What the free SEO audit checks
A practical SEO audit that turns website signals into next steps.
Spacebrain reviews the public pages it can reach, highlights repeated problems, and organizes the evidence so you can decide what to fix first.
Crawlability
Status codes, redirects, crawl depth, robots rules, canonicals, and internal links.
Indexing signals
Find pages that may be difficult for search engines to discover, understand, or index.
Titles & descriptions
Spot missing, duplicate, short, and overly long metadata across the pages checked.
Content structure
Review headings, thin pages, image alt text, anchor text, and useful on-page context.
Search context
When available, see measured keyword, traffic, competitor, and backlink context alongside the crawl.
Priority fixes
Focus on issues by severity and affected-page share, with examples to verify before changing anything.
How it works
From URL to an SEO action plan.
The audit is designed to be a useful starting point—not a promise of rankings or a replacement for your first-party data.

Use the report well
Fix patterns, then measure the change.
A crawler sees public symptoms; your team supplies product, editorial, and technical context. That combination creates better SEO decisions.
Verify the examples
Check each example in the rendered page, source, CMS, or deployment before treating it as a problem.
Repair shared causes
Prioritize templates, shared navigation, canonicals, and repeated content patterns before making one-off edits.
Measure in first-party tools
Use Search Console and Bing Webmaster Tools to validate indexing, impressions, clicks, and changes over time.
Transparent methodology
What this SEO checker can tell you.
The audit makes read-only requests to publicly accessible HTML pages. It does not edit your website, submit forms, or deploy changes.
It may not see authenticated, blocked, JavaScript-rendered, international, disconnected, or out-of-limit pages. A report can be partial when pages time out or refuse automated requests.
Search and backlink context is shown only when measured provider data is available. It is not a substitute for Search Console, analytics, or a Google ranking signal.
After your free SEO audit
Turn the findings into a practical 30-day SEO plan.
Use the report to make a short, evidence-led sequence of changes rather than chasing a score in isolation.
Validate the highest-impact findings
Confirm example URLs, group repeated issues by template, and assign a clear owner before editing.
Fix the foundations
Address crawl and indexing blockers first, then improve metadata, headings, links, images, and thin content in reviewable batches.
Recrawl and compare
Check the new release, confirm repeated issues are resolved, and compare with first-party search data.
Frequently asked questions
Frequently asked questions
Straight answers about the audit, the report, and how to use the results.
Is the SEO audit really free?
Yes. You can start a free audit of a public website without a credit card or paid Spacebrain plan.
Do I need a Spacebrain account?
No. Start a read-only audit without an account. Create one only when you want to keep working in the free SEO workspace.
How many pages does the audit check?
The free audit checks up to 50 publicly accessible HTML pages through a bounded crawl and reports the pages checked.
Will the crawler change my website?
No. It makes read-only requests to public pages and does not edit content, submit forms, or deploy changes.
Why might a report be partial?
Pages can time out, block automated requests, return errors, rely on client-side rendering, or fall outside the crawl limit.
Is the SEO health score a Google ranking factor?
No. It is a Spacebrain summary of observed crawl and content signals, not a Google metric, ranking promise, or traffic guarantee.
