I'm currently trying to learn SEO and in the meantime try to understand keyword difficulty better. I know that I can't trust a single number that LongTailPro or KeywordRevealer spits out since it's a lot more complicated but I've got to a point where I've read mixed thoughts about big ecommerce sites in the top 10. Some say it's a sign that no websites / articles are optimized for that keyword and it's a good sign, but others say that you should avoid keywords when you see only huge ecommerce sites in the top results. So basically, I've found a keyword with quite good specifications and I intend to make an amazon affiliate site about it. Obviously it's a [producty category] keyword so there are other sites selling it apart from amazon The top 10 is looking like this: 1. Walmart 2. Walmart 3. Target 4. Tesco 5. Amazon 6. Amazon 7. eBay 8. Slate.com (it's an article) 9. Overstock 10. Kmart Keyword Revealer says 17 (Extremely Low Comptetition) keyword difficulty, there is only 1 site that has the KW in the url, 3 that has it in their title, 1 in the description and 1 in <H1> tags. While it looks extremely promising, I'm a little skeptic about those sites. What is your experience with sites like these? What would you suggest? Thanks for your help!
