Do your e-mails arrive? Topics such as SPF, DKIM, DMARC, MX, STARTTLS, PTR, MTA-STS, TLS-RPT, DNSSEC, blocklists, bulk sender rules and BIMI. When needed, test mails show whether your e-mails are delivered at different mail providers.
Made for agencies, website owners and companies
One report. Everything in view.
With bytereport you check your website or domain for performance, SEO, accessibility, AI visibility, e-mail delivery, security and consent management. With an account you also get reports regularly and so keep everything in view for good.
One report format for every topic
A bytereport checks several categories and always delivers the results in the same format: a score per category, findings by urgency, a fix to copy. With an account all checks come together in one combined report, updated regularly if you like.
Is your web server configured properly? HTTPS and transport, protection against injection, isolation and privacy, cookies and whatever else your server gives away. One request, ready header lines as the fix.
Does your website load fast enough? Is there room for technical improvement? How well do your server and the network perform, how do you score on Google's Core Web Vitals?
We check how search engines can crawl the site, whether content and meta data are reachable and how well structured the information is. The way a search engine crawler sees the page.
Can AI crawlers read your website well? With an account you also send your prompts to ChatGPT, Claude, Gemini and others, and we check whether you appear in Google's AI Overviews.
We check a web page for a sound structure of headings, text alternatives, link texts and ARIA markup. With an account we also check contrast, focus and click targets in a real browser, over several of your pages if you like.
Consent check
Pro and TeamDoes your website set cookies or load third parties before anyone agrees? We load your pages in a real browser without a click, after “Reject” and after “Accept all”, and compare the result with your privacy policy.
