What the site audit checks
The crawler inspects every page across the dimensions that actually move rankings, then groups what it finds by severity so you fix the highest-impact issues first.
Indexability
Robots rules, noindex tags, canonicals and sitemap coverage, so Google can actually find and index the pages you care about.
Crawlability & status codes
Every 2xx, 3xx and 4xx, plus redirect chains and loops that quietly leak link equity and crawl budget.
On-page SEO
Missing or duplicate titles and meta descriptions, heading structure and other on-page signals across every page.
Internal links & structure
Orphan pages, click depth and internal link opportunities, so your most important pages get the authority they need.
Performance & Core Web Vitals
Per-page speed and Core Web Vitals snapshots to find the pages dragging down rankings and conversions.
Images
Missing alt text and oversized images that hurt accessibility, image search and load time.
JavaScript & CSS
Render-blocking and heavy resources, flagged so developers know exactly what to trim.
Social tags & hreflang
Open Graph and Twitter cards for clean sharing, plus hreflang checks for multi-language sites.

Site audit FAQ
Is the site audit really free?
Yes, completely. You can audit any single page for free with no signup using the tool above, and full-site crawls are free on every plan, including the free plan. There is nothing to meter, so you can crawl as often as you like.
How many pages can the site audit crawl?
Your whole site. There is no per-page charge for crawling, so you can audit every page on your domain. Larger sites simply take a little longer to process while every page is checked.
What does the site audit actually check?
It runs 300-plus technical and on-page checks across indexability, crawlability and status codes, internal links and structure, performance and Core Web Vitals, content and duplicates, images, JavaScript and CSS, social tags and hreflang. Every issue is grouped by severity and mapped to the pages it affects.
Can I export the audit as a report?
Yes. Every audit exports to a branded PDF you can send to clients or your development team, plus bulk CSV export for the raw data.
How is this different from Google PageSpeed Insights?
PageSpeed Insights scores the performance of one page. OneClickSEO crawls your whole site and checks technical SEO across many dimensions, tracks a health score over time, compares crawls, and alerts you to new issues, all in one place.
How often should I run a site audit?
Run one after any major change to your site, and on a recurring schedule otherwise. Alerts and crawl history mean you catch new technical issues as they appear instead of discovering them after rankings drop.
