Technical SEO services fix the infrastructure that decides whether your pages can rank: crawlability, indexation, site architecture, Core Web Vitals, canonicalization, and structured data. Foundgrove audits and remediates these — plus JavaScript rendering and AI-crawler access — so Google, ChatGPT, and AI Overviews can find, render, and trust your site. Pricing starts at $2,500/mo, month-to-month.

Technical SEO Services
The foundation every ranking sits on. We fix crawlability, indexation, site speed, and structured data so your content can actually rank — in Google and AI search.
Definition
What is technical SEO?
Great content cannot rank on a broken foundation. Our technical SEO audit works through the full checklist — crawl budget, index bloat, redirect chains, canonicalization, robots.txt and XML sitemaps, mobile-first readiness, HTTPS and security headers, Core Web Vitals, structured data, log files, JavaScript rendering, and hreflang — then we remediate the highest-leverage issues first. Increasingly, technical SEO also means being machine-readable for AI: clean semantic HTML, complete schema, and an llms.txt so crawlers like GPTBot, ClaudeBot, and PerplexityBot can parse and cite you. We fix these at the code level, then verify with field data in Google Search Console.
Fix what blocks rankings
We find and remediate the crawl, index, and rendering issues that silently cap your visibility — the problems content and links can never overcome on their own.
Core Web Vitals in the green
We diagnose and fix LCP, INP, and CLS at the code level — render-blocking scripts, image optimization, layout shift — so speed stops costing you rankings and conversions.
Machine-readable for AI
Complete schema, clean semantic HTML, and llms.txt configuration so AI crawlers and Google's systems can parse, extract, and cite your content accurately.

Our technical SEO audit: the full checklist
The audit works through every layer that affects whether a page can rank, then prioritizes fixes by impact and effort so you are not handed a flat 200-item list. It covers the crawl, index, rendering, speed, structure, and machine-readability of your site.
- Crawlability — crawl budget, robots.txt, XML sitemaps, orphan pages
- Indexation — index bloat, noindex/canonical conflicts, coverage errors
- Redirects & canonicals — chains, loops, and duplicate-content consolidation
- Core Web Vitals — LCP, INP, and CLS measured on field data
- Rendering — JavaScript hydration and crawlability of JS-heavy pages
- Structure — site architecture, internal linking, and hreflang
- Machine-readability — schema, semantic HTML, and llms.txt for AI crawlers
Crawlability & indexation
If Google cannot crawl a page, or chooses not to index it, nothing else matters. We optimize crawl budget, clean up index bloat and coverage errors, fix robots.txt and XML sitemaps, and use log file analysis to see exactly how search bots move through your site — the one signal only real server logs reveal.
JavaScript rendering for JS-heavy sites
React, Next.js, and other SPA frameworks can hide content from crawlers if rendering and hydration are not handled correctly. We diagnose what Googlebot actually sees, fix client-only content that never gets indexed, and confirm the rendered HTML matches what users get.
Canonicalization & duplicate-content fixes
Parameter URLs, pagination, and near-duplicate pages split ranking signals and waste crawl budget. We set correct canonical tags, handle parameters and pagination, and consolidate duplicates so authority concentrates on the URL you actually want to rank.
Hreflang & international technical SEO
For multi-country or multi-language sites, hreflang tells Google which version to show which audience. Misconfigured hreflang makes the wrong pages rank in the wrong markets. We implement and validate country and language targeting and resolve geo-duplication — a gap most competing pages do not even cover.
Migration-safe technical SEO
A replatform or URL change can erase rankings overnight without a redirect plan. We map every old URL to its new destination, preserve canonical and internal-link parity, and QA indexation and Core Web Vitals before and after launch so you keep the equity you have built.
Recovering from traffic drops & manual actions
When traffic falls off a cliff, the cause is usually an algorithmic shift, a manual action, or a botched migration. We diagnose which one, isolate the affected URLs and queries, and build a remediation plan rather than guessing at random fixes.
Technical SEO for AI & LLM crawlers (GEO)
AI answers increasingly decide who gets found, and they depend on machine-readability. We make sure AI crawlers like GPTBot, ClaudeBot, and PerplexityBot can access your content, configure llms.txt, and complete the schema so ChatGPT and Google AI Overviews can parse and cite you accurately.

