Hi everyone,
Here is our comparison with LTP. I wasn't sure how to normalize LTP's numbered difficulty ranking system. On the LTP site, the owner basically says that keywords under a score of thirty would be good for niche website. Given that statement and the range of difficulty I had, I chose the following for the ranking system - Greater than 60 is Very Hard, 50 - 60 is Hard, 30 - 50 is Moderate, 20 - 30 is Easy, and 1 -20 is Very Easy.
I only did 245 keywords, and I pulled this data yesterday using UNF v.2.0.2.9 and LTP v.2.4.5. The results found that UNF ranked 124 KWs more difficult to rank for than LTP, i.e. it would be harder to rank on G for this KW. For 92 KWs, UNF ranked them the same difficulty as LTP. For 26 KWs, UNF ranked the KWs less difficult to rank for than LTP.
All three of us (UNF, TT, LTP) provide similar functions (albeit it we go about it different ways), and, for the most part, our competition analysis is in line with one another. UNF would probably rank some keywords more difficult since it is seeing difficulty for getting into the top 3 search results and not the top 10.
If any of you want to see the PDF with the raw data, send me a PM and I'll shoot it over to you.
