Technical SEO Services & AI Search Visibility, Run by Engineers
Our technical SEO services are an add-on for software, SaaS, ecommerce and enterprise platforms, run by engineers. We fix crawling, indexing, rendering, Core Web Vitals, structured data and migrations at the code level, and we structure content so AI search answers can cite it. Work starts with a technical SEO audit that also shows where your brand appears in AI answers today. This service is built for complex platforms. It is not a local or small-business SEO package.
Technical SEO Services We Provide
Technical SEO is the work that decides whether search engines can crawl, render, understand and index a site: the code, templates, architecture and data behind the pages. Our technical SEO services cover that work and ship it as engineering changes.
Technical SEO at Scale
Crawl and index management, rendering, architecture, internal linking, faceted navigation control, log file analysis, structured data and Core Web Vitals. We deliver it as engineering work, so we can ship the changes as well as specify them.
Migration SEO
For replatforms, domain moves and IA changes we handle the URL inventory, one-to-one redirect mapping, parity testing, cutover and monitoring. Success is measured in traffic.
Ecommerce and Programmatic SEO
Category and product architecture, faceted navigation, and template systems that produce useful pages at scale instead of redundant URLs.
International and Multi-Locale SEO
We set up hreflang and regional architecture, and plan content strategy market by market.
Answer Engine Optimization (AEO / GEO)
Structuring content for extractable meaning: clear question-and-answer format, entity clarity, schema and source credibility, plus monitoring of where you appear across answer surfaces.
Supporting Work
Technical fixes go further when the content and measurement around them are sound. On the content side we set up topic architecture and content models that match how your information actually changes, along with editorial processes, briefs and quality standards that last beyond one sprint. Keyword and demand research maps head and long-tail demand to your architecture and content plan. We also do digital PR and authority building: coverage and third-party citations, which matter more now that an algorithm chooses what to cite. Measurement runs through Search Console, GA4, rank tracking and share of voice, and ties back to revenue and pipeline.
Getting Cited by the Systems Answering the Question
A ranked list shows pages. An answer engine writes a summary and cites a few sources. Our AI SEO services work on the signals that make a page citable:
On the page
Extractable Structure
A clear question-and-answer format lets an engine cite your content with confidence.
Entity Clarity
We define what your content is about, so engines can match it to the right searches.
Schema and Structured Data
A machine-readable set of facts engines can use directly.
Around the page
Source Credibility
Named sources in your content let engines verify claims and cite you.
Freshness
For queries where timing matters, engines look for signs that your content is current.
Monitoring
Answer engines are black boxes, so we track whether you appear in answers for your target queries.
Who This Is For
Technical SEO is an add-on to our engineering work, so it fits teams whose search problems sit in the code.
If you run a local business and need map-pack rankings, review management or a monthly local SEO package, we are the wrong fit. That work is better served by a local SEO specialist.
-
Large platforms
Large platforms are the obvious case. At 200,000 URLs, page-by-page fixes stop scaling, and templates, internal linking and crawl budget decide what Google indexes.
-
Migrations
Teams planning a migration also come to us, because a replatform, domain move or information-architecture change needs URL mapping, redirects and post-launch monitoring before cutover.
-
Rendering-heavy sites
Some sites depend on rendering for what Google can read at all. We check what crawlers receive and fix it in the application.
-
Stuck audits
If your SEO audit has been stuck in the backlog, our engineers can ship the fixes themselves.
-
SEO agencies
And if you're an SEO agency that needs a technical partner, you keep the strategy while we handle the technical work.
Technical SEO for SaaS, Ecommerce and Enterprise Sites
SaaS and Software Companies
SaaS sites usually split into a marketing site, documentation, signup flows and the app itself, often on different stacks. We check what crawlers receive from JavaScript-rendered pages, keep the app out of the index where it doesn't belong, and make docs and templates crawlable. If you are building the product too, our SaaS development services team can plan rendering, URLs and metadata into the build.
Ecommerce Platforms
Here the work is category and product architecture, faceted navigation that doesn't spawn millions of crawlable URLs, and product templates that stay useful at scale. When the fix belongs in the platform, our ecommerce development company team can build it.
Enterprise and Multi-Locale Sites
These sites have large URL counts, often several markets or languages, and migrations that have to keep traffic. Our enterprise SEO services start with hreflang, regional architecture, template-level fixes and migration plans. For rebuilds of the site itself, see our web development services.

Run by Engineers Who Ship the Fixes
Whether SEO work turns into results depends most on who ships the changes, which is why our estimate form asks about it.
Recommendations → your backlog → maybe next quarter
When your technical SEO company also writes production code, a fix to rendering, routing, templates or redirects can go straight into the application instead of joining a backlog.
If your developers have a roadmap, we write the work so they can pick it up.
If they can't get to it, we ship it ourselves.
If you already have an SEO agency, we act as its technical partner: the agency keeps the strategy and we handle the technical work.
Vortex builds software, SaaS platforms, web applications and ecommerce systems.
Either way, the engineers on your first call are the ones who do it.
Technical SEO Audit Services
A technical SEO audit checks whether search engines and AI systems can crawl, render and index the pages that matter, and finds what in the code, templates or architecture is stopping them. On a large platform it matters because the problems above (crawl waste, unrendered content, a risky migration) are invisible from the page itself and expensive once traffic has already dropped.
Crawl, index and rendering
Our technical SEO audit services start with crawl and index management, including log file analysis, and with rendering: what crawlers actually receive from your application.
Architecture, data and Core Web Vitals
From there we look at site architecture, internal linking and faceted navigation, then structured data and Core Web Vitals.
Migration risk
If a replatform or domain move is planned, we assess the migration risk.
International setup
Where you run more than one market, we check the international setup and hreflang.
Content, authority and AI answers
We review content and authority alongside the technical findings, and check which AI answers cite your brand today for your priority queries.
Report and tickets
The audit ends in a written report and a prioritized list of fixes written as engineering tickets, ready for your developers (or ours).
