Since many people had questions on what are the best dir to submit to I will make my list available of the creme de la creme directories Dont expect to find these dir in the lists people submit to normally They are mostly not easy to get into and some may even require some social engineering or special tact and convincing regardless the effect of having such links will show as a smile on your face when serps change in your favor. Data on what exactly makes them valuable has been included and can be sorted Power directory list Q & A: How did you assess your 1-5 significance rating or is it more of a personal gut feel? We assigned the values according to the following factors: amount of unique domains linking in, total Inbound links, .gov and .edu inbound links, domain age, pagerank, Pages in Google index, Pages in Yahoo index, domain expiration date, compete rank, Dmoz listed etc. The amount of relevant link hubs linking to this site ( found with a visual semantic browser and the extracted data and overlapping links from authority hubs ) this combined and my own reasoning of perception of value. Since it is not the most precise it is just devided into 5 ratings - If you think I missed one (of your own) please feel free to add it here by replying : )
