Pinterest combines the advantages of Google and Facebook advertising. Pinterest ads are engaging, like those on Facebook and Instagram, but it uses specific keywords to make sure your ads are highly relevant to your target audience, just like search engine ads.
This in-built search results algorithm, called Smart Feed, is one of the key reasons why Pinterest ads can be so much more effective.
While Facebook or Instagram posts quickly become dated, because organic pins and ads are better categorised, they can remain relevant for years to come.
