What would you consider too much backlinking before search engines starting penalizing you? Afaik, say a young site under 6 months 50+ backlinks per month increasing by 40% per month would be too much...
Don't get wrapped up in numbers. Start out backlinking with a small number and gradually increase it.
Yeah i would agree to that gradually increase it and its better if they are coming from multiple sites not just a few.
I'd focus not so much on the number of backlinks you're picking up but the type of backlinks they are. Poor quality backlinks will be much more damaging than a large amount of natural-looking backlinks with some variety in the anchor text.
ive never heard of too many backlinks! Though I suppose if they all came overnight it would look artificial. You want to build them slowly over time, and its unlimited!
I've heard between 10 and 20 per day but this is something that we probably will never know nor does google want us to know.
You shouldn't get penalized for bad backlinks to your site since you don't have control on all of them. However, you do have control on your outbound links which could damage if they are bad links.
I dont see anything wrong with many backlinks. If too many backlinks means trouble, we can even sabotage the major websites.
