My favorite style in this is article marketing. You create anchor content on your website or blog, then you build authority-content links to that content, effectively driving up the visibility. I've used this single strategy to rank hundreds of keywords in the #1 spot on Google, and I would highly recommend that if you're going to learn any marketing strategy, that you get really good at this one.
Search engine optimization (SEO) is the process of improving the visibility of a website or webpage on a search engine results page (SERP) so as to make a company’s website more discoverable (i.e., on the first page/s), thereby driving traffic and sales. Tedious, involving technical and business decisions, and not guaranteeing results—it nonetheless provides lasting benefits.
On the other hand, all of the results for the PageRank engine (aside from a single secondary listing) link to the homepage of major American universities. The results are much more logical and useful in nature. If you search for “university,” are you going to want the homepages for popular universities, or random subpages from a sprinkling of colleges all over the world?

As with offline advertising, industry participants have undertaken numerous efforts to self-regulate and develop industry standards or codes of conduct. Several United States advertising industry organizations jointly published Self-Regulatory Principles for Online Behavioral Advertising based on standards proposed by the FTC in 2009.[109] European ad associations published a similar document in 2011.[110] Primary tenets of both documents include consumer control of data transfer to third parties, data security, and consent for collection of certain health and financial data.[109]:2–4 Neither framework, however, penalizes violators of the codes of conduct.[111]
CPC (Cost Per Click) or PPC (Pay per click) means advertisers pay each time a user clicks on the ad. CPC advertising works well when advertisers want visitors to their sites, but it's a less accurate measurement for advertisers looking to build brand awareness.[63] CPC's market share has grown each year since its introduction, eclipsing CPM to dominate two-thirds of all online advertising compensation methods.[24]:18[62]:1
