language versions and structured data. A log analyser to see how Google actually visits your site. Google Search Console and Google's own testing tools to check what Google can read. Lighthouse, WebPageTest and real visitor data from Chrome for page speed. Ahrefs for a second opinion and Google Analytics to connect it all to traffic. The tools are standard. What matters is a senior specialist who knows what the data means.
