Internet marketing professionals refer to search that isn’t organic as paid search. Instead of organically, or naturally, reaching the top of the search results for a particular keyword, businesses can pay to get noticed. So, paid search is a bit like doing a local endorsement, TV ad or radio spot—but for the internet. When a consumer types in a search term that you’ve incorporated into your campaign, your ad will show up at the top of search page results, above the organic results. Sometimes, your ad may appear in the sidebar. Only if the consumer clicks on your ad do you pay anything.
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.
PPC gives you the ability to fix your daily budget depending on how much you’re willing to spend. And since you can start off with a small amount, you don’t have to put a heavy investment at stake before testing the waters. Once you know a certain campaign is giving you a good return on investment, you can ramp up your budget and increase your ad spendings without worrying about incurring losses.
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.
