what a free kalenux seo audit covers

Not a one-page checker. The whole site, by severity.

Issues grouped so you fix the root cause once.

what the instant check does, versus the full crawl

One page now, or the whole site compared.

A single request is cheap enough to run instantly. A whole-site crawl needs a verified domain and somewhere to store the result.

what is in a free seo audit report?

A useful report says what’s wrong, where, and what to change.

A weak one shows a score and asks for your email.

⧉Grouped by cause, not by pageEight hundred missing descriptions is usually one template. A report should collapse counts into causes.
⌖URL, expected, foundEvery finding names the page, what was expected and what was found: ranked by impact.
◎A score is a prompt, not a verdictScores are weighted sums; useful for one site over time, near-meaningless across tools.
↗History is the evidenceTwo runs and the difference between them are the only honest proof your work changed anything.
ASK BEFORE COMMITTINGDoes it crawl the whole site?Or only a sample that hides template faults.
ASK BEFORE COMMITTINGDoes it keep history?So you can prove a fix worked.
ASK BEFORE COMMITTINGDoes it export?So findings reach whoever makes the change.
frequently asked questions

Straight answers about the free audit.

Q1What does the instant free check look at?

It fetches the one page you paste and runs a set of on-page checks against it: HTTPS, whether the page parses, title tag length, meta description length, whether the page is indexable, a single H1, a canonical tag, a mobile viewport tag, Open Graph tags, the html lang attribute, and mixed-content assets on an HTTPS page. It does not crawl any other pages.

Q2How is the instant check different from the full free audit?

The instant check needs no account and looks at a single page in seconds. The full audit needs a free account, verifies you own the domain, then crawls your whole site up to 500 pages against 240+ checks plus PageSpeed and Core Web Vitals, and your first one is free.

Q3Do I need to verify my site?

Yes, for the full-site crawl. Verification is a DNS record, a meta tag, or a file upload, and it exists so the tool only ever crawls sites you actually control. The instant single-page check needs no verification because it only reads one public page.

Q4Is the free audit a full crawl or a sample?

It is the same crawl a paid credit buys: up to 500 pages on your first free run, with issues grouped by severity and category rather than a handful of sampled pages.

Q5What happens after my free audit?

Nothing is charged automatically. When you want to run another audit, you buy a one-time credit pack starting at $9, and unused credits never expire. There is no subscription and no card kept on file.

in depth · 4 primary sources

What a free check can and can’t tell you.

The sources behind what the free check tests.

01One page, the basics

A single-page check confirms Google’s technical requirements for that URL: not blocked, HTTP 200, indexable content [1].

It shows what the page serves now. Search Console’s Page indexing report shows what Google last saw [2].

02Pair it with Google’s free data

PageSpeed Insights adds real-user speed data [3], and the Performance report shows the clicks and impressions the page actually earns [4].

KEY FACTAn instant check is a snapshot. Site-wide issues such as orphan pages need a full crawl.
