Website Audit Services That Tell You Exactly What to Fix

Rankings slipped, conversions are leaking, and your analytics won’t say why. Guessing is expensive. A proper website audit replaces the guesswork with a clear, ordered list of what’s actually holding the site back. SEO Circular inspects your site the way Google’s crawler, an impatient buyer and a senior developer each would — then tells you which fixes pay off first.

Start with the free scan and see live scores on screen. Want the full picture? Within six hours you get a written report covering every technical, SEO, code, speed and accessibility issue we found — each one rated by severity, with the precise fix and the time it takes. No retainer, no lock-in.

What a Website Audit Actually Covers

A website audit is a structured, end-to-end review of every factor that decides whether your pages rank, load quickly, turn visitors into customers and stay legally compliant. In practice it’s several reviews working together: a technical website audit (can search engines crawl and index your pages?), an on-page SEO audit (do those pages earn the rankings they want?), a code review (is the front end lean, or weighed down by bloat and render-blockers?), a speed and Core Web Vitals pass, a content and usability check (does the page answer the searcher’s intent?), and an accessibility audit against WCAG. Roll the results into one score and you have a clear read on how much growth your current setup is quietly leaving behind.

Most free audit tools dump 40 colour-coded warnings on you and walk away, leaving you to figure out which three actually matter. We work differently. SEO Circular runs the industry-standard tools — Screaming Frog, Ahrefs, Google Search Console, Lighthouse and Sitebulb — then has a senior auditor read the results, strip out the noise and order what remains by business impact. Closely related work we do a lot of: SaaS SEO, white-label SEO, and our SEO cost calculator.

Every Audit, One Agency

Twelve Website Audits We Run — Take One or the Whole Stack

Plenty of agencies audit “SEO” and call it a day. We check the entire engine: rankings, code, speed, platform quirks, accessibility, backlinks and traffic loss. Each card below is a standalone deliverable with its own checklist and its own report.

01

Technical Website Audit

The crawl-and-index layer. We surface whatever is stopping search engines from reaching your pages, long before rankings come into play.

  • Crawlability & robots.txt
  • XML sitemaps & indexation
  • Redirect chains & 4xx/5xx
02

Website SEO Audit

On-page signals, content and search intent — the reasons your pages sit on page three when they have every right to be on page one.

  • Title/meta & heading structure
  • Keyword cannibalisation
  • Internal linking & schema
03

Website Code Audit

A senior engineer reads the real source — not a scanner’s summary. We flag bloat, dead code, render-blockers and shaky practices.

  • HTML/CSS/JS quality
  • Render-blocking & bundle size
  • Framework & plugin hygiene
04

Performance & Core Web Vitals

Speed drives both rankings and conversions. We measure LCP, INP and CLS on your actual pages rather than a generic lab average.

  • LCP < 2.5s · INP < 200ms
  • CLS < 0.1 layout shift
  • Image, font & caching wins
05

Ecommerce Website Audit

Faceted navigation, thin product pages, duplicate SKUs and a leaky checkout — the quiet places where catalogue sites lose revenue.

  • Faceted-nav crawl traps
  • Product & category SEO
  • Checkout & conversion leaks
06

Magento Website Audit

Magento and Adobe Commerce run heavy and grow tangled fast. We review the stack the way the developers who built it actually break it.

  • Full Page Cache & Varnish
  • Extension conflicts & bloat
  • Indexer & DB query health
07

Drupal Website Audit

Sprawling modules, outdated core and Views queries that overload the database. A Drupal-aware audit instead of a one-size-fits-all checklist.

  • Core & module versions
  • View/query performance
  • Security advisories & patches
08

ADA Compliance Audit

WCAG 2.2 AA tested with axe and WAVE plus a hands-on screen-reader pass. It lowers legal risk and tidies your markup for SEO at the same time.

  • Contrast, focus & alt text
  • Keyboard & screen-reader nav
  • ARIA & form labelling
09

Website Traffic-Loss Audit

Traffic dropped sharply. We tie the date to its cause — a core update, a migration, accidental de-indexing or a self-inflicted change.

  • GSC drop & cause analysis
  • Algorithm-update mapping
  • Recovery roadmap, ranked
10

Website Backlink Audit

Toxic links, lost authority and unnatural patterns. We separate the links that lift you from the ones setting up a future penalty.

  • Toxic / spam link flags
  • Lost & broken backlinks
  • Disavow file, done right
11

Content Audit

Every URL gets a verdict: keep, merge, rewrite or remove. Thin pages and competing duplicates drag down the whole domain.

