Free SEO & Web Tools Online: DNS, SMTP, Metadata & More

Website work comes with a constant stream of diagnostic questions that do not need enterprise software to answer but do require the right tool. Is that DNS change live yet? What title tag and meta description is a page showing to Google? Is the mail server actually responding? How long is that redirect chain? Web developers, SEO professionals, and site owners run these checks regularly, and waiting on a developer or paying for an agency platform every time gets old fast.

The free SEO and web tools on FileReadyNow give you browser access to the checks that come up most. The DNS lookup tool pulls live records including A, CNAME, MX, and TXT entries without needing the command line or a paid API. The metadata viewer fetches any URL and displays its title tag, meta description, canonical, Open Graph tags, and structured data in a clean readable format. The SMTP tester checks whether a mail server is responding on the standard ports, which is useful for tracking down email delivery issues before escalating to a hosting provider.

Other tools in this section cover redirect chains, HTTP response headers, sitemap structure, and robots.txt files. Together they make up the quick-reference toolkit that technical SEO professionals and developers rely on during audits and site migrations.

Every tool pulls live data so results reflect the current state of the web, not a cached snapshot from last week. No account required. Whether you are debugging a configuration, checking your own site health, or running a quick audit for a client, these tools give you what you need in a few seconds.
