Core Web Vitals
Largest Contentful Paint, Interaction to Next Paint and layout shift, taken from real Chrome users where Google has the data, not a guess from a lab run. These are confirmed ranking factors.

We crawl your pages, pull your real Core Web Vitals from Google, and check the security, local-search and email-authentication faults that quietly cost you customers, then tell you exactly how to fix each one.
We scan the public homepage and your DNS records. Nothing is installed and no login is needed. Reports are reachable by link only and are not offered to search engines unless the domain owner asks us to publish them.
Largest Contentful Paint, Interaction to Next Paint and layout shift, taken from real Chrome users where Google has the data, not a guess from a lab run. These are confirmed ranking factors.
Whether Google can read your business name, address, phone, opening hours and geo coordinates. Map results are assembled from structured data, not from what a person sees on the page.
HTTPS, certificate expiry and trust chain, TLS version, mixed content, cookie flags and the full security-header suite. An expired certificate takes a site down as effectively as a server failure.
SPF, DKIM, DMARC, MTA-STS and blocklist status. Almost no audit tool checks this, and it is what we find broken most often: usually a domain publishing two SPF records where exactly one is allowed, which makes authentication fail outright.
Duplicate titles, missing descriptions, thin pages, accidental noindex tags, broken internal links and redirect chains, found by crawling up to a dozen pages, not by looking at your homepage alone.
Nameserver redundancy, DNSSEC, CAA records, caching and compression configuration, and whether your server's IP sits on a mail blocklist.
Every report gets a permanent link.
Yes. Enter a website address and you get the full report, with every issue we found and how to fix it. No account, no card, no trial.
Thirty to ninety seconds. We crawl up to a dozen of your pages, query your DNS and certificate directly, and ask Google for your Core Web Vitals, so it takes longer than a single-page checker — and finds a great deal more.
Not unless you ask. Reports are reachable by their link but carry a noindex directive and are kept out of our sitemap. If you own the domain you can prove it with a DNS record and then choose to publish the report — or delete it, along with the scan history, permanently.
We keep the report so the link keeps working and so you can compare it against a later scan. We do not sell data, and we never contact anyone who has not asked us to.
Yes. Every report ends with the option to have us do the work. There is no obligation, and the report is complete and useful whether or not you take it up.
Because they are the most commonly broken thing we see and almost no audit tool looks at them. BounceZero's main business is email deliverability, so we check SPF, DKIM and DMARC as part of every scan.
We crawl a sample of your pages rather than all of them, and Core Web Vitals come from Google's field data, which only exists once a site has enough Chrome traffic. Where we cannot measure something we mark it skipped and leave it out of your score, rather than estimating it.
Ninety seconds from now you'll know.
Free, no account, and the report link is permanent.
