WHAT'S CHECKED
What a technical SEO audit checks: six categories, one grade
Every check rolls up into an overall A+–F grade, plus a per-category score so you know exactly what's dragging you down.
Performance
Real Google PageSpeed Insights & Lighthouse scores for mobile and desktop — the same engine you'd get from Chrome DevTools.
On-Page SEO
Titles, meta descriptions, headers, keyword consistency, and SERP snippet preview for every page crawled.
Technical
SSL, DNS/email records (SPF/DMARC), broken links, redirects, and crawlability issues.
Social
Open Graph tags, Facebook Pixel, and linked social profiles — checked against your site's actual HTML.
AI Search (GEO)
Schema.org identity markup, llms.txt, and how readable your content is to AI crawlers and LLMs.
Backlinks
A summary of your backlink profile and domain authority signals.
Technical · Failed Check
Missing SPF Record
No SPF DNS record found for your domain — emails sent from it may be marked as spam or rejected outright.
Suggested Fix
Add a TXT record: v=spf1 include:_spf.google.com ~allEvery failed check reads like this — what's wrong, why it matters, and exactly how to fix it. Not just a red X.

- 4
Get a prioritized report
Findings are graded A+ through F, grouped by category, with a fix for each one.
A full-site SEO audit, not a sample
Most audit tools cap you at a handful of pages. Aethriss crawls every internal page it can reach from your homepage, so nothing important — a forgotten landing page, an old blog post with a broken link — slips through because it wasn't in a sample.