  • Keep / merge / prune calls
  • Decay & refresh priorities
  • Intent & gap mapping
12

Website Health Audit

The complete picture. Every layer above rolled into one health score, a single report and one prioritised list of fixes.

  • Single 0–100 health score
  • All five layers combined
  • One ranked action plan

Technical Website Audit

Technical SEO Auditing, Right Down to the Server Response

A technical website audit is where most rankings are won or lost — long before a single word of content is written. It’s the layer we obsess over, because it’s the one your content team can’t fix on their own.

Crawl Budget & Indexation

We map which URLs Google crawls, indexes, skips or has quietly dropped, then track down the traps burning your crawl budget — infinite faceted nav, parameter sprawl, soft 404s and orphan pages.

Core Web Vitals, Field Data

Lab scores can mislead. We pull your real-user CrUX data for LCP, INP and CLS, break it down by template and device, and point to the single metric dragging your mobile rankings.

Rendering & JavaScript SEO

On a React, Vue or Next build, Googlebot can end up seeing an empty shell. We compare the rendered DOM against the raw HTML and catch any content that never reaches the index.

Structured Data & Schema

Product, FAQ, Article, Breadcrumb, Organization — we validate each schema type, repair the errors Google quietly ignores, and add the markup that earns rich results.

Site Architecture & Internal Links

Click depth, link-equity flow and orphan detection. We show why your strongest pages sit five clicks deep and which internal links would pull them up.

Logs, Redirects & Status Codes

Redirect chains, 302s that should be 301s, 5xx spikes and mixed content — the unglamorous details that leak authority on every single request.

Platform-Specific Audits

Ecommerce, Magento and Drupal — Audited the Way They Actually Break

A generic checklist walks straight past platform-specific landmines. We’ve audited enough of each to know exactly where they’re buried.

Ecommerce Website Audit

Faceted navigation spawning millions of crawlable URLs, duplicate SKUs, thin product copy, out-of-stock pages leaking equity and checkout friction. We review catalogue SEO and the conversion funnel together in one pass.

Shopify WooCommerce BigCommerce Custom

Magento Website Audit

Magento and Adobe Commerce are capable but heavy. We check Full Page Cache and Varnish config, extension conflicts, indexer health, slow EAV queries and the front-end bloat that sinks your Core Web Vitals.

Magento 2 Adobe Commerce Hyvä PWA Studio

Drupal Website Audit

Drupal sites decay quietly: outdated core, abandoned modules, unpatched security advisories and Views queries that pound the database. We audit the module stack and query layer, not just the markup.

Drupal 10 Views Layout Builder Commerce
Traffic Recovery

Website Traffic-Loss Audit

Organic traffic is down 40% and the dashboard won’t say why. We line the drop date up against Google’s algorithm-update timeline, your deploy log and your Search Console history — then separate “the algorithm shifted” from “something broke during the redesign.” You leave with the real cause and a recovery plan ordered by how quickly each fix wins traffic back.

  • Drop-date to root-cause analysis
  • Core / Helpful Content update mapping
  • Migration & redesign regression checks
  • Prioritised recovery roadmap
Compliance

ADA Compliance Website Audit

An accessibility audit isn’t optional any more: thousands of ADA and Section 508 lawsuits over inaccessible websites are filed each year, and a bolt-on overlay widget won’t protect you. We test against WCAG 2.2 AA with axe and WAVE, then do the part automation can’t — a manual keyboard and screen-reader pass through your real user journeys. You get a conformance report and a remediation list, which doubles as an SEO win because accessible markup is cleaner markup.

  • WCAG 2.2 AA conformance report
  • Manual screen-reader & keyboard testing
  • Contrast, focus order & ARIA fixes
  • VPAT-ready documentation

Stop guessing why the numbers keep sliding.

A single audit shows you what’s wrong, what it’s costing you and which fix to make first.

Why This Website Audit Agency

Most “Audits” Are a Tool Export With a Logo on It. Ours Isn’t.

We’ve audited more than 1,200 sites across ecommerce, SaaS, content and regulated industries. We know what the scanners miss because we’ve seen the same mistakes a thousand times over.

A Senior Auditor, Not a PDF Export

The person scoping your audit actually reads the site — the code, the search results, the analytics. No junior running a tool and forwarding the output.

Ranked by Revenue, Not by Colour

We don’t dump 200 red flags on you. You get the 20 that move money, in the order we’d fix them, with the impact made explicit.

