Free SEO & AEO Tools
Eleven tools we built for our own client work and made public. Every one runs against your live site, gives you the real answer, and asks for nothing in return — no signup, no email gate, no page limits.
Most free SEO tools exist to collect an email address. You run the check, you get a score, and then you get a form. We took the opposite approach: full results, immediately, because the tools are only useful as marketing if they are genuinely useful as tools.
Everything here measures rather than estimates. We fetch your pages, parse your HTML, read your robots.txt and sitemap, and report what is actually there. Where a number is an estimate — keyword difficulty, for instance — we say so plainly instead of dressing it up.
If you want the problems fixed rather than just found, that is what we do for a living. But the diagnosis is free either way.

Built by a Sarasota SEO agency, not a software company
These tools exist because we kept building them for ourselves. RevSurge Digital runs
technical SEO and answer engine optimization for businesses
around Sarasota and Bradenton, and every check on this page started as a script one of us wrote
to stop making the same mistake twice on a client site.
That shows up in what they measure. A tool built by a software company optimises for
a number that demos well. These optimise for the things that actually moved rankings for a
home services company in Sarasota or a
restaurant on the Gulf Coast — crawlability of
service-area pages, whether a machine can tell where you operate, whether the pages that earn
local business are the pages search engines can actually read.
They work identically for a site anywhere in the world, and plenty of people outside
Florida use them. But if you are a local business here and you would rather have the problems
fixed than listed, we are ten minutes from most of Sarasota County —
1343 Main Street, Sarasota, FL 34236.
Frequently asked questions
Are these tools really free?
Yes. No signup, no email required to see results, no usage limits. We built them for our own client work and publishing them costs us very little. If you want the fixes implemented, that is the paid part.
Do you store my data?
We do not store the URLs you check or the results you get. If you choose to have a report emailed to you, we store that email address so we can send it and follow up — which you can opt out of at any time.
How accurate are the results?
Everything we report as measured is measured directly from your live site — HTML, headers, robots.txt, sitemap and schema. Anything estimated is labeled as an estimate. We would rather give you a smaller number of numbers you can trust.
Can I use these on client sites?
Yes, on any site you like. Agencies and consultants are welcome to use them in client work. A link back is appreciated but not required.
Which tool should I start with?
The GEO Audit. It covers the widest ground and its priority list will usually point you at the two or three specific tools you need next.
Prefer we just do it?
Every tool on this page finds problems. Fixing them across a whole site — and keeping them fixed as the site changes — is the work. That is what RevSurge Digital does for clients across Sarasota, Bradenton and Florida.
