Keyword Effectiveness Index = Misleading
Ok so I’m going to go into some detail about SEO here. The Keyword Effectiveness Index is basically calculated by the number of searches for a keyword divided by the number of websites containing the keyword. Its meant to give you an idea of how much competition there is. It does, but it doesn’t help.
The next stage is to only consider direct competition, the way to do this is by analysing anchor links with the keyword in, so replace the number of websites with the number of competing sites. I’ve seen this in a few places, I’m not sure what it is officially called, but its slightly more useful than the KEI, David Viney calls it KOI, so I’ll call it that.
So lets say you have a keyword with a crap KEI (low) but with a high KOI, great, but you may still have over 100,000 competing sites. So I think the next stage is to look at the top 20 in Google, David Viney recommended taking the page rank of ranks 18-22 for a keyword and then average the page rank between them to find the page rank you need to appear in the top 20.
But still how much help is that? We’re still ignoring the most important part of this whole exercise, the conversion rate. So lets say you get number one rank for the keyword “how to cut grass”, but you are trying to sell grass, so you don’t get a single sale, this is where the KEI/KOI/Page Rank difficulty assessment fails.
So I intend to create some kind of new measurement, alongside my keyword research for my new COD book.
