A new study from Mencoro tracked 176,332 AI citations for 42 large consumer brands in Spain and found that each AI engine leans on different sources. Google’s AI leaned on Instagram, ChatGPT on newspapers and official records, and Perplexity on YouTube. Local service businesses are a different world, so Diib checked what AI assistants cite when people ask about cleaning services.<\/p>\n\n\n\n
Diib’s AI visibility scans ask AI assistants the kinds of questions a customer might ask about a business’s services, then record which websites the answers cite. This covers scans of cleaning company websites between September 14 and October 2, 2026.<\/p>\n\n\n\n This is aggregated Diib data. Diib’s scans don’t include Google’s AI Overviews (the AI summaries at the top of Google results), so this can’t test the Instagram finding directly. The Claude and Perplexity samples are smaller than ChatGPT’s. The overall picture lines up with Mencoro’s broader result that most AI citations go to company websites, not media or social platforms.<\/p>\n","protected":false},"excerpt":{"rendered":" In Diib’s AI visibility scans of 705 cleaning company websites, about 7 in 10 sources ChatGPT cited were other businesses’ websites, mostly other cleaning companies.
