But keywords are not just about SEO. They at the heart of a company's marketing campaign at its most granular level. Do our customers love our product because it is fast-acting or because it is long-lasting? Are we cheap or the best? Do we provide people with ideas or with help? If you can't immediately identify the most important keywords for your company, it is doubtful that you can effectively market your products and services to your target audience. The following guide will provide you with 5 ideas to keep in mind when you are selecting keywords on which to build your online marketing.

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.[22] 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.
While SEO allows you to optimize your website for a greater chance in appearing higher in search results, and online advertising allows you to send promotional content to the target audience of your choosing, SEM combines both benefits as your content is both optimized for higher search rankings and is placed primarily in front of audiences who are most likely to convert when they click on your ads.
