An index term, in content retrieval, is simply a word that captures the meaning of an individual subject, topic, or description in information retrieval. Index terms constitute a standardized vocabulary for use in electronic online bibliographies. When a search results in many different subject terms (all of which can be called keywords), the information may take quite some time to sort through all the terms and rank them according to their frequency in use relative to the topic, and thus relevance. This, obviously, increases the overall quality and relevance of any retrieved data.
So, how do we perform quality keyword research? Keyword research is carried out in several different ways. Many online SEO consultants use meta descriptions, which provide information about the keyword and provide hints about the optimal number of times it should be used. Meta descriptions also specify what keywords should not be used because they are too competitive.
Another way to perform keyword research is to select keywords based on the primary keyword. For example, the keyword “adSense” is most likely to appear in a meta description, because it is the primary keyword of an AdSense advertisement. The meta description, therefore, is optimized around the primary keyword, because it is the most important aspect of the website. It is then important to select the proper number of times this keyword should appear, as well as the ideal density, so that the best possible optimization for search engines occurs.
Keyword volume is another important consideration. Online keyword tools such as Google Keyword Research Tool and WordTracker allow any website owner to find out how many times a keyword appears on a page. The tool displays the search volume by month for each selected keyword, and gives a percentage chance of how often that keyword appears, on a monthly basis, in natural search volume. However, even when a keyword appears in very high search volume, there is usually no significant traffic potential, and the website owners will probably not achieve their traffic potential. This is why it is important to select the appropriate number of keywords that will generate enough traffic to achieve the desired traffic volume.
A keyword is only important if it has enough power to move the website one step up in the search engines. The higher the ranking of a website, the more likely it will attract more traffic. In general, it is better to have one word keywords than a cluster of words because keywords with power will be easier to rank for and harder to rank for. One word keywords can be very good if they have low competition and very low bid prices, but if those keywords have very high competition and very high bid prices, they will not achieve their traffic potential.
A keyword is only useful if it is understood by the search engine and can generate enough traffic to achieve the desired ranking. Keyword research includes several different components, such as keyword research tools, keyword analysis, competitor analysis and search engine optimization (SEO). These are important aspects to help the user find what he/she is looking for. The best way to start a keyword research is to go directly to the source, which is the search engines. Many companies offer keyword research and analytics services, which can give you a good idea of the power and profitability of your keywords, which is essential in making important business decisions.
