Technical SEO + Schema · the foundation

Technical SEO services that make you readable to AI and Google alike.

Schema, crawlability, and entity clarity are what engines read before they rank or cite you. We build the foundation the rest of your visibility stands on.

$3,000 to $6,000, scoped to what your audit finds. 2 to 4 weeks.

AI can't cite what it can't read.This is the layer most agencies skip.

This sits between the audit and a full AI SEO engagement.

If any of these are true, this is the right starting point.

01

Your site is slow, has no schema, and you're not sure why it matters.

Page speed issues, missing structured data, and no llms.txt are quietly costing you both Google rankings and AI citations.

02

Your content is fine. AI engines just can't read it properly.

Good copy doesn't help if the underlying structure blocks crawlers or sends mixed signals about what your business actually is.

03

You've heard you "need schema markup" but nobody's explained what that means.

Schema is code, not content. It's the difference between Google guessing what your page is about and knowing for certain.

04

Your budget is $3,000 to $6,000, and you want the technical foundation done right.

Enough scope to fix what's actually broken, without paying for citation or content work you don't need yet.

What's included
$3,000–$6,000

A full technical audit, schema implementation, and a verification report. 2 to 4 weeks, audit to handover. If you start with the $1,500 audit, it credits toward this engagement.

Foundation's solid, need more?

AI SEO Services builds entity authority and citation engineering on top of a clean technical base. The natural next step once this work is done.

Problem goes deeper than this?

If the issues are structural, not just technical, AI-Ready Website Design rebuilds it properly from page one instead of patching what's there.

The technical problems holding your site back, fixed.

Most sites have at least three critical technical SEO issues they don't know about. Schema gaps, crawlability blocks, and slow Core Web Vitals each hurt your Google rankings, and now your AI search visibility too.

Schema markup

Missing, malformed, or wrong schema is one of the most damaging issues. We fix it across every page so Google and AI engines get a clear signal.

Crawlability & indexation

If Google's crawler can't reach a page, it can't rank it. We find every crawl barrier, robots.txt blocks, stray noindex, broken sitemaps, and fix them.

Site structure & internal linking

Orphaned pages and weak internal linking bleed authority away. We rebuild the hierarchy so your best pages rank and get cited.

Core Web Vitals

LCP, CLS, and INP are Google's page experience signals. We diagnose what's dragging your scores down and fix it at the root.

Duplicate content & canonicalization

Duplicate URLs split your ranking signals. We find every duplicate, set canonicals correctly, and consolidate onto one authoritative version.

Entity clarity

Inconsistent data and vague copy create an unclear entity: lower rankings, and zero AI citations. We make your business unmistakable to engines.

Audit. Fix. Verify. In 2 to 4 weeks.

Every technical SEO and schema engagement runs through three phases. We find what's broken, fix it correctly, and verify the results. No guesswork, no open-ended timelines.

1Week 1

Technical audit

A full diagnostic of everything holding your site back, on Google and in AI search.

  • Technical fixes: robots.txt, sitemaps, redirects, canonicals
  • Core Web Vitals: images, scripts, and layout shifts
  • Internal linking, entity clarity, and llms.txt configured
Delivered: all fixes live, validation confirmed
3Week 4

Verification & reporting

We confirm the work is performing, on Google and across AI engines.

  • AI citation check: how engines read your site post-fix
  • Prioritized next steps and full handover documentation
Delivered: full verification report + 30-min walkthrough call

Nothing about technical SEO changed. Everything about who reads it did.

The signals you built for Google's crawler are now read by ChatGPT, Perplexity, Claude, and Google AI Overviews, and AI engines are less forgiving. Google ranks you lower when something's broken. AI leaves you out entirely.

One engagement fixes them for both audiences. Start with the audit →

Schema markupstructured data

Used to help Google categorize your pages. Now it's the first thing AI reads when deciding whether you're citable.

Crawlabilityaccess & indexation

Used to determine which pages got indexed. Now it decides whether AI engines can see your business at all.

Core Web Vitalsspeed & stability

Used to be a page-experience score. Now it's a trust signal AI engines weigh before quoting you.

Entity claritywho you are

Used to matter for branded searches. Now it decides whether AI knows your business exists to recommend.

A technically clean site that performs everywhere.

Not just fewer errors in Search Console. A site that ranks better on Google, gets cited by AI engines, and earns the trust of every search system that matters.

Ranked.

Pages Google was ignoring start showing up

Crawlability fixes, corrected canonicals, and a clean site structure mean Google can finally index and rank the pages that matter. The content was always there, now Google can find it.

Cited.

AI engines can read, trust, and name you

Schema markup and entity clarity give ChatGPT, Perplexity, Claude, and Google AI Overviews what they need to cite your business confidently, instead of your competitors. llms.txt gets configured too, as routine hygiene.

Fast.

Core Web Vitals in the green

LCP, CLS, and INP fixed at the root, not patched. A fast, stable site earns better rankings, better trust signals, and a better experience for every visitor who lands on it.

Clean.

A technical foundation your team can build on

No more rediscovering the same crawl errors every quarter. A technically sound site with documented schema, a validated structure, and a clear roadmap for what to build next.

