Why are most dofollow links not showing on backlink checks?

Hi, ive been building backlinks everyday manually and most of them are dofollow but they are not showing up on backlink watch or iwebtool, would anyone know why they might not be showing up?
I submit about 2 or 3 backlinks per day and most of them are dofollow social bookmarking sites or article sites and i make sure that i write good unique descriptions for each one.
I have a fairly new site and i would have built hundreds of backlinks over time, but no matter how many i build, the backlink checkers only say around 20 and that's it.

 

Hello,

Try to check your back links on www[dot]rapidsitecheck[dot]com it will get maximum here.

Thanks

 

Ok, thanks for that.

 

It says 48 backlinks but i know ive done way more then this. My site is only 6 months old, would this have anything to do with more dofollow links not showing up, or does this have nothing to do with it? Does the new site sandbox theory have any effect on backlinks not showing up?

 

The sites have to get indexed and crawled to show up.

 

Yes the backlink source must be indexed.
And you have to wait for some time

 

You're being a little impatient. You may also want to make sure that the sites are really dofollow by using seofox or nodofollow. I know a lot of blogs say they are dofollow, but when I check the links, they are actually nofollow.

 

Ok, thanks for that. Yeah im still pretty new to all of this but i am learning. I have the tool on Firefox, that shows if the links are dofollow or not.
Im thinking now that people have to vote on my site in social bookmarking for it to count, so i will spend a bit more time bookmarking other peoples sites that look decent and hopefully they will return the favor.
Cheers.
