Page weight
what you see
Every page, and the whole site at once.
Every page ranked by importance, with its issues by severity and how many times each occurs. For each page, load time on broadband, 5G and 4G over the last runs, and page weight split by JavaScript, CSS, images and fonts, first-party against third-party.
Across the site, pages grouped by load time and by weight, heaviest first. A problem in a shared template shows up as hundreds of pages sitting in the same band.
Every managed page, measured the same way.
96 pages load in under 2.5 seconds. 812 take four to five.
From Search Console, clicks, impressions, click-through and position, week over week. Branded, non-brand and undisclosed traffic are kept apart. Pages are grouped by ranking band, with the movement between bands. Each day sits against its 28-day trend and against last year, so you can tell the season from something you did. That last view is marked experimental.

Missing twitter:image:alt
Current as of Sep 25, 2026
Why this matters
When this page is shared, people who cannot see the preview image may miss information that the image communicates. The impact depends on whether the card title and description already provide the same information. This affects the social preview and is not evidence of a search-ranking problem.
How to fix it
Add <meta name="twitter:image:alt" content="..."> next to the Twitter image metadata. Describe the image's useful meaning or purpose rather than its file name. This does not replace alt text for images displayed on the page itself.

From each vendor’s own documentation, September 2026.
This is not a claim that those products are bad, and it is not feature parity in either direction. Siteimprove does spelling, grammar and manual accessibility review that probeo does not. Ahrefs and Semrush do rank tracking and backlink indexing that probeo deliberately leaves alone.
for SEO managers
Two signals, and their disagreement.
Every page carries its PageRank rank next to what Search Console says it actually does: its trajectory and the queries it shows for.
When those two disagree, that is the most actionable data in the room. A page ranked near the top by PageRank that is barely performing has something suppressing it. A traffic driver with low PageRank is fragile.

why it costs what it does
Nobody has to start it.
Ahrefs, Semrush and Screaming Frog find most of these issues too, a crawl at a time. Each crawl is a snapshot: Ahrefs and Semrush schedule them daily at best, and every page crawled counts against a credit or plan limit.
Site Clarity runs continuously on every page you choose, for $0.35 a page a month. A managed page is any page you want probeo to look at.
It is also the ground the rest stands on. Content Intelligence and Content Optimization are built on it and cannot run without it, so it is never a separate tool to keep in step.
Two days of checks on one page, by where the page sits in PageRank. Each tick is a check.
The pages that carry the site are looked at every hour. Nothing waits longer than two days.

questions
What people ask.
Do you need access to our site?
No. probeo reads the public site the way Google does, through your sitemap and public pages, and identifies itself as probeo. If your bot protection blocks it, letting probeo through is the only setup.
How soon do we see anything?
Results start arriving within hours of the first run.
Does it replace Ahrefs or Semrush?
Not for rank tracking or backlinks, which probeo leaves alone. If you have keyword data, bring it. probeo uses it as evidence for the question a page answers.
How often does it check?
Continuously. Attention is weighted toward what changed and toward the pages that matter most.
