What Similarweb does in ChatGPT
The Similarweb plugin brings Similarweb's market data into ChatGPT. You can research any website or app by asking a question, such as how a site's traffic has moved over six months, and get the figures back in the chat instead of building a report in a separate tool.
It covers traffic sources, acquisition channels, referring sites, search keywords and audience details such as geography and demographics. You can put one site next to its competitors, or compare performance against others in the same industry, and ask ChatGPT to summarize where a site could grow.
The listing aims it at marketers, analysts, investors and strategists. It works best when you name the domains you care about and the time period you want, so the answer stays focused on the numbers you need. You can then ask follow-up questions in the same chat to dig deeper.
