Change detection

Know what changed on your sites, the day after it happened

When traffic drops, the first question is “what changed?”. Helicopterview keeps a daily fingerprint of every site, so the answer is already waiting for you.

No credit card. Nothing to install.

What we check

Everything change detection covers

Tracking tags

An alert when Google Analytics, Tag Manager, Google Ads or Meta pixels disappear from a site.

Plugins and software

WordPress plugins added or removed, and software version changes.

Titles and headings

Changes to the homepage title, meta description, main heading and canonical URL.

Indexing

A noindex tag or a blocking robots.txt that suddenly appears.

Hosting and DNS

A new server IP, different nameservers or changed mail servers.

Redirects

The homepage suddenly resolving to a different URL.

Why it matters

Small problems, big consequences

Most website problems start with a change somebody made: a theme update that dropped the analytics tag, a developer who left noindex on, a DNS move that broke email. Seeing the change the next day turns a mystery into a five-minute fix.

  • Part of one daily scan that also covers availability, security, speed, search, email and tracking.
  • Findings are ranked by impact across all your sites, so you always know what to do first.
  • Every finding explains why it matters and exactly how to fix it.

Frequently asked questions

How often do you compare?

Every daily full scan is compared with the previous one.

Will I be flooded with small changes?

No. Only significant changes, like a removed tag or a server move, go on the fix list. Smaller ones appear in the site’s change history.

Do you watch the content of my pages?

We watch the technical fingerprint (tags, titles, plugins, DNS), not your text or images.

Can I see the history?

Yes. Every site has a timeline of recent changes.
