I'm just wondering how much is the ideal backlinks amount to make per day? That will not make harm to your sites and Google will see it natural.
If you're wondering how many link farmers are doing and getting caught, [cough]JCPenny]/cough], I would suspect it to be a very high amount. Unless you're trying to do thousands a day, you'll be fine.
The answer to this would depend upon a couple of things. First of all, how old is your site? If you site is older and established you can build more links than a new site. Also, as SeoDezin said, you want to be consistent. So my question would be, how many links are you willing to build on a regular basis? Building a thousand links today and then none for a month doesn't look at all natural. So choose an amount that you are prepared to build again next week and the week after....etc.
If you are getting links manually, I really don't think there is a maximum amount... if automated, it depends on your site like jody_w said.
Haha, I loved the JCPenney comment. But seriously, just remember quality back links are better than quantity.
On a new site, you risk getting sandboxed if you rely on a large amount of low quality links as opposed to a smaller amount of high quality links. A ton of high quality links is good too of course. There's really no rule for how many per day or anything like that. Most sites that gain links naturally won't have a steady pattern, they'll come more in bursts.
there is no limit for back links. you can post as many links as you can via blog posting article directory etc and in turn you can enjoy healthy traffic
It totally depends on you, no limit of back-links. If you can generate 30 back-links each day good but should be continuously. If you can only make 10 back-links manually, keep it 10 daily. I want to say make a target for back-links each day and continue regularly.
