Webmasters and content providers began optimizing websites for search engines in the mid-1990s, as the first search engines were cataloging the early Web. Initially, all webmasters needed only to submit the address of a page, or URL, to the various engines which would send a "spider" to "crawl" that page, extract links to other pages from it, and return information found on the page to be indexed. The process involves a search engine spider downloading a page and storing it on the search engine's own server. A second program, known as an indexer, extracts information about the page, such as the words it contains, where they are located, and any weight for specific words, as well as all links the page contains. All of this information is then placed into a scheduler for crawling at a later date.
Companies often use email marketing to re-engage past customers, but a “Where’d You Go? Want To Buy This?” message can come across as aggressive, and you want to be careful with your wording to cultivate a long-term email subscriber. This is why JetBlue’s one year re-engagement email works so well -- it uses humor to convey a sense of friendliness and fun, while simultaneously reminding an old email subscriber they might want to check out some of JetBlue’s new flight deals.
By relying so much on factors such as keyword density which were exclusively within a webmaster's control, early search engines suffered from abuse and ranking manipulation. To provide better results to their users, search engines had to adapt to ensure their results pages showed the most relevant search results, rather than unrelated pages stuffed with numerous keywords by unscrupulous webmasters. This meant moving away from heavy reliance on term density to a more holistic process for scoring semantic signals. Since the success and popularity of a search engine is determined by its ability to produce the most relevant results to any given search, poor quality or irrelevant search results could lead users to find other search sources. Search engines responded by developing more complex ranking algorithms, taking into account additional factors that were more difficult for webmasters to manipulate. In 2005, an annual conference, AIRWeb, Adversarial Information Retrieval on the Web was created to bring together practitioners and researchers concerned with search engine optimization and related topics.
For example: If you sell household electronics and your paid ad promotes your selection of noise-cancelling headphones, your landing page should feature your noise-cancelling headphones. Directing people to your homepage instead, where they’ll need to sift through your product categories or do another search, will lead to frustration and a poor chance of getting the sale. http://www.youtube.com/embed/7bNPg8UbhaE
Consider the age of your business. If you just opened your business and launched your website, it’s going to take time to develop your SEO and begin to appear organically in the search. While that doesn’t mean you shouldn’t put together an SEO strategy, it does mean that you could benefit from an SEM strategy until you build your SEO. SEM is an effective way to drive traffic while building organic SEO. http://y2u.be/7bNPg8UbhaE