Five Audits in One

Technical, SEO, code, performance and accessibility — one engagement, one report, one health score. Not five vendors pointing fingers.

Fixed Price, No “It Depends”

A free snapshot, a flat-fee full audit and a fixed-price fix sprint if you want one. You always know the number before anything starts.

We Can Fix It Too

We’re a development shop, not just analysts. If you want the issues resolved, the same team that found them can ship the fixes and re-test the score.

Re-Test Included

After a fix sprint we re-run the full audit on the updated site at no extra charge. Your “all clear” is verified, never assumed.

Frequently Asked Questions

Website Audit — Answered Straight

What is a website audit?
A website audit is a structured review of every factor shaping how your site performs — technical SEO and crawlability, on-page SEO, page speed and Core Web Vitals, code quality and accessibility. The point is to produce one prioritised list of what's holding the site back and what to tackle first. At SEO Circular it folds a technical audit, an on-page SEO audit, a code review, a performance pass and a WCAG accessibility check into a single website health score.
How much does a website audit cost?
SEO Circular begins with a free instant scan so you can see whether there's a problem worth chasing. If you'd like it handled for you, hire us for the full 200-point audit plus the fix: we review every layer and resolve the critical and high-priority issues for a flat $499, one time. Large or complex sites — big ecommerce, Magento, multi-store or enterprise — get a tailored quote. Everything is fixed-price, with no hourly surprises.
What's the difference between a free website audit checker and hiring an audit agency?
A free website audit checker runs the same scanners we use and returns a score plus around 40 generic warnings, all weighted the same, with no clue which few actually matter. An audit agency adds the missing layer: a senior auditor who reads the output, removes the false positives, reviews the real code, and ranks the genuine issues by business impact — each with a precise fix and an effort estimate.
What's included in a technical website audit?
A technical website audit covers crawlability and robots.txt, indexation and XML sitemaps, redirect chains and status codes, Core Web Vitals (LCP, INP, CLS), JavaScript rendering, structured data, site architecture and internal linking, HTTPS and security headers, plus crawl-budget waste such as faceted-nav traps and orphan pages. It's the layer your content team can't fix on their own.
Do you run ecommerce, Magento and Drupal website audits?
Yes. We run platform-specific audits because each one fails in its own way. Ecommerce audits zero in on faceted-nav crawl traps, duplicate SKUs and checkout leaks. Magento audits cover Full Page Cache, extension conflicts, indexers and EAV query performance. Drupal audits look at core and module versions, security advisories and Views query load. A generic checklist simply walks past these issues.
Can a website audit explain why my traffic dropped?
That's precisely what a traffic-loss audit is for. We align your drop date with Google's algorithm-update timeline, your deploy history and your Search Console data to tell an algorithm hit apart from a self-inflicted issue like a botched migration or accidental de-indexing. You get the root cause and a recovery roadmap ordered by how fast each fix earns traffic back.
Do you provide a website audit checklist PDF?
Yes. We'll email you the same 200-point checklist PDF our auditors follow on every project — 200 checks spanning crawl and indexation, on-page SEO, performance, code health, accessibility and off-page trust. Just tell us where to send it; there's no drawn-out funnel.
Is an ADA compliance website audit really necessary?
If you operate in the US and get any meaningful traffic, yes. Thousands of ADA and Section 508 lawsuits over inaccessible websites are filed every year, and an accessibility overlay widget won't shield you. We test against WCAG 2.2 AA with automated tools plus a manual screen-reader and keyboard pass — and the cleaner markup it produces usually helps your SEO as well.
How long does a website audit take?
The free instant scan appears on screen in seconds. The full website audit arrives within six hours of getting access — the crawl and Lighthouse run automatically, then a senior auditor reviews, prioritises and writes up the findings. Very large or complex sites with millions of URLs can take a little longer, and we'll tell you that up front.
Will you fix the issues, or just list them?
Up to you. SEO Circular is a development agency, not only an analyst shop, so the same team that finds the issues can fix them in a fixed-price sprint — every change senior-reviewed and re-tested against the original score. Or take the report to your own developers; it's written to be actioned either way.
Why hire SEO Circular as your website audit agency?
Because most “audits” are a tool export with a logo dropped on top. We've audited more than 1,200 sites, we read the code by hand, and we give you 20 ranked issues that move revenue instead of 200 red flags that don't. Then we can fix them and prove the score moved. Start with the free snapshot and judge the quality before you pay a cent.
