SEO Audit Tool: Run a Website SEO Audit, Technical SEO Audit, and SEO Audit Report on Autopilot
An SEO audit tool crawls your website, checks each page against the technical and on-page rules search engines use, and hands you a prioritized list of what is broken and what it is costing you. Rankable runs 66 automated checks per page, covering indexability, canonicals, titles, meta descriptions, heading structure, content depth, images, speed, schema, and internal links, then scores every page and tracks the score over time. The difference from a standard crawler is what happens next: Rankable does not stop at the report. It researches the keywords the audit shows you are missing, writes the pages, and publishes them.
Built for US agencies, ecommerce teams, and B2B marketers who need the audit and the fix in one place, not a 400-row spreadsheet nobody actions.

What an SEO audit tool actually does, and where most of them stop
Every SEO audit tool does roughly the same first job. It fetches your pages the way a crawler would, parses the HTML, and compares what it finds against a catalog of rules: is this page indexable, does it have exactly one H1, is the title inside the length search engines display, does the canonical point somewhere sane, are the images missing alt text, how long does the server take to respond. Rankable runs 66 of those checks on every page and scores each one from 0 to 100, then rolls them up into a site score you can watch move.
That part is commodity. Ahrefs, Semrush, Screaming Frog, and Sitebulb all crawl well, and the biggest of them crawl deeper than we do. Where the standard workflow breaks is after the report lands. A 200-page site produces a few hundred flagged rows. Somebody has to read them, decide which ones actually affect rankings, write the tickets, and then find someone to do the work. In most US marketing teams that person does not exist, so the audit gets exported to a spreadsheet, shared in Slack, and quietly forgotten. The site scores exactly the same six months later.
The second failure is more expensive and almost no audit tool addresses it. Roughly half of what an audit surfaces is not a broken tag at all. It is thin content, missing pages, no internal links pointing at the money page, and no article answering the questions your buyers type before they buy. Those are not fixes, they are writing assignments. Rankable is built around that gap: the audit tells you what is missing, and the same system researches the keywords, writes the article, links it into your site, and publishes it on the schedule you set.
SEO audit tools compared: 2026 US pricing and what each one is actually best at
Published list pricing as of July 2026. These tools are not interchangeable, and for deep technical crawls of very large sites the dedicated crawlers still win. Read this as a map of which job each tool is best at, not a claim that one replaces all the others.
| Tool | 2026 US price | What it audits best | Best for |
|---|---|---|---|
| Rankable | Subscription, 14-day free trial | 66 on-page and technical checks per page, plus the content gaps the audit exposes | Teams that want the audit findings turned into published pages, not a backlog |
| Ahrefs Site Audit | $129 to $499/mo (Lite to Advanced) | Technical crawl paired with the largest backlink index in the category | Backlink-heavy audits and competitive research |
| Semrush Site Audit | $139.95 to $499.95/mo (Pro to Business) | Broad crawl inside an all-in-one marketing suite | Marketing teams that want research, tracking, and audits in one login |
| Screaming Frog | Free up to 500 URLs, or about $199/yr | Raw crawl depth, redirect chains, log-style technical detail | Technical SEOs who want maximum crawl control at the lowest price |
| Sitebulb | From about $13.50/mo desktop, $34/mo cloud | Audit visualization and client-ready explanations of issues | Consultants presenting findings to non-technical stakeholders |
| Google Search Console | No cost | How Google itself sees indexing, coverage, and Core Web Vitals | Ground truth on indexing, but it will not crawl your site on demand |

What Rankable checks on every page
The 66 checks group into six categories. Each one returns a score, a pass, warning, or fail status, and the specific evidence, so you are not guessing which element triggered the flag.
Indexability and canonicals
Meta robots noindex, X-Robots-Tag headers, missing canonicals, conflicting canonicals, and 4xx or 5xx status codes. These are the checks worth reading first, because a page that cannot be indexed cannot rank no matter how good it is.
Titles, meta descriptions, and headings
Missing, too long, or too short titles and meta descriptions, missing H1, multiple H1s, and broken heading hierarchy where an H3 appears with no H2 above it. This is where the fastest ranking gains usually sit on sites that already have traffic.
Content depth and readability
Word count against a thin-content threshold, low-content pages, and a Flesch reading ease score. Thin pages are the single most common finding on ecommerce and local sites, and the one that needs writing rather than a tag fix.
Images and media
Missing alt text, alt text that runs too long, broken image references, images served without width and height, no lazy loading, no modern formats, and unhelpful filenames. Image issues rarely sink a page on their own but they compound with speed.
Speed and server response
Time to first byte against a 600ms target, HTML page weight, total resource requests, render-blocking CSS and JavaScript in the head, unminified and uncompressed assets, oversized JavaScript, and cache headers.
Links, schema, and social markup
Broken external links, links pointing at redirects, external links missing rel attributes, Article schema, breadcrumbs, pagination markup, Open Graph and Twitter card completeness, and Open Graph images.
How to run an SEO audit that actually changes something
Four steps. The first two are what every audit tool does. The last two are where sites either improve or stay exactly where they were.
Crawl and score every page
Add your domain. Rankable fetches your pages, runs all 66 checks against each one, and produces a per-page score plus a site-level score. Homepage first, then the rest of your indexed pages. You get the evidence behind each flag, not just a red dot.
