Fix first

Pages with unfinished placeholder text

52 pages

Fix first ranks every issue by the points fixing it would add and the work it takes.

entropyand.co, the site of the company that built Obelisk, audited on October 23, 2026.

See each page the way Google and AI tools see it, before and after its scripts.

Some pages only show their words once scripts load. Obelisk puts both versions side by side and lists what appears late.

Fixed always means checked.

  1. 01

    Fix the issue

    Each issue says what we found, why it matters and how to fix it.

  2. 02

    Press Check now

    We check the pages the issue touched again, without waiting for the next audit.

  3. 03

    See it marked fixed

    It turns fixed only once those pages pass.

  4. 04

    Read what changed

    Every new audit opens with one line on what was fixed and what is new since the last.

Measure your site against three competitors.

We suggest three, and you can pick your own. Their keywords, links and mentions in AI answers sit next to yours, each marked as an estimate with its source and date.

Every plan includes all 129 checks, the free one too.

Plans differ in sites, pages and how often we audit again. Paid plans add PDF and spreadsheet exports. Agency adds branded reports and links your clients open without logging in.

Questions about the SEO audit

What does Site health mean?

The share of checked pages with no real problem. 90 or more is good. Problems only AI search tools have count in the AI search score, and issues you ignore don’t count against it.

How many pages can one audit check?

About 100 on the free audit without an account, 500 on the free plan, 5,000 on Pro and 10,000 on Team and Agency.

Where does the speed data come from?

From real visitors, through Google’s Chrome UX Report, per device. Lab tests fill in what visitor data doesn’t cover.

What if you can’t measure something?

We say so. Not measured is never shown as a zero or a pass.

Can I share the results?

Export the issue list as a CSV on any plan. Paid plans add PDF reports, and Agency sends branded links clients open without logging in.
