The objective of (SEM) is to drive traffic to your website with the intent of converting those visitors into customers. With SEM, it is important to have your business site listed near the top of the search engine rankings since very few internet users will actually look at search results beyond the first couple of pages. SEM can be divided into two categories: organic and paid. Both are important.
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.
SEO may generate an adequate return on investment. However, search engines are not paid for organic search traffic, their algorithms change, and there are no guarantees of continued referrals. Due to this lack of guarantees and certainty, a business that relies heavily on search engine traffic can suffer major losses if the search engines stop sending visitors. Search engines can change their algorithms, impacting a website's placement, possibly resulting in a serious loss of traffic. According to Google's CEO, Eric Schmidt, in 2010, Google made over 500 algorithm changes – almost 1.5 per day. It is considered wise business practice for website operators to liberate themselves from dependence on search engine traffic. In addition to accessibility in terms of web crawlers (addressed above), user web accessibility has become increasingly important for SEO.
By 2014, people were seeing approximately 5,000 advertisements every day, according to statistics from the Content Marketing Institute. Faced with that kind of competition for an audience’s attention, there are two common approaches: paid marketing and organic marketing. Paid marketing involves assigning a budget to your advertising campaign and paying various platforms for the promotion.
Today, organic marketing does not exist in Social Media and in SEO. Even if you somehow manage to rank first on the search results for a specific word, how many resources did it take you? how many resources will it take you to maintain this ranking against eager competitors? your time is money, and many businesses spend way too much time trying to rank for keywords or trying to grow their social media page organically.
Website owners recognized the value of a high ranking and visibility in search engine results, creating an opportunity for both white hat and black hat SEO practitioners. According to industry analyst Danny Sullivan, the phrase "search engine optimization" probably came into use in 1997. Sullivan credits Bruce Clay as one of the first people to popularize the term. On May 2, 2007, Jason Gambert attempted to trademark the term SEO by convincing the Trademark Office in Arizona that SEO is a "process" involving manipulation of keywords and not a "marketing service."
Organic is what people are looking for; the rest of these simply put things in front of people who may or may not be seeking what you offer. We know that approximately X number of people are looking for Y every day. So if we can get on front of those people, we have a much greater opportunity to create long-term relationships and increase our overall ROI.