Technical SEO vs on-page SEO — and the 4 types of SEO
Technical SEO is about access and infrastructure — can engines crawl, render, and index the site. On-page SEO is about relevance — content, titles, headings, and internal links for a query. Off-page SEO is authority (backlinks). The emerging fourth type, AI/answer-engine optimization, makes content citable by LLMs. Technical SEO is the foundation the other three sit on.
Technical SEO for SaaS & ecommerce sites
SaaS and ecommerce sites hit technical SEO problems at scale: JavaScript-rendered app content, faceted-navigation crawl traps, near-duplicate product and collection pages, and pagination. Fixing these is often the highest-leverage growth lever a scaling site has.
Technical SEO pricing
Foundgrove handles technical SEO inside our SEO retainer starting at $2,500/mo, or as a focused technical engagement scoped to your site's size and issue backlog. Either way it is month-to-month, no minimum, no lock-in — and Core Web Vitals, crawlability, indexation, and schema are fixed in-house rather than billed separately or passed to your developer.

FAQs
Common questions about technical seo.
What are technical SEO services?
Technical SEO services optimize the infrastructure of your website so search engines and AI crawlers can find, render, and index your content. That includes crawlability, indexation, site speed and Core Web Vitals, URL and architecture structure, canonicalization, and structured data. It is the foundation layer — without it, even excellent content and strong backlinks underperform because engines cannot fully access or trust the site.
How do I know if I need technical SEO?
Common signals include pages that are not indexed, traffic that plateaued despite publishing content, slow load times or failing Core Web Vitals, a site migration that lost rankings, or rich results that stopped appearing. A technical SEO audit surfaces these issues and quantifies their impact, so you fix the highest-leverage problems first instead of guessing.
How much do technical SEO services cost?
Foundgrove handles technical SEO inside our SEO retainer starting at $2,500/month, or as a focused technical engagement scoped to your site's size and issue backlog. We fix Core Web Vitals, crawlability, indexation, and schema in-house rather than billing them separately or passing them to your developer. Engagements are month-to-month with no minimum and no lock-in.
Do you fix Core Web Vitals?
Yes, at the code level. We diagnose LCP, INP, and CLS failures — render-blocking scripts, unoptimized images, layout shift, slow server response — and remediate them, then verify with field data. Core Web Vitals are a confirmed ranking signal and a conversion factor, so we treat them as core technical SEO work rather than an optional add-on.
What are the 4 types of SEO?
The four types of SEO are commonly described as technical SEO (crawlability, indexation, speed, and structured data), on-page SEO (content, titles, headings, and internal links), off-page SEO (backlinks and authority), and increasingly a fourth — AI or answer-engine optimization (GEO/AEO), which structures content so ChatGPT, Perplexity, and Google AI Overviews can cite you. Technical SEO is the foundation the other three depend on.
What is the difference between technical SEO and on-page SEO?
Technical SEO makes sure search engines and AI crawlers can access, render, and index your site — crawl budget, canonicals, Core Web Vitals, JavaScript rendering, and schema. On-page SEO optimizes what is on the page for a specific query — content depth, titles, headings, and internal linking. They overlap on structured data, but technical SEO is about access and infrastructure while on-page SEO is about relevance and content.
Does a site migration need technical SEO?
Yes — a replatform or URL change is one of the highest-risk moments in SEO. Without careful 301 redirect mapping, canonical parity, and pre- and post-launch QA, a migration can quietly drop rankings and traffic that take months to recover. Migration-safe technical SEO maps every old URL to its new destination and verifies indexation, internal links, and Core Web Vitals after launch.
