[Dan]

Right now we utilise Time On List as a large part of the weighting in the Top 100 ranking system.

Time On List refers to the amount of time (the lowest breakout it weeks, but it dates in months and years too) that a directory has been on the actual IVS lists. So a directory may be 5 years old, but if it has only been on the list for 2 years then it is the 2 years that we count.

We did this originally for a number of reasons, as many directories converted to an SEO friendly nature years after being established. It was fair to the original SEO friendly directories to be recognised and given their due weighting.

After having the ranking system fixed, I can now see that using TOL in this fashion has peaked. What this means is that now that the Top 100 list is well established (it was created in 2007), the directories who were new on the lists back then, but who were very old, have caught up in the ranking system after now being on the lists for a long time. So this factor has been diminished somewhat. Ongoing, very little will change because the age factor, has "in effect" maxxed out. Something that I had planned it to do all along.

Also because directories have been forced to evolve over time to remain relevant and to adhere to search engine and market changes, I believe the TOL rating (which really was centred around the whole "seo friendly" movement) should be replaced with Directory Age.

Now, Directory Age shouldn't be confused with Domain Age. An 8 year old domain that has had a directory on it for 2 years, has a directory age of 2 years. Claiming 8 years of age is not only incorrect, it is tantamount to lying.

This value too, will max out at some point. You are probably looking at something like 10 years before that value also begins to plateau. Right now I think the TOL peaks at about 5 years (meaning a directory added in 2007 will technically have the same value as one added from the starting date of 2004 when the original SEO friendly directory lists went live).

Directory Age, takes a lot more work to determine, as it is a manual factor that would have to be added to each directory in the list. Sites like the web archive help, but don't always have the data particularly if site owners are blocking the crawler.

To simplify things I would probably do it by year... Meaning "year established". So if it was Feb 2004, or Dec 2004, it would simply be 2004.

I'm currently compiling a lot of this data for a big project that I am working on, so once that is done I will look to implement it all as part of the system. Probably in a few months time.

Thoughts?
