“Thanks for clarification, James. I did random check as per report, I had 700 links added in October and 100 recently, how long do I have to wait before they are indexed by the search engines or other tools?
My site is registered on Dmoz but not Yahoo. Yahoo charges $299 pa.
”
Well it depends really on how often search engines and tools visit the site to determine when it will index thus making it hard to say.
Now because some of these are directories I am thinking most of the links that you got are from directories and some tools just dont list these in a blacklink reports... Don't ask my why they just don't. I have submitted sites to over 2000 directories and it only shows up a few in my tools. Now if these were better links then I would expect them to show up but because they are not I wouldn't be too worried.
Thats great that your on dmoz, and yeah yahoo does charge which why it adds more value because not everyone is going to pay for that.
Let me just say something because people on here can seem to come across as very scared of even a hint of spammy/blackhat type links. It is unlikely that it will hurt you (especially you with only 800 links) google is not going to throw you out of its search engine because of that. now if you got thousands upon thousands in a short space of time then yeah then it will raise a flag.
I just don't want you to lose sleep over it (in your case). Think about it, if I was your competitor and I knew all I had to do was get a few spammy links to your site then google will through you out.. then (depending on the morals of the competitor) I could easily just take you out. Instead google just doesnt value the links. Thats all.
