Awareness and Branding. Visibility is one thing and being top of the line is another. The more that people see you, the higher your chances of being remembered and that keeps awareness among potential customers. Same goes with branding. Once you start linking your business with certain terms and keywords which are deemed positive for you, its effect will most likely be beneficial for your business and can, later on, lead to a sale.
Additionally, knowing how your SEO is performing can help you make the necessary changes over time to keep your rankings high. Look around for a keyword tracking tool to help you track how your SEO is performing. It’s typical for your ranking to fluctuate from week to week and even day to day. Look for a general upward trend from month to month that shows that your efforts are successful.
SEO techniques can be classified into two broad categories: techniques that search engine companies recommend as part of good design ("white hat"), and those techniques of which search engines do not approve ("black hat"). The search engines attempt to minimize the effect of the latter, among them spamdexing. Industry commentators have classified these methods, and the practitioners who employ them, as either white hat SEO, or black hat SEO. White hats tend to produce results that last a long time, whereas black hats anticipate that their sites may eventually be banned either temporarily or permanently once the search engines discover what they are doing.
Retargeting: Each platform offers retargeting to help you reach people who’ve already visited your website. The benefit of retargeting is that a conversion is more likely when you know the prospect is interested. You might also upload an email list and use Facebook Custom Audiences to serve ads directly to subscribers. In the following example, we see two ads that show in the Facebook sidebar to reach former web visitors.
On April 24, 2012 many started to see that Google has started to penalize companies that are buying links for the purpose of passing off the rank. The Google Update was called Penguin. Since then, there have been several different Penguin/Panda updates rolled out by Google. SEM has, however, nothing to do with link buying and focuses on organic SEO and PPC management. As of October 20, 2014 Google has released three official revisions of their Penguin Update.
Social media is adopting its own form of SEO in a way that promotes a positive user experience. The way this algorithm works is by putting your posts in a pool as small as one percent of your followers. If those people engage with the content, then it gets introduced into a larger pool. Slowly but surely, more and more people see it, but only if it’s engaging.
Everyone wants to rank for those broad two or three word key phrases because they tend to have high search volumes. The problem with these broad key phrases is they are highly competitive. So competitive that you may not stand a chance of ranking for them unless you devote months of your time to it. Instead of spending your time going after something that may not even be attainable, go after the low-hanging fruit of long-tail key phrases.
Google claims their users click (organic) search results more often than ads, essentially rebutting the research cited above. A 2012 Google study found that 81% of ad impressions and 66% of ad clicks happen when there is no associated organic search result on the first page. Research has shown that searchers may have a bias against ads, unless the ads are relevant to the searcher's need or intent 
Search engine marketing (SEM) is a form of Internet marketing that involves the promotion of websites by increasing their visibility in search engine results pages (SERPs) primarily through paid advertising. SEM may incorporate search engine optimization (SEO), which adjusts or rewrites website content and site architecture to achieve a higher ranking in search engine results pages to enhance pay per click (PPC) listings.
Use Facebook Insights to gain a better understanding of your Facebook fans. You can then target specific messages to meet the specific needs of subsets of your audience. For example, if you’re selling clothes and have written an article on the latest fashion trends for women, you can target your post to appear in the news feeds of women who have expressed an interest in clothes. Targeting options include Gender, Relationship Status, Location and Interests, etc. To target your Facebook post, simply click the targeting icon at the end of your post before you click Publish.
The Google, Yahoo!, and Bing search engines insert advertising on their search results pages. The ads are designed to look similar to the search results, though different enough for readers to distinguish between ads and actual results. This is done with various differences in background, text, link colors, and/or placement on the page. However, the appearance of ads on all major search engines is so similar to genuine search results that a majority of search engine users cannot effectively distinguish between the two.
