Catch the deploy that breaks your SEO.

Hawk Delta checks your Vercel site minutes after every production deploy. When something hurts search, you get the page, the clicks at stake and the fix, while it’s still one commit to revert.

Drag across the timeline. Each pin is a production deploy that Hawk Delta checked.

Minutes, not three weeks.

A deploy that hides a page from Google looks perfect in the browser. Search Console shows the damage weeks later, averaged into a curve. Hawk Delta looks at the deploy itself, right after it goes live.

  1. a41f9c2 goes live

    Vercel promotes the deploy to production. The build passed and every page loads.

  2. Hawk Delta crawls the site

    A minute later, once production really serves the new build: the home page, the pages with the most search clicks, robots.txt and a sample of the sitemap.

  3. Two changes look wrong

    /pricing now says noindex. Twelve blog posts point their canonical at a preview URL.

  4. Checked again, then weighed

    Ninety seconds later the serious ones are fetched again, to rule out a hiccup. /pricing brought 18% of the site’s search clicks in the last 28 days.

  5. You get the email

    Each problem with its pages, the clicks at stake, what Google will likely do and how to fix it. Sent to the people you chose for the site.

  6. The fix ships, the check comes back clean

    The next deploy is checked the same way. Both problems are marked fixed.

13 SEO problems on yoursite.com, found after deploy a41f9c2 (main).

Critical Page is now noindex

Pages
/pricing
At risk
1,690 clicks in the last 28 days, 18% of the site
If it stays
Google drops the page from results the next time it crawls it.
Fix
Remove the noindex from /pricing and redeploy. In Next.js, check metadata.robots in the page or layout.

High: canonical changed on 12 pages (/blog/launch, /blog/vercel-redirects and 10 more).

What a green build can still break.

Every check compares the live site with the last version you accepted, then asks Search Console how much the page is worth.

Before the deploy

<meta name="robots" content="index, follow">

After

<meta name="robots" content="noindex">
What search engines do
Drops the page from results, usually within days. Traffic to it goes to zero and nothing errors.
How Hawk Delta weighs it
Critical. Lowered only for pages with no search impressions, never for the home page.

Also checked on every deploy: redirects and redirect chains, status codes, H1s, meta descriptions, structured data, hreflang, Open Graph, internal links, page weight and security headers.

Monday morning, the week in one email.

Between deploys, Hawk Delta follows the site day by day: clicks, impressions and sessions from Search Console and GA4, with every deploy on the same timeline. Once a week it writes up what changed and the three things worth doing next, on the day and hour you pick, in your client’s time zone.

Every number is computed from your own data. AI writes the sentences, never the figures.

What to do this week

  1. Mark “Book a demo” as a key event in GA4. It fired 61 times and isn’t counted as a conversion.
  2. Rewrite the title of /blog/vercel-redirects. It showed up 9,400 times in Google and got 41 clicks.
  3. Make the www redirect permanent. www.yoursite.com still sends visitors on with a temporary 302.

Only your own data.

Questions.

Do I have to change my code or my build?

No. Hawk Delta reads your public pages after each deploy, the way a crawler does. You connect Vercel once; nothing is installed in the project.

Does it work on the Vercel Hobby plan?

Yes. Deploys reach Hawk Delta through the Vercel integration or GitHub deployment events, which every plan has.

My sites aren’t on Vercel.

Deploy Guard is built for Vercel today. Tell us where you host in the form: it decides what we support next.

Will it flood me with alerts?

No. By default only high and critical problems send an email, and each is fetched a second time first. Pages without search traffic rank lower, and you can change the lowest severity that sends an email.

What will it cost?

Nothing during the beta. Paid plans come after, with prices shown before anyone is charged. Beta testers hear first.

Who is behind it?

Uranoz Solutions, a small studio that builds and maintains sites on Vercel. Hawk Delta started as the tool we use to watch our clients’ sites.
