I think there is no limit of creating good and quality backlinks each day, as many as you can for ranking high in search result of a search engine.
The first week aim for 10-20 / day. Try for a combination of article directories / web 2.0 sites (hubpages / squidoo / wordpress) / forum posts / social bookmarks. Then try to INCREASE your links / day with 10-20% / week. This is called link velocity. You need to accelerate your link building so Google sees your site with better eyes! "WOW, more and more sites link to this site! We'll get it on 1st page of our search engine asap". Link velocity / link popularity / link diversity / link relevancy. Google each of these terms and read everything. Also check SEOmoz for their SEO articles + subscribe to a few seo gurus' RSS feeds using FEED READER. That's the best advice i can give you right now. Now go back to work and start building those links!
You can get how many links do you want. Do you know how many sites are listed in Google? Do you think that G can every day watch at them and at their backlinks? And how G can say if these links are natural or not to give penalizations? Don't worry about the number.
I feel along with quality the number of backlinks is also more important. It can be from sites belonging to different subjects, having different pr. That would look natural also.
Just keep the links coming in regularly and from a variety of sources. Don't build thousands of backlinks one day and then nothing for weeks, SY
There is no set limit. It depends on your site. If it's new, then a large number of backlinks will look unnatural and suspicious. If your site is already established, then any number should be fine as long as you increase the number of backlinks per day gradually.
If it's a new site, you can start adding a few hundred within a couple of weeks, after that you can add a lot more. I've only heard of penalties for new sites that suddenly add 1,000+ links.
I just wrote a blog post about this.. http://www.alex-brooks.com/link-building/how-many-links-should-i-build-per-month-answered/
I think it won't cause any problem. If your site is rather popular, it is getting tons of back links per day
Oh, and it also depends on how much content you have on your site. If Google sees that you have only a few pages and zillions of links pointing to them, it might get suspicious, SY
Well to increase backlinks per day than you have to utilize those resources that are of high rank and beneficial for your site ranking.use blog commenting, forum posting to get high quality and increase number of links to your site.
I'm currently very active in 3 forums, doing about 20 posts on each forum everyday, each post has a signature with 3 backlinks to 3 different pages within my site That's 180 backlinks a day. I know that to many people 180 backlinks is nothing, but I just wanted to say that google isn't penalizing me at all, instead it has helped my SERP alot!
I think if the domain is new and you get / buy many links from higher ranked domains, your domain goes to sandbox. am I wrong ?