AFTER THIS ENGAGEMENT

Technical issues come back. New pages without schema, Core Web Vitals drifting, a sitemap that quietly breaks. AI Visibility Monitoring keeps it monitored monthly instead of waiting for the next audit to find it again.

Technical SEO, answered.

Everything businesses ask before starting a technical SEO engagement. Answered straight.

What does a technical SEO agency actually do?
A technical SEO agency audits and fixes the behind-the-scenes issues that prevent search engines from properly reading, indexing, and ranking your site. That includes schema markup, crawlability, site structure, Core Web Vitals, redirect chains, canonical tags, and internal linking. Foundier also covers the AI-specific layer: entity clarity and the structured data signals that determine whether AI engines like ChatGPT and Perplexity cite your business.
What's included in technical SEO services?
Foundier's technical SEO services run across three phases: a full audit (crawl, schema, Core Web Vitals, indexation, entity clarity, llms.txt status), implementation (fixing every issue found, in priority order), and verification (post-fix crawl, schema validation, Core Web Vitals retest, AI citation check). Every engagement is 2 to 4 weeks with a final verification report and 30-minute walkthrough call.
Should I get Technical SEO + Schema or AI SEO Services?
They're sequential, not competing. Technical SEO + Schema fixes the infrastructure: crawlability, schema, Core Web Vitals, entity clarity, the things that determine whether AI engines can read your site at all. AI SEO Services builds on top of that: content restructuring, citation engineering, and entity authority work that gets you actually named in AI answers. Technical SEO comes first, then AI SEO Services once the foundation is solid.
How is technical SEO different from regular SEO?
Regular SEO is a broad term that covers content, keywords, backlinks, and technical health. Technical SEO specifically covers the infrastructure layer: how your site is built, structured, and read by search engines. It's the foundation everything else sits on. Without strong technical SEO, the best content in the world won't rank, because search engines can't access, understand, or trust it.
Do I need a technical SEO consultant or can I do it myself?
Some technical SEO tasks are manageable with a good tool: Screaming Frog, Ahrefs, Google Search Console. But diagnosing the root cause of crawlability issues, implementing correct JSON-LD schema for every page type, and fixing Core Web Vitals at the code level require specialist knowledge. Businesses that try this themselves often fix the symptoms and miss the underlying issues.
How long does technical SEO take to show results?
Most technical SEO fixes, crawlability, schema, redirects, are indexed by Google within 2 to 4 weeks of implementation. Core Web Vitals improvements typically show in Google Search Console within the same window. AI citation improvements can show faster, because AI engines re-index more frequently than Google. A full engagement with Foundier runs 2 to 4 weeks of active work, with measurable changes visible within 30 days post-implementation.
What is schema markup and why does it matter?
Schema markup is structured data: code added to your pages that tells search engines and AI engines exactly what your content is about. It's the difference between Google guessing that your page is about a service and knowing it, with the business name, service type, location, and pricing clearly defined. For AI search, schema is even more critical. It's the primary signal ChatGPT, Perplexity, and Google AI Overviews use to decide whether your business is citable.
How does technical SEO affect AI search visibility?
AI engines use the same technical signals as Google, schema, crawlability, entity clarity, to decide who to cite in their answers. A site with broken schema, crawl blocks, or vague entity signals is invisible to AI engines even if it ranks on Google. Technical SEO is now the foundation of AI visibility. Foundier's technical SEO services are built with both Google and AI engines in mind from the start.
What's the difference between technical SEO and on-page SEO?
Technical SEO covers infrastructure: how your site is built, crawled, and indexed. On-page SEO covers content: keywords, headings, copy, internal links. Both matter, but technical SEO comes first. If your site can't be crawled and indexed correctly, on-page optimization has no foundation to sit on. Foundier's technical SEO services fix the infrastructure layer; once that's clean, on-page and AI SEO work is far more effective.
Do I need technical SEO if my site already ranks on Google?
Ranking on Google doesn't mean your technical SEO is clean. It means Google is working around your issues well enough to rank some pages. Most ranking sites still have schema gaps, crawlability inefficiencies, and Core Web Vitals problems costing them positions they don't know they're losing. And ranking on Google is now separate from being cited in AI search: you can rank well and be completely invisible in ChatGPT and Perplexity.
What is llms.txt and do I actually need one?
llms.txt is a standard, similar in spirit to robots.txt, meant to tell AI crawlers what your site is about. In practice, independent research has found the vast majority of llms.txt files get effectively zero traffic from AI retrieval bots today, and Google has described it as a coding-agent convenience rather than a search signal. We still configure it correctly as routine technical hygiene, since it costs nothing to do right, but the real signals AI engines weigh when deciding who to cite are schema, entity clarity, and structured content, not this one file.

Fix the technical foundation. Win Google and AI search.

Whether you need a full technical SEO audit or you already know what's broken, Foundier fixes it correctly, verifies the results, and hands over a site that performs everywhere.

This is the technical layer behind AI search optimization services: a site that can be crawled, understood, and trusted by Google and AI engines.
