Technical SEO services
Technical SEO services for websites and web applications: crawling and rendering fixes, structured data, page speed, migrations that keep their URLs and visibility in AI search, with dedicated SEO specialists for your team or a defined SEO project.
SEO work we provide
Technical SEO audit
Crawling, indexing, rendering, redirects, canonical tags and internal links checked across the whole site, delivered as a written list of issues ordered by impact.
Rendering for search engines
Single-page applications in Angular, React or Vue moved to server rendering or prerendering, so crawlers receive complete HTML on the first request instead of an empty shell.
Structured data
Schema.org markup in JSON-LD for the organisation, services, products, articles and FAQs, generated from the same data as the page so the two cannot disagree.
Page speed for search
Images, fonts and third-party scripts trimmed until the Core Web Vitals pass on field data from real visitors, not only on a lab score.
Redesigns and replatforming
Every old URL mapped to its new address with a permanent redirect, tested before launch and watched in Search Console afterwards, so a move keeps the links the old site earned.
AI search and indexing
Robots rules for AI crawlers, an llms.txt file, sitemaps generated from the route list and IndexNow submission on deploy, so Bing and the other search engines that support IndexNow hear about a page when it goes live.

What technical SEO can and cannot do
Technical SEO makes sure search engines and AI assistants can find, render and understand every page. Rankings also depend on content, links and competitors, so we promise none; we report the measures the work moves: pages indexed, errors cleared, Core Web Vitals passed, and impressions and clicks in Search Console.
This site is the worked example. It is prerendered, carries structured data on every page, publishes an llms.txt file, notifies search engines through IndexNow on every deploy, and runs no tracking scripts under a strict content security policy. The same checks can run in your pipeline, so a release that breaks rendering fails before it ships.

Questions about SEO
Can you guarantee first-page rankings?
No, and nobody can honestly do so: rankings depend on the search engines, your competitors and your content as well as the site. What we commit to is the technical work and the measures behind it, tracked in Search Console from the first week.
Our site is a single-page application. Can it rank?
Yes, once crawlers receive real HTML. We add server rendering or prerendering in Angular, Next.js or Nuxt, or a prerendering step for older stacks, and confirm the result with the search engine’s own URL inspection rather than assuming it.
Do you work on visibility in AI assistants?
Yes, as far as a site controls it: crawler access in robots.txt, an llms.txt file, structured data, and pages that each answer one question in plain HTML. Which sources an assistant cites is its own decision, so we measure the result rather than promise it.
How quickly can SEO specialists start?
When the right SEO specialist is available, the start is gated only by your interview and the NDA and IP assignment. Otherwise we run a search, which typically produces candidate profiles within two to three weeks, and nobody starts until you have said yes.
How do we hire SEO specialists through BigTree108?
Tell us the work, the seniority and the hours you need. We propose one or two people with their profiles, you interview them the way you would interview your own hire, and you sign one agreement with BIG TREE 108 LLC and receive one invoice a month.
Who owns the work they produce?
You do. Every specialist has a signed contract with BigTree108 that assigns all work product to the company, and our agreement with you assigns it onward. Code, designs and documents are delivered into your own repositories and tools, not kept where only we can change them.
Is your site hard to find?
Send the address and what you want it to be found for. You get an answer within one business day: the first technical issues we see and a plan to fix them.
