Which tool to start with
The right tool depends on what you have and what you want to know.
- Your site is live and brings in few customers: run the free website audit.
- You are deciding whether to build a site, or what to pay for one: use the website cost calculator.
- You want to know what a site runs on, yours or a competitor's: use the built-with detector.
- Your site is live but does not come up when you search for your business by name: use the check inside the guide to a website not showing up on Google, then work through the reason that matches.
What the free audit checks, and why it is worth running
Enter a website address at the free website audit; there is no login. The audit reads the site and the public web, checks its traffic, rankings and search health, and lists specific fixes in plain words. About 4,000 audits run a month. The reason to check: in Theo's audit of 5,974 small business websites, 48 percent of the 4,027 sites with search data got an estimated zero visitors a month from Google search, as reported in The State of Small Business Websites 2026. The audit shows which side of that line your site is on and what to change.
Where the calculator's numbers come from
The calculator asks for four things: how many pages the site needs, how many years to compare, what an hour of your time is worth, and whether to include the ongoing search work. It then shows, for a DIY builder, a freelancer, an agency and Theo, the upfront cost, the monthly cost, the hours a month each path asks of you, and the total over the years you picked with your time counted. The notes under the table say what each range is based on. Theo's row uses the real plan price: $29.99 a month on Basic for the site and hosting, or $69.99 on Starter with the ongoing search work, free for the first 30 days. Pro, at $129.99, has no row of its own; the pricing page has the full comparison. The guide to how much a small business website costs walks through each path with its sources. The estimate stays on the page; the calculator does not email it, so note the numbers you want to keep.
The two checks that read a site for you
The built-with detector and the check inside the guide to a website not showing up on Google work the same way: paste an address and the check reads the site. The detector reads the homepage and the domain's public DNS: the platform behind the site, who hosts it, who runs its DNS and email, and the analytics, pixels and tools on the page. The Google check looks at the page itself, the file that tells search engines what to skip, and the sitemap, for anything that would keep Google out. Neither asks for a login, and neither replaces the audit, which covers the same ground along with traffic, rankings and fixes.
What to do with the answer
Whichever tool you start with, end on the audit: it turns what you learned into fixes for your own site, and the fixes work on any platform. If there is no site yet, the first build is free; describe the business, look at the preview, and decide on a plan after.
