Often the line between pay per click advertising and paid inclusion is debatable. Some have lobbied for any paid listings to be labeled as an advertisement, while defenders insist they are not actually ads since the webmasters do not control the content of the listing, its ranking, or even whether it is shown to any users. Another advantage of paid inclusion is that it allows site owners to specify particular schedules for crawling pages. In the general case, one has no control as to when their page will be crawled or added to a search engine index. Paid inclusion proves to be particularly useful for cases where pages are dynamically generated and frequently modified.

Understanding the working mechanism of social algorithms is not a piece of cake. The algorithm for each social platform works differently. For instance, on Facebook, a core factor that affects the rankings of a post is its relevancy score, whereas on YouTube the total watch time of the video per session decides whether a video enters a ‘Recommended Video’ section or not.
Organic-search traffic is the only search traffic you should be interested in. This is the traffic you get without any direct action on your part. It’s not something you can achieve with ease, though. The statistics say that 83 percent of organic clicks go to the first four results under most categories on search engines. So, to see your site attain that status, lay the foundations well in advance for the traffic you want.
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.
