What is the Keyword Effectiveness Index (KEI)?

KEI is the vital term when calculating the value of keyword phrases to target your blogs, websites. It is simply an indicator of how popular a search phrase is and how competitive the market is for this search phrase. The formula is simply expressed as (Number of monthly searches) squared divided by (Competitor Pages). It’s a simple math equation, but it says a lot about keyword competition for SEO experts, online marketers, and most likely bloggers. Let’s investigate the KEI formula further now.

How do we determine the popularity of a keyword?

We simply look at monthly searches on a specific search engine. You can use the Google AdWords keyword tool to determine this value. Many novice keyword researchers think that the most popular keyword is the best option to target. In fact, it is wrong. The more search means more competition.

So what is the competition in terms of search engines?

Competition is determined by the pages competing for a keyword phrase in search engines. If you search for a general keyword (such as “auto loans”) several hundred thousand times a month in a search engine, there will naturally be several million pages competing to show up in search engine first page results. .

Our goal should be to find moderate searches with small to moderate competition. I will give a concrete example. Let’s say keyword phrase A is searched 100 times a month and 10 pages of the competition. Another keyword phrase B is 1000 times a month and 100 pages in competition. If we don’t square these terms and we simply divide; They would give the same results for KEI!

Note that according to our KEI (squared) formula, B is much more logical to target. Why? Because 100 times a month is a small number, it won’t actually generate much revenue unless it’s a high-priced keyword.

While calculating KEI, it is advisable to search for keyword phrases that are searched at least 1000 times per month for a serious investment in SEO.
