Hasty SEO · Audit tool
SEO audit tool — 40+ technical checkpoints per URL, prioritised action plan in 24 hours.
A serious SEO audit is not a Lighthouse score and a colour-coded dashboard. Hasty SEO runs a structured crawl across 40+ checkpoints — indexability, schema, Core Web Vitals, hreflang, canonical — and returns a prioritised action plan per URL the engineering and content team can ship from. Free for the first 500 URLs.
- 40+ checkpoints per URL — not a Lighthouse number
- Prioritised action plan per URL — ranked by impact
- Free first audit up to 500 URLs, delivered in 24 hours
Definition
What an SEO audit tool actually does.
It crawls the site like a search engine, parses every response (status code, canonical, hreflang, meta robots, schema, internal links), measures Core Web Vitals per template, and returns a structured list of issues per URL. A serious tool then ranks each issue by impact (lost ranking, lost click, lost crawl budget) and effort (template change vs. one-line fix) so the team knows what to ship first.
How
The four passes inside a real audit.
(1) Crawl — render JS, follow canonical and sitemap, log every response. (2) On-page — title, meta description, headings, internal links, schema, image alt and weight. (3) Technical — robots, sitemap, hreflang, redirects, status codes, broken links, indexability and Core Web Vitals per template. (4) Action plan — group issues by template, rank by impact × effort, attach a one-line fix recommendation per URL or template.
Coverage
What the 40+ checkpoints actually cover.
Crawlability (robots.txt, meta robots, sitemap presence, orphan URLs), indexability (canonical chains, duplicate content, parameter handling), schema (Article, FAQ, BreadcrumbList, Organization, validity), international (hreflang reciprocity, language declarations), performance (LCP, CLS, INP per template — not just one URL), structure (H1 uniqueness, internal link depth, anchor text variety), media (alt text, lazy loading, image weight) and trust (broken links, mixed content, redirect chains).
Recurring
One-off audit, or recurring monitoring.
SEO regressions ship every release. A one-off audit is a snapshot — useful for prioritisation, but stale within a sprint. Recurring monthly (or weekly) audits inside Hasty SEO show whether each shipped fix held, surface new regressions per release, and track Core Web Vitals per template over time so the team catches regressions before ranking drops.

Frequently asked
SEO audit tool — FAQ.
What is an SEO audit tool?+
A tool that crawls a site like a search engine, validates 40+ technical and on-page checkpoints per URL, and returns a prioritised action plan ranked by impact and effort — not a raw dashboard. Useful tools attach a one-line fix recommendation per template so engineering can ship without re-diagnosing each issue.
How does an SEO audit work, step by step?+
Four passes: a JS-rendering crawl that follows canonical and sitemap, an on-page pass for titles, meta, headings, internal links and schema, a technical pass for robots, hreflang, redirects, status codes, indexability and Core Web Vitals per template, and an action-planning pass that groups issues by template and ranks them by impact × effort.
What checkpoints should a serious SEO audit cover?+
Crawlability, indexability, schema validity, international (hreflang reciprocity), performance (LCP / CLS / INP per template, not per URL), structure (H1 uniqueness, internal link depth), media (alt text, lazy loading, image weight), and trust (broken links, mixed content, redirect chains). 40+ checkpoints in total inside Hasty SEO.
What do you get back from an SEO audit?+
A per-URL scorecard, an issue list grouped by template, the top 20 prioritised actions ranked by impact and effort, a Core Web Vitals view per template, a hreflang and canonical map, and a shareable report URL that updates on each recurring run.
How often should you run an SEO audit?+
Start with a one-off audit for prioritisation, then move to a monthly recurring audit. SEO regressions ship every release — only recurring audits catch new regressions per release and verify that each shipped fix held over time.
Can you run an SEO audit yourself without a tool?+
For 10–20 URLs: yes — use Lighthouse, the Search Console URL inspector and a schema validator. Beyond that, manual auditing misses template-level issues (one template breaks 500 URLs the same way), can't track Core Web Vitals per template over time, and can't keep recurring. A tool like Hasty SEO automates the crawl, the parsing and the delta tracking so the senior spends time on the action plan.
