I am running a forum. From the start i started to get some good backlinks from do-follow blogs, forums, etc., Within 3 weeks my forum got PR3. My forum is going good. But i heard that google will penalize the sites which makes lots of backlinks daily. Really google will penalize the sites which gets lots of backlinks daily ?????
Unless you are buying or trading links in an unrelated niche you should be fine. I would also make sure the blogs you are commenting on are not spam blogs. The comments you leave may appear to be left from a spammer, not because you are on, but because the blog has had previous spam comments. Also, you won't really have any troubles unless you are adding over 1,000 backlinks a day in a short space of time.
ok, thanks, i only make small amount of backlinks, but i will make the google to index the page where i made backlink.
I would not worry about it either. It is not likely that anything will happen unless you get an outrageous amount of backlinks in one day.
You need to make sure you do not cross the threshold of suspicous link bursts. This is calculated by Google based on each individual site...history, link gain and loss over time, etc.
No you will not get penalized. It would have to be a pretty extreme number of backlinks acquired per day for your site to raise a flag with Google.
If you start to spam all over internet, not taking care about the quality of backlinks, you can be filtered or penalized in another, sophisticated way.
Just keep on building those back links, don't worry about Google penalizing you because I'm sure that you can't build a thousand back links on a single day.
Unless you are accumulating links at an ungodly rate I don't think that Google will penalize you. It would take something pretty egregious for Google to flag a site as bad.
