hi i am new in seo field, so i have a confusion about what is the KEI(Keyword effectiveness index ) in keyword research and what is the formula to find . thanks for help
KEI for a keyword is the ratio of the search volume of a keyword to the competition of that keyword KEI= Search Volume Of a Keyword/Competition of that keyword
Kei stands for keywod effectiveness index. the best keywords are those that have many searches and that don't have much competition in the search results. Actually it is a formula which states that “number of monthly searches†squared divided by “completing pagesâ€. It is used for calculating value of keyword phrases that target the blog or website. Example: suppose the number of searches for a keyword is 486 per month and Google displays 214,234 results for that keyword, this value can be obtained by using google adwords keyword tool. Then the ratio between the popularity and competitiveness for that keyword is 486 * 486 divided by 214,234. In this case, the KEI 1.10. The higher the KEI, the more popular your keywords are, and the less competition they have. That means that you might have a better chance of getting to the top.
Not sure about the formula, but that was invented about a decade ago and was used with Wordtracker's subscription service. Unless they've updated it it's probably outdated (IMO), so is search competition numbers that so many people recommend. A better way of determining the competition is analyzing the the first page in the SERPs, that's the only page that matters, the numbers drop drastically for the subsequent pages. If you don't think you can beat several listings on the first page I'd look for another keyword (backlinks, PR, how well optimized, DMOZ or Yahoo listed, etc.) Download the trial version of MarketSamurai or the free version of TrafficTravis to get a better view of the competition.
The Keyword Effectiveness Index (KEI) compares the number of times a keyword has been searched for with competition (the number of pages that contain the exact keyword phrase within at least one of its incoming links, known as 'All in Anchor'). So: 1 - The KEI figure will go up when the keyword's popularity increases. 2 - The KEI figure will go down when there is more competition for a keyword. Here's the formula: KEI = (Searches ^ 2) / In Anchor When KEI was first developed, it was easy to say that a KEI figure of over X or Y made the keyword a good one. Because the SEO industry has grown, and because there is an enormous amount of content now published on the Internet, all jostling for space in the SERPS (search engine ranking pages), it's better to view KEI as a relative figure, particularly when looking inside a niche. In some niches a KEI of 10 might be the highest number you see. In others (particularly when working with Google data with higher search counts), you might see a KEI figure in the millions. Remember, it's all relative. https://keywords.wordtracker.com/help/metrics_explained#competition
