Social-to-search
Social-to-search is buying visitors from ads on social platforms such as Facebook, Instagram or TikTok and sending them to a page that earns from search ads.
Social-to-search uses paid social as the traffic source. The operator runs ads in social feeds and short-video apps, and lands the people who click on a content page or keyword page that earns from a search feed.
Social platforms offer two things arbitrageurs value: enormous audiences and algorithms that learn. If the operator reports each ad click on its page back to the platform with a Conversions API, including how much it earned, the platform can seek out more people likely to produce revenue. This is value-based bidding, and it is a large part of why the model grew.
The risks are equally clear. Social users were not searching for anything, so intent must be created by the ad, which tempts buyers toward exaggerated claims. Social platforms enforce their ad policies with sudden account bans. On the feed side, Google's rule that the complete ad wording be passed in referrerAdCreative covers social creatives explicitly, including text in images, video and audio. An ad that could not be shown honestly to the feed should not be run.
An example
For example, a short video ad about home battery prices costs $0.15 a click. 35% of visitors click a related search and 55% of those click an ad paying $0.90. Revenue per visitor is about $0.17.
