Link Building - What's To Much?

I would LOVE to know the answer to this as well!

You should vary the number of links you get daily: one day 10, another day 7, 12 and so on.

Also don't forget that domain diversity is extremely important. If you're getting all your links from the same domains, unless you're optimizing for the long tail, you're wasting your time.

Lastly, the most important thing is the quality of the links. A good PR7 link can outperform hundreds of PR3. Many of the links you're getting won't even be PR2. Be creative in order to get higher value links...

Any suggestions on how build quality back links for the blog in my sig 'cos all my work on it seems not to be noticed.

There are a number of variables if you are looking at what is acceptable linking and also what kind of links are more important than others. You haven't said where you're getting the links for example. Assuming you are getting anchor text backlinks that you are targeting then these are usually more important than getting backlinks from high PR sites that are irrelevant to your site's content. For example, how many people are spamming blogs for comments (even when they are not nofollow links) and leaving their name as the anchor text. Absolutely useless in my opinion. Articles, squidoo lenses, hubpages, etc etc - these can give you good anchor text backlinks because you can control the content and placement to make sure it's relevant and utilizing your keywords. That's the key to successful backlinking for starters. As for how many... seeing your site is 3 months old and assuming you've been regularly updating the content, you should be able to go hell for leather getting backlinks as fast as you like and as Nossie rightly said, Google isn't going to see the links coming all at once, particularly if you are getting 3rd party links and not creating link farms (which takes a different tack).

Damn. A week ago I hired an outsourcer to build some high ranking links with my keywords. He did it really quickly (80 links in a few days). I was ranked #5 for one of my top terms, now I'm nowhere on the first 5 pages.... hmmmm sh*t!
