For more clearly what the mean of Search engine volume and number of competitors let’s we look more deeply:

1. SV (search volume) = is the approximate number of search these keywords in 1 month. For example in case you want to search for SV from keyword “free money” …

The first step is to go to http://freekeywords.wordtracker.com, and type in “free money“, then you will get results which is approximately 1741 for “free money” keywords. This means there is a 1741 search everyday for the keywords “free money“. This also meant 1741 X 30.5 = 53,100 per month (approximately monthly count). So this 53,100 digits number is the SV (search volume) for keyword “free money.”

2. # Of Competitors = number of the web that contain keywords that we wish to find her KEI. Here the easy way… you open http://www.google.com, then type the keyword “free money”. After that you could see result in this part: “Results 1 – 10 of about 187,000,000 search results for free money. (0:24 seconds)“… So the number 187,000,000 # is the competitors for the keywords “free money.”

Well so we got all the recipes for calculating the KEI… Now we just enter it into the formula:
