PPC (paid search marketing): PPC (pay per click) advertising involves paying to have search engines display your website offer in or alongside search results. For example, Google's Adwords program will display your ad at the top or right side of the search results page (placement depends on many factors including keywords and quality of ad). Google will also feed your ads to websites running its Adsense program. There are other types of PPC marketing, such as Facebook Ads. In PPC advertising, you pay each time someone clicks on your offer. Paid search differs from organize search in that you're paying to have your website or offer displayed higher in search results.
Organic traffic, on the other hand, are those visits which are tracked by another entity — usually because they have arrived through search engines — but also from other sources. Hubspot’s definition emphasizes the term “non-paid visits,” because paid search ads are considered a category of their own. But this is where the lines between direct and organic start to get little blurry.

Social media changes so quickly that it can be difficult to keep up with terminology and best practices. One of the biggest points of confusion that I see with business owners and marketers is the distinction and strategic balance between organic and paid social media. Understanding this is essential to creating a successful social media marketing strategy.  Organic and paid social media have distinct advantages but work best when implemented together. Every popular social media outlet has paid and organic elements, but since Facebook is the largest social network (both in terms of users and advertisers) I’m going to focus on that platform in this article.

In 1998, two graduate students at Stanford University, Larry Page and Sergey Brin, developed "Backrub", a search engine that relied on a mathematical algorithm to rate the prominence of web pages. The number calculated by the algorithm, PageRank, is a function of the quantity and strength of inbound links.[21] PageRank estimates the likelihood that a given page will be reached by a web user who randomly surfs the web, and follows links from one page to another. In effect, this means that some links are stronger than others, as a higher PageRank page is more likely to be reached by the random web surfer.
Organic social media is anything that happens on social media without paid promotion. When you post as your page but don’t put any money behind this post to “boost” it, you are creating an organic post. If you comment on a business’s post in your news feed, and the “Sponsored” tag does not appear on the post, that action qualifies as organic. In other words, organic actions occur on non-ads.
Now, it is not that these sites are not interested in Google users. In fact, they have hired us to help them increase their share. However, they are getting so much traffic from sites like Facebook that it seems there is less urgency about attracting this traffic and less willingness to change the site to meet organic standards. Not long ago, sites would urgently and unquestioningly abide by Google’s standards to court that traffic.
