Because so few ordinary users (38% according to Pew Research Center) realized that many of the highest placed "results" on search engine results pages (SERPs) were ads, the search engine optimization industry began to distinguish between ads and natural results. The perspective among general users was that all results were, in fact, "results." So the qualifier "organic" was invented to distinguish non-ad search results from ads.
Search engine marketing encompasses a range of activities all centred around making your website more visible when someone uses a search engine. If someone is looking for your business on the internet, it is vital your website appears prominently in the search engines’ results pages, or it will never deliver the value to your business that today’s economy demands.
With more and more content being created on Facebook every day, organic reach is steadily declining. That’s why you might want to consider using Facebook’s paid advertising options to promote and increase the reach of your posts. While organic posts only get shown to your own Facebook fans, paid ads allow you to target people who have not liked your page but have similar interests and/or demographics.
Look at the different search engines (sources) that drive traffic to your site to determine where you want to invest your resources. For example, if you're getting an overwhelming amount of visitors and revenue from a particular search engine, that's an obvious source of profitable traffic and an area in which you might want to make further investment; but you might also find another search engine that delivers only a few visitors, but ones who represent a very high Per Visit Value. In this latter case, you might want to increase your spend in that area to drive more of those high-value visitors to your site.
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.
