Technical SEO Agency USA: Professional Audits, Fixes and Core Web Vitals Work Your Developers Can Ship
A technical SEO agency for US businesses whose site is holding rankings back: pages Google has crawled but not indexed, slow Core Web Vitals, JavaScript that hides content, duplicate URLs, broken migrations and structured data that never earns rich results. We run a professional technical SEO audit, prioritize every issue by traffic impact, then either implement the fixes ourselves on WordPress, Shopify and headless stacks or hand your developers tickets specific enough to ship without a follow-up meeting. One-off technical audits in the US run $2,000–$10,000 by site size; ongoing technical consulting sits inside managed engagements from $3,000 per month, month to month. Work is delivered remotely for clients in every US time zone, so “near me” is wherever your team sits.
Who this is for
This page is for US companies that already know, or suspect, that the site itself is the problem: e-commerce stores with thousands of faceted URLs and thin category pages, SaaS companies on React, Next.js or Vue whose content is not rendering for Googlebot, publishers and marketplaces with crawl budget waste, multi-location businesses with duplicate city pages, and any business planning or recovering from a replatform, redesign or domain migration. It is also for marketing teams and agencies that need a technical SEO consultant on call rather than a full retainer.
If you need the content and links as well as the fixes, see managed SEO for US businesses; if you want the audit alone, start with the professional SEO audit USA; for store-specific technical work see e-commerce SEO USA.
The technical SEO problems we are hired to fix
- The problem
Hundreds of pages sit in Search Console as ‘Crawled – currently not indexed’ or ‘Discovered – not indexed’.
How we solve itWe separate quality problems from crawl problems: thin or duplicate pages are consolidated or noindexed, crawl budget is recovered from parameters and faceted URLs, and internal links are rebuilt so the pages that matter are reachable within three clicks.
- The problem
Core Web Vitals are failing on mobile and the last agency’s fix was a caching plugin.
How we solve itWe profile LCP, INP and CLS per template, fix the actual causes (render-blocking scripts, oversized hero images, layout shifts from ads and embeds, slow TTFB) and verify in CrUX field data, not just Lighthouse.
- The problem
Your React, Next.js or Vue site looks fine to users but Googlebot sees an empty shell.
How we solve itWe test rendering with the URL Inspection tool and a headless crawl, then implement server-side rendering, static generation or dynamic rendering per template and confirm indexed HTML matches what users see.
- The problem
A redesign or replatform dropped traffic 30–60% and nobody mapped the redirects.
How we solve itMigration recovery: full old-to-new URL mapping, redirect chains collapsed, canonical and hreflang restored, templates compared against the old versions, and a watch list tracked daily until traffic returns.
- The problem
Duplicate content everywhere: http and https, trailing slashes, UTM and filter parameters, staging indexed.
How we solve itCanonicalization rules, parameter handling, robots directives and host consolidation are set once and documented so the next deploy does not undo them.
- The problem
Structured data is installed but produces no rich results, or triggers manual-action warnings.
How we solve itWe validate Product, Organization, FAQ, Article, LocalBusiness and Breadcrumb markup against Google’s current documentation, remove markup that violates guidelines and track rich-result impressions in Search Console.

Technical SEO pricing in the USA
Technical work is scoped by site size and stack rather than sold as a package: a 200-page WordPress site and a 200,000-URL marketplace need very different audits and fixes. Ranges come from our US SEO pricing guide; our managed engagements start at $3,000 per month. All prices are in USD.
| Engagement | Typical US price | What you receive | Fit for |
|---|---|---|---|
| Free technical SEO check | $0 | Crawl, indexation and Core Web Vitals snapshot with the five issues costing you most traffic | Any US site before committing to an audit |
| Professional technical SEO audit | $2,000–$10,000 by site size | Full audit as above with prioritized fix list, developer tickets and a 90-day roadmap | Sites with unexplained traffic loss or indexing problems |
| Technical fix sprint or migration support | Quoted per project after the audit | Implementation of the audit’s fixes, or migration planning, testing and recovery monitoring | Replatforms, redesigns, Core Web Vitals and rendering fixes |
| Managed SEO with ongoing technical consulting | $1,500–$5,000 per month; median about $3,200; ours from $3,000 | Monthly technical monitoring and fixes alongside content and link work, with revenue reporting | Businesses that want technical SEO owned continuously, not audited once |
Ranges are indicative market figures, not quotes. Your figure depends on competition, site size and how much implementation your team can take on; we confirm it in writing before work starts.
How the engagement runs
- 1Free check and scoping (days 1–3)We run a crawl, review Search Console and Core Web Vitals, and send the five highest-impact issues with a fixed quote for the full audit or sprint.
- 2Technical audit (weeks 1–2)Full crawl, log-file analysis, rendering tests, speed profiling and structured-data validation, delivered as a prioritized list with tickets and effort estimates.
- 3Implementation (weeks 3–6)We ship fixes directly on WordPress, Shopify and most headless stacks, or work through your developers’ sprint with acceptance testing on each ticket.
- 4Verification and monitoring (from week 6)Indexation, Core Web Vitals and rich results are re-measured in Search Console and CrUX; migrations get a 90-day watch, and retainers get monthly technical monitoring.

Technical SEO agency vs full-service agency vs in-house developer
Three ways US businesses handle technical SEO, compared on who finds the problems, who fixes them and who checks that the fix worked.
| Option | Depth of diagnosis | Who implements | Cost structure | Verification |
|---|---|---|---|---|
| Technical SEO agency (this service) | Crawl, logs, rendering, speed and schema audited by specialists | We implement, or write tickets your developers ship | Audit $2,000–$10,000; sprints quoted; consulting inside retainers from $3,000 per month | Re-measured in Search Console and CrUX, tracked to traffic |
| Full-service marketing agency | Technical items usually limited to a tool export | Passed to your developers with little follow-up | Bundled into a $1,500–$5,000 per month retainer | Rarely verified; focus stays on content and rankings |
| In-house developer with an SEO plugin | Fixes what the plugin flags; crawl, log and rendering issues often invisible | Your developer, between feature work | Salary time | Depends on whether anyone owns the Search Console reports |
What we report on technical SEO engagements
- Indexed pages and index coverage by template, against the pages that should be indexed.
- Core Web Vitals pass rate in CrUX field data, mobile and desktop, by template.
- Crawl stats and log-file waste so crawl budget goes to pages that earn revenue.
- Rich-result impressions and valid items from Search Console’s enhancement reports.
- Fixes shipped versus planned with the traffic change attributed to each release.
