There are a lot of elements of search engine optimization that are important. None are more critical to the time and effort exerted in a program than proper keyword research. Search engines index and list web site pages based on the content of words on the page in a concentration that indicates the topic matter. The actual searches are done by submitting keywords that the search engines will compare to their vast indexes and present the most relative pages that contain those keywords.
For that reason, the first stages of any search engine optimization program involve keyword research. The keywords chosen to be used, or even just the words used in the site content will determine what sort of indexing is done on the site and how it ever gets presented in search engine listings. Poorly chosen keywords, or poorly concentrated topical words on the site pages will limit the possibilities of ever being found in the search engine listings. This is why there is a very large industry that concentrates on building the lastest and greatest keyword research tools.
Initially, keyword research is done by interviewing the business owner, his employees who communicate with the customers, and possibly even a few customers. Beginning to get a sense of the words used within the industry presents a starting point for keyword research. But, have you ever gone to a vendor or merchant to ask about a particular product and been presented with a littany of industry terminology? Of course you have. Just about every industry has their industry lingo and semantics that their customers are usually not aware of. In many cases, the customers have their own terms for the products and services. These terms are the most important ones when a business tries to reach new customers.
Keyword Research is then done using a variety of tools that typically exist online. Large databases are maintained by a variety of companies that track online searches and the keywords that are used. What specific keywords are used and how often the keyword is searched is recorded in a huge database. When the keyword research tool is used to search for possible keywords, the database is searched, indexed, and a multitude of possibilities is spit out. It is the Keyword Researher's job to sort out all this information.
