Google may very well discount that link since after all it is paid. I added a site there once and didn't see any difference of any kind. You can sign up and see for yourself, there is a free trial period, but be sure you cancel before the trial is up or they will charge you and say it is nonrefundable.
I've submitted a few sites there ... in my early days!! - wouldn't do anymore! as you can get better links far cheaper to boost your page rank, just go onto the link sales forum - ** remember page rank is only a small portion of SEO - KEYWORDS are so, so important... (just adding my penny)
I submitted my real estate site to BOTW a while back and got a PR5 link. My site went from PR1 to PR3 and I hardly got any other links and none with enough PR to warrant that increase. I definitely think it was the BOTW listing that gave that site the most PR boost. This is an editorially-approved listing so Google doesn't frown upon it like a paid link and it should increase your Trust Rank since crappy sites won't get into BOTW. I recommend it.
It's all about getting a balance. You're not going to notice a jump from just one link in a directory like that. But if you don't have any directory listings, you should get a few. These are some of the big boys DMOZ, free - good luck on the wait. They should start charging $200 and pay people to actually edit the directory Yahoo $299 - expensive - but almost as good as dmoz and instant inclusion Startingpoint $100 year Business.com $199 year BOTW is considered good too, a little lower down. If you are a big company chances are you've already submitted to those.
Why not? There's nothing in the PageRank algorithm that says that one high pr link is not going to increase your pr, especially if you are starting from pr1. In fact, it says the opposite: you can get a PR boost from any link - that's how the PR algo works. I'm not sure I would include dmoz at the top of the list anymore with all the issues with corrupt dmoz editors. I've heard a lot of talk that Google isn't putting as much trust in dmoz anymore. I definitely agree with Yahoo dir and business.com. Haven't checked out Startingpoint yet but I definitely will.
I wish M$ would get their stuff together and get their sbd directory back on track. It was a good deal IMO.
I think the other already said what I wanted to say... I didn't submit to BOTW, there are a lot more less-costly alternatives out there.
Oops - I was thinking of a boost in rankings. Yea I guess if youre a PR1 it would help. Of course the page your link on needs to have that PR - not the homepage of the site...sometimes internal pages are pr0 on a pr 6 site.
I strongly believe the reason one of my sites never dropped to #3 in Google is due to dmoz list even though I have been promoting it since the keyword was searched at overture only 300 times in a month. (now over 1100)