Sort by what actually moves rankings
A 400-row audit is not a to-do list, it is a haystack. Fix indexability and status codes first, then titles and H1s on pages that already get impressions, then speed, then image hygiene. A missing alt tag on a page nobody can index is not worth an hour of anyone's time.
Separate the tag fixes from the writing assignments
Thin content, missing pages, and no internal links are not developer tickets. They need someone to research the keyword, write the page, and link it in. This is the half of every audit that stalls, and it is the half that carries most of the traffic upside.
Fix, publish, and re-audit on a schedule
Rankable writes and publishes the missing content, then re-audits so you can see the score move rather than trusting that the work landed. Set the cadence and the loop runs without anyone remembering to run it.
Who runs these audits and what they are looking for
Agencies auditing a roster of clients
The audit is usually how the relationship starts, and the finding that closes the deal is almost always content, not tags. Running the same 66 checks across every client site gives you a consistent scorecard for pitches and quarterly reviews without a technical SEO manually crawling each account.
Ecommerce teams with thousands of pages
Category and product pages are where thin content, duplicate titles, and canonical conflicts live at scale. Large stores benefit from quarterly audits rather than annual ones, because catalog changes break things faster than anyone notices.
B2B and SaaS marketing teams
Fast-moving sites accumulate orphaned pages, stale canonicals from a site migration, and product pages with no supporting content. Audits catch the technical drift; the missing article for each buying-stage question is what actually costs pipeline.
Small businesses with a site somebody built once
Sites built years ago and left alone tend to fail the same handful of checks: no meta descriptions, one H1 missing on the money page, images with no alt text, a slow host. Those are cheap fixes with real upside, and you should know about them before paying anyone a retainer.
Rankable vs a dedicated site crawler
An honest comparison, including where the crawlers win. If your job today is a deep technical crawl of a 500,000-URL site with JavaScript rendering and log file analysis, use Screaming Frog or Ahrefs. Rankable is the better choice when the audit is a means to an end and the end is published pages.
| What you are comparing | Rankable | Dedicated site crawler |
|---|---|---|
| Checks per page | 66 technical and on-page checks with scores and evidence | Often 100+ checks, deeper technical coverage |
| Crawl depth on very large sites | Built for the pages that matter, not half a million URLs | Wins clearly, this is what they are engineered for |
| Log files and JavaScript rendering | Not covered | Available on the higher tiers |
| Content gap findings | Thin content and missing pages flagged as writing assignments | Flagged as a row in a report |
| Who does the fixing | Rankable researches, writes, links, and publishes the missing content | You, your team, or a freelance writer |
| Re-audit cadence | Scheduled, with score history you can show a client | Scheduled crawls on most paid plans |
| Typical 2026 US price | Subscription with a 14-day free trial | $129 to $500 a month, or about $199 a year for desktop crawlers |
SEO audit questions people actually ask
What is an SEO audit?
An SEO audit is a structured review of a website against the technical, on-page, and content rules search engines use to crawl, index, and rank pages. It checks whether pages can be indexed, whether titles, headings, and metadata are correct, how fast pages load, and where content or internal links are missing. The output is a prioritized list of fixes.
How much does an SEO audit cost?
Most US companies pay between $500 and $15,000 for a one-time professional SEO audit in 2026, and a standard audit of a roughly 200-page site usually lands between $2,000 and $6,000. Ahrefs' survey of 439 SEO providers found the most common per-project fee is $2,501 to $5,000. Software-based audits cost a fraction of that.
How often should you do an SEO audit?
Most websites do well with a full SEO audit every 6 to 12 months. Large ecommerce catalogs and fast-moving SaaS sites benefit from quarterly audits, because product changes, migrations, and template edits break canonicals and titles faster than anyone notices. Continuous automated checks catch regressions between the scheduled reviews.
What does an SEO audit include?
A complete SEO audit covers five areas: technical health (indexability, status codes, canonicals, speed), on-page elements (titles, meta descriptions, headings, images), content quality and depth, the internal and external link profile, and structured data. Rankable's audit runs 66 automated checks across those areas on every page it crawls.
How do I do an SEO audit of a website?
Crawl every indexable page, check that each one returns a 200 status and is not blocked by robots directives, confirm each has one H1 and a unique title and meta description in the right length range, measure server response and page weight, then find pages that are thin or missing entirely. Fix indexability first, then on-page, then speed.
What is a technical SEO audit?
A technical SEO audit is the subset that looks at how search engines access a site rather than what it says: status codes, robots directives, canonical tags, redirect chains, server response time, render-blocking resources, structured data, and mobile viewport setup. It answers whether your pages can be crawled, indexed, and rendered correctly.
Do SEO audit tools actually improve rankings?
Not on their own. An audit is a diagnostic, and diagnostics do not change anything until someone acts on them. The findings that move rankings most reliably are indexability failures on important pages, missing or duplicate titles on pages that already get impressions, and thin or absent content on commercial queries.
Is an SEO audit tool better than hiring an agency?
They solve different halves of the problem. An agency brings judgment, technical execution, and accountability, and charges $2,000 to $6,000 for a thorough one-time audit. A tool runs the same checks continuously for a fraction of that but cannot decide what matters for your business. Most teams get the best result running both.
