Search Engine Optimization is a process of promoting a website worldwide through the web. SEO, which is done on the world level, is known as the global search engine optimization and the SEO, which is done for the promotion and marketing in the local geographical areas. Global SEO focuses on large-scale generic keywords to get traffic to a website. Local SEO focuses on generic keywords modified with a local environment to get specific traffic from an area to a website. Both keywords and IP addresses are the two important factors, which affect the search results. However, it is a fact that the keywords and IP addresses are used in both the areas are totally from each other and have their own relevancy.

The keywords, which are used in local search engine optimization, are a bit different and unusual than it is used in the global search engine optimization. While a global indexing might show lots of traffic, it in all probability is not going to result in sales because people are not willing to drive from one state to another just because any website showed up in that list. Local SEO make use of locally modified search phrases and keywords, as well as local results listed in the major engines among specialized local sections. Google Places/Maps is an example of this theory. If any website is not listed in the Places section, the webmaster should mark his company to be found locally. Language is also a factor to maintain a difference between the two. People who find their suitable products or services they never go for a global search.
