An audit is only as good as the fixes that follow.
Most technical SEO audits end as a spreadsheet nobody acts on. Ours end with the fixes made. Our in-house SEO team crawls every page the way Google does, checks which pages are indexed and which Google quietly left out, measures speed and Core Web Vitals on the templates that matter, and reviews titles, headings, structured data, internal links and redirects across the whole site. Every issue is ranked by the traffic and revenue it puts at risk, so the first fixes are the ones that move rankings, not the easiest ones to tick off. Then we fix them, on WordPress, Shopify, Magento and custom sites, or write clear tickets for your developers, and re-crawl to confirm each one is gone. Your Client Hub keeps crawling the site and shows the rankings, organic traffic and leads that follow, so the audit keeps paying off long after the first report.
Technical SEO for your business, whatever your site runs on.
Stores, service businesses, practices, law firms, manufacturers and dealers all break in different places. Each already has sites we have audited, fixed and grown.
Online stores Make every product findable.
Stores lose rankings to duplicate variants, faceted URLs, thin category pages and products Google never indexes. A technical audit finds where the catalog leaks crawl budget and which templates hold whole sections back. We fix canonicals, filters and pagination in the templates, clean up metadata and headings across categories and products, and track organic revenue and orders in your Client Hub.
Ecommerce SEOHome services Show up when the job is urgent.
Plumbers, roofers, HVAC and cleaning companies win on fast, crawlable service and location pages. Slow mobile pages, broken forms and duplicate city pages cost calls every day. We speed up the pages people land on from their phones, fix indexing and duplicate location pages, add the structured data Google uses for local results, and track calls and form leads in your Client Hub.
Home Services Marketing
Medical & healthcare Earn trust before the first visit.
Practices and clinics need service and condition pages Google can crawl and trust, on sites that are fast and accessible. Technical problems quietly keep good content from ranking. We fix crawl and indexing issues, speed and mobile layout problems, add medical structured data where it fits, and track appointment requests and calls in your Client Hub.
Healthcare MarketingLaw firms Rank the practice areas that pay.
Law firm sites grow into hundreds of practice, location and blog pages that compete with each other. An audit shows which pages Google ignores and what keeps the valuable ones from ranking. We untangle duplicate and competing pages, fix indexing and internal links toward the practice areas you want, and track consultations and calls in your Client Hub.
Law Firm Marketing
Manufacturers & B2B Get found by spec and application.
Industrial and B2B sites carry deep catalogs, PDFs and spec pages that search engines struggle to crawl. Buyers searching by part and application never find them. We restructure category and product templates, fix crawl and indexing gaps, clean up metadata at scale and track RFQs and calls in your Client Hub.
Manufacturing Marketing
Automotive Keep inventory and model pages ranking.
Dealer and parts sites churn thousands of inventory and product pages. Crawl errors, indexing gaps and slow templates keep model and part searches from finding them. We fix what inventory and catalog feeds break, tighten title and heading structure on model and part pages, and track leads, calls and sales in your Client Hub.
Automotive Marketing
Everything a technical SEO audit covers, fixed, not just flagged.
The checks behind our technical SEO audits and fixes for 1,100+ sites in the last three years, with schema added for 150+ and redirect maps for 300+: crawling, indexing, speed, on-page structure, structured data and links, fixed in the order that moves rankings first.
Crawl & indexing
If Google can’t crawl a page, it can’t rank it. We crawl every URL the way Google does, check your sitemaps and Search Console coverage, and find the broken links, redirect chains, blocked resources, duplicate and orphaned pages that keep your best content out of the index. Then we fix them and re-crawl to confirm.
Speed & Core Web Vitals
Slow pages lose visitors before they load and lose ground in Google’s page experience signals. We measure load time and Core Web Vitals on the templates that carry your traffic, then fix the heavy images, scripts, fonts and hosting issues behind them, so pages feel instant on a phone.
On-page structure
Titles, meta descriptions, headings and internal links tell Google what each page is about and which pages matter most. We fix missing, duplicate and competing tags across every template, rebuild heading hierarchy and point internal links at the pages you want to rank.
Structured data & AI search
Structured data helps Google show rich results and helps AI assistants understand exactly what you offer. We add and validate schema for your business, services, products, reviews and FAQs, so your pages are ready for rich results, AI Overviews and ChatGPT answers.
Backlink health check
Every audit checks your backlinks four ways: links other sites removed, links still pointing at pages that no longer exist, links that could hurt you, and dead ends on your own pages. We reclaim what you have earned, redirect what’s broken and flag risky links, and the check refreshes monthly on every SEO account.

Technical SEO audit questions, answered
A page-by-page check of everything that affects how search engines crawl, index and rank your site: crawl errors, indexing gaps, redirects, speed and Core Web Vitals, mobile layout, titles and headings, structured data, internal links and backlinks. The output is a prioritised list of fixes, and with us, the fixes themselves.
A ranked list of issues, each with the pages it affects, why it matters and what it puts at risk, plus a plan for fixing them. Our team then makes the fixes, or writes clear tickets for your developers, and re-crawls to confirm each one is resolved.
We fix them. Our SEO team and in-house developers work on WordPress, Shopify, Magento, BigCommerce and custom sites. If you have your own developers, we write the changes up for them and check the work afterwards.
Most sites get the first crawl and priority fixes in the first weeks of a campaign. Large sites with thousands of pages take longer to analyse, and the crawl keeps running afterwards so new issues are caught as the site changes. See [[Enterprise SEO|/organic-seo/enterprise-seo/]] for large sites.
Continuously. Sites change every week: new pages, plugins, products and redesigns all introduce new issues. On every SEO account the Site Crawl in your Client Hub keeps checking for new issues, and the backlink health check refreshes monthly with a full check every quarter.
Yes. AI assistants rely on pages they can crawl, understand and trust, the same foundation Google uses. Clean indexing, fast pages and structured data make your content easier to cite in AI Overviews and ChatGPT answers. See [[AI Search Optimization|/organic-seo/ai-search-optimization/]].
It depends on the size and platform of your site and how much fixing it needs. After a free consultation we send a written proposal with the scope and the price, so you know the cost before any work starts.
