Search engines use complex mathematical algorithms to guess which websites a user seeks. In this diagram, if each bubble represents a website, programs sometimes called spiders examine which sites link to which other sites, with arrows representing these links. Websites getting more inbound links, or stronger links, are presumed to be more important and what the user is searching for. In this example, since website B is the recipient of numerous inbound links, it ranks more highly in a web search. And the links "carry through", such that website C, even though it only has one inbound link, has an inbound link from a highly popular site (B) while site E does not. Note: Percentages are rounded.
When it is time for your organization to start creating new products or enhancing items already on your product line, organic search can maximize your efficiency and gauge market demand. You will be able to see which products are sparking the most interest through increases or decreases in organic search. You can then take the information from the Data Cube and compare it to trends within your own sites and the performance of your competitors to create a product line that maximizes your investment.
Network marketing: Network marketing companies have a great business model (for those who own the company), because they only pay their sales people (a.k.a. “independent business owners”) when they make a sale or recruit another person. They only pay on performance. So to sell a bunch of product, the direct sales company really doesn’t go directly to the consumer through TV or magazine ads or similar methods that could easily cost millions; instead they go indirectly through their sales people and only pay for the word of mouth advertising as a commission on a product sale. It’s really savvy business strategy that’s low-risk and high-reward, if it spreads far and fast enough by emotionally exciting the distributors. Distributors are heavily using social media like Facebook, YouTube, blogging and the like to generate sales and grow their network online.
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.
