Paid social media is anything that is influenced by advertising dollars spent. Any post in your news feed that has the “Sponsored” tag is paid social media. If you then “like” that post, that is considered a paid reaction. Paid social media includes boosted posts, ads optimized for clicks, lead generation forms, video ads, among other objectives, and can be targeted by a variety of demographic and behavioral factors.
Website owners recognized the value of a high ranking and visibility in search engine results, creating an opportunity for both white hat and black hat SEO practitioners. According to industry analyst Danny Sullivan, the phrase "search engine optimization" probably came into use in 1997. Sullivan credits Bruce Clay as one of the first people to popularize the term. On May 2, 2007, Jason Gambert attempted to trademark the term SEO by convincing the Trademark Office in Arizona that SEO is a "process" involving manipulation of keywords and not a "marketing service."
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
