It is searched about **13.6M** times a month on Google, worldwide (Google Ads, Sept 2026), at about $0.03 a click in search ads: a month of its searches would cost about **$408K** as search ads.

A top search keyword is one of the searches that bring a site the most visitors, by estimate. It is not a position in Google, and the order here is not a ranking. Visits (est.): the traffic estimate's own figure for the keyword on that site, which behaves like visits a month, not an amount of money (2026-09-29: it had been shown in dollars). Ad value is what advertisers pay for the keyword — its searches × cost per click — not how hard it is to rank for. This page is kept out of search results until 15 sites share the keyword. Searches, cost per click and ad value above: Google Ads, worldwide. Sites and their visits: third-party traffic estimates, Sept 2026. The traffic estimates' own searches figure for the keyword is in the section below; the two sources often differ several times over. --- Source: mxverify, "1 Site Where periodic table Is a Top Search Keyword", https://mxverify.uk/keywords/periodic-table (retrieved 2026-11-01).
