How the Free SEO Audit Works

1

Enter a page address

Your homepage, a service page or a competitor's page. No account or email needed.

2

We check the page

Our server reads the page the way search engines and AI crawlers do, plus your robots.txt, sitemap and llms.txt. Google Lighthouse measures mobile speed and Core Web Vitals at the same time.

An overall score, a grade for each category, the five fixes that matter most and a "how to fix" note for every failed check. Download it as a PDF for your web developer.

What the SEO Audit Checks

The audit runs 80+ checks in 13 categories. Each category is weighted by how much it affects rankings, leads and AI visibility for small and local businesses.

Core SEO & Content

26% of your score

Title tag, meta description, H1, canonical tag, noindex rules, HTTP status, amount of content, heading order, readability and placeholder text.

Speed & Mobile

16% of your score

Google Lighthouse performance, LCP, CLS and INP, server response time, compression, render-blocking scripts, mobile viewport and zoom.

Links, Images & Accessibility

19% of your score

Broken internal links, redirects, link text, image alt text, WebP and AVIF formats, image sizes, lazy loading, form labels and page language.

Security & Crawling

15% of your score

HTTPS and HTTP redirects, HSTS, mixed content, security headers, robots.txt rules for Google and Bing, XML sitemap, redirect chains and URL format.

Structured Data & Social

11% of your score

JSON-LD validity, Organization and LocalBusiness schema, breadcrumbs, sameAs profile links, Open Graph tags and share image.

AI Search & Local SEO

13% of your score

ChatGPT, Perplexity and Claude crawler access, llms.txt, Q&A content, FAQ schema, answer-first intro, phone, address, Google Maps and reviews.

Why the Audit Checks AI Search Visibility

More people now get answers from ChatGPT, Google AI Overviews, Gemini, Copilot and Perplexity instead of clicking through search results. These tools can only recommend your business if their crawlers are allowed to read your pages and your content is easy to quote.

The AI checks look for both: whether robots.txt lets AI search crawlers in, and whether the page opens with a direct answer, uses question-style headings and has FAQ schema. This is the core of answer engine optimization (AEO) and generative engine optimization (GEO).

How to Read Your Score

  • 90–100 (A): Excellent. Keep it that way by re-running the audit after each site update.
  • 80–89 (B): Good. A few fixes will put you ahead of most competitors.
  • 70–79 (C): Fair. Usually several technical or content gaps.
  • 50–69 (D): Needs work. Issues are likely holding back your rankings.
  • Below 50 (F): Serious problems, often with indexing, speed or missing content.
  • Start with "Fix these first." One fix on a page template, such as missing alt text or schema, usually fixes every page built from it.

Want These Issues Fixed for You?

A one-page check can’t see site-wide duplicate content, orphan pages, index coverage, backlinks, competitor gaps or Google Business Profile problems. Those need a full crawl plus Search Console access. Our team has fixed technical SEO, local SEO and AI visibility for Los Angeles and nationwide businesses since 2013. Local SEO plans start at $1,500/month.
