Make pages easier to understand
Clear titles, one H1, and a matching meta description help crawlers and users know what the page is about.
On-page SEO analysis
Score titles, meta, headings, and content on every crawled page.
Crawlox checks the on-page SEO signals search engines actually use: title tags, meta descriptions, H1/H2/H3 structure, content depth, image alt text, HTTPS, canonicals, indexability, and internal links.
Page SEO score
Each URL gets a 0–100 score so teams can sort the inventory by pages that need work first.
Title and meta checks
See missing, short, or oversized titles and meta descriptions against practical length ranges.
Heading structure
Confirm a single H1 and enough H2/H3 headings to match your domain targets.
Content depth
Flag thin pages against the minimum word count you set for the domain.
What is on-page SEO analysis?
On-page SEO analysis reviews the HTML signals that help a page rank.
On-page SEO is everything on the page that search engines can read: title, meta description, headings, copy, images, canonical URL, robots directives, and internal links. Crawlox captures those fields during the crawl and turns them into pass, warn, and fail checks with a score and a recommended next step.
Why it matters
Search engines still need clear, crawlable page signals.
Content teams ship pages without titles, duplicate H1s, or thin copy more often than they think. A recurring on-page audit keeps those issues in a queue instead of waiting for a ranking drop.
Protect target keywords
Crawlox infers a target keyword from H1, URL, and title, then checks whether it appears in the right places.
Fix accessibility and image SEO
Missing alt text is both an accessibility gap and a missed image search signal.
Keep indexable pages healthy
HTTPS, canonicals, viewport, and noindex checks stop indexable URLs from quietly falling out of search.
How it works
From crawled HTML to a scored checklist.
01
Fetch the page
The crawler retrieves the public HTML for each reachable URL on the authorized domain.
02
Extract on-page fields
Crawlox reads title, meta description, headings, word count, images, canonical, robots, and links.
03
Apply domain objectives
Compare each page against your targets for SEO score, word count, H2/H3 counts, and keyword presence.
04
Score and recommend
Each check gets a tone, evidence, and a recommendation the content owner can act on.
Checks included
Fourteen on-page signals in one page view.
The page detail view groups crawl evidence so writers, SEOs, and developers can share the same checklist.
Target keyword
Inferred from H1, URL, and title, then checked in title, H1, URL, and meta description.
Title tag
Presence and 30–60 character length for a descriptive, unique title.
Meta description
Presence and 120–160 character length for a compelling snippet.
Headings
Exactly one H1, plus H2 and H3 counts against domain targets.
Content length
Visible word count compared with the minimum you set for the domain.
URL quality
SEO-friendly path, length, and readability for users and crawlers.
HTTPS
Whether the page is served over HTTPS.
Canonical URL
Presence of a canonical so duplicate variants can be consolidated.

Mobile viewport meta tag for usable rendering on small screens.
Indexability
Detect robots noindex so accidental deindexing is visible.
Image alt text
Count images missing descriptive alt attributes.
Internal links
Inbound and outbound internal links plus external link counts.
HTTP status
Confirm important pages return a successful 2xx response.
Last update signal
Last-Modified header and last-seen crawl timestamp.

FAQ
On-page SEO analysis questions.
Short answers for teams looking for a hosted on-page SEO audit tied to a recurring crawl.
What on-page SEO checks does Crawlox run?
Crawlox reviews target keyword presence, title tag, meta description, headings, content length, URL quality, HTTPS, canonical URL, viewport, indexability, image alt text, internal links, HTTP status, and last-update signals.
How is the SEO score calculated?
Each crawled page receives a 0–100 score from the latest on-page checks. You can set a target score for the domain and sort the inventory toward pages that miss it.
Can I set different targets per domain?
Yes. Domain objectives include target SEO score, minimum content word count, H2/H3 heading targets, and how often the inferred keyword should appear.
Does Crawlox replace Google Search Console?
No. Crawlox crawls your site and scores on-page HTML. Search Console remains the source for impressions, clicks, and index coverage reported by Google.
Can I recrawl one page after a fix?
Yes. Open the page and refresh it to re-fetch that URL and update on-page SEO signals without waiting for the next scheduled crawl.
Who is on-page analysis for?
SEO consultants, in-house content teams, agencies, and founders who need a repeating checklist across every public page they own.
