Sample analysis: how BuiltWith and Hudu earn their visitors

This is a real competitor analysis, run for SlopDox, a new tool we own that records what a website runs on. We took apart two established names near it: BuiltWith and Hudu. Every number is an estimate from public search data for Google in the United States, taken on November 13, 2026.

SEO: what Google sends them

• BuiltWith is big because it has a page for every website. It appears for about 12,211 searches. Most of its visits come from people searching another site’s name and landing on BuiltWith’s page about it, so the headline visitor estimate flatters it and we leave it out.
• Its homepage wins the plain question. It is first for “what website is this” (about 8,100 searches a month) and earns about 3,341 visits a month from searches like it.
• Hudu is small in search and mostly its own name. About 1,815 visits a month across 310 searches, and 88% of the traffic from its top 100 searches is people typing “hudu”.

The pages doing the work

• BuiltWith’s trend pages earn its links. Of its 42 strongest linking sites, 21 point at its technology trend pages, not the homepage. About 25,283 sites link to it, down 1,250 in 11 months.
• Hudu’s guides and comparison pages earn the rest. A guide ranks fourth for “best documentation practices”, and its page comparing itself with a rival ranks second for that rival’s “alternative” search.
• Hudu is growing its links fast. About 650 sites link to it, up 325 in 11 months.

AEO: where Google’s AI Overview cites them

• BuiltWith is shown as a source in the AI Overview for about 498 searches.
• Hudu is shown as a source for about 66.

GEO: AI assistants

This sample did not ask ChatGPT, Gemini, Claude or Perplexity who they recommend. Those checks are coming soon, and we say so rather than guess. See SEO, AEO and GEO explained.

What a new tool can copy

• Own one plain question on the homepage, worded the way people ask it.
• Publish something others want to link to, such as figures nobody else has.
• Write an honest comparison page for each better-known rival.

What this is, honestly

• Visitor and search numbers are estimates, not counts from the sites themselves.
• We read public pages and public search data only. A few pages could not be read and were left out.
• It shows what these sites do. It is not a promise of where anyone will appear.
• We are not connected to BuiltWith or Hudu.
