How it works

From address to action plan in three steps.

  1. Enter your website

    Any public page. Your home page is a good start; key service or product pages work too.

  2. We check 100+ signals

    We read the page like a crawler, test robots.txt, sitemap, SSL and DNS, run Google’s speed test, and let AI estimate keywords and priorities.

  3. Share your report

    Get a 14-page report with scores, plain-English explanations and a ranked fix list. Send it to your team or client with one tap.

Nine areas, one score

Each area gets its own page in the report with what passed, what failed and how to fix it.

Can ChatGPT read your website?

Many sites block AI assistants by accident through a plugin, firewall or copied robots.txt. If they can’t read you, they can’t recommend you.

Frequently asked questions

Is Duealerts really free?

Yes. Audits and all free tools cost nothing, need no sign-up or card, and have no daily limit. We earn money only when a business asks us to fix or improve their site.

What does “find what’s due in your site” mean?

Every website has work that is overdue: a blocked AI crawler, a missing description, a slow hero image, an expiring certificate. Duealerts finds those items, ranks them by impact and tells you how to clear each one.

What is the difference between SEO, AEO and GEO?

SEO helps your pages rank in Google and Bing. AEO helps your content become the direct answer in featured snippets and voice assistants. GEO helps AI assistants such as ChatGPT, Perplexity, Gemini and Copilot understand, trust and cite your site.

How long does an audit take?

Usually one to two minutes. Most of that time is Google’s speed test loading your page on a simulated phone and desktop.

Can I share the report with a client or my team?

Yes. Every report has its own private link. Use the Share button to send it by message, email or any app on your phone.

Where do keyword and backlink figures come from?

On-page, technical, speed, security and AI crawler results are measured directly. Keyword volumes, ranking positions and backlink strength are AI estimates and are labelled as estimates in the report.

Does the audit change anything on my website?

No. It only reads public pages, the same way a search engine does.

Can you fix the issues for me?

Yes. Our team can fix technical issues, improve rankings and build AI visibility. Send a request from any report or the services page and we reply within one business day.
