If it's < 1 year old, then I'd limit it to 15/day or 500 odd per month. Older domains it shouldn't matter so long as you can build them consistently.
Sorry, but that is not correct. Neither does the amount of backlinks one should build depend on the age of the domain, nor do you need to limit it to 15 links per day. Really, there is no limit!
Google sandbox effect. If a new site gets huge numbers of links overnight it raises a flag. One can build more links on a new site if one knows what one is doing, however if the OP knew what he was doing he wouldn't have had to ask the question...!
It depends on your time and goal but when your site is new and still growing, I would spend 1 hour a day or 8hrs a week on link building for 15 to 20 links a week and create the water cooler buzz for your site to get the snowball rolling.
Sorry, my bad MS - Market Samurai (it's a powerful SEO suite, just google for it and make use of their free trial) BLP - number of backlinks for a certain page (it's a value used in MS's seo competition module) BLD - number of backlinks for the domain (it's a value used in MS's seo competition module) Hope that helps!
Get as many links you can get! low quality link still helps! even not much but it still helps there won't be any quality link if there is no low quality link many low quality pointing to a page --> that page pointing to your site --> you get a quality link
Focusing on overall numbers of links is misguided. A single well-placed link on a key website is worth more than a whole year in which dozens of links a day are added to spammy or insignificant websites. The best links will always be from sites with strong editorial content who chose to link to your site because your site is the best resource on the web in some way or another. So if your site is not the best in some way, focus on getting it there before thinking of link building. When you have a top-notch site, you'll find that link building suddenly happens effortlessly...all you'll need to do is to do things that let people know about your site, and then people will be adding links left and right, on reputable sites with high traffic and high pagerank.
Is it usual to have 100 daily links on a fairly new website or it will be treated as signal for attention?
Don't worry about that Just think of a site that is new and releases some great new piece of content that everybody diggs, stumbles, blogs about etc...that site would get a huge influx of links over a really short period of time, even more than just 100 links per day, do you think Google would penalize the site with deindexing? No.
It depends on the quality of links. If you have good quality links, then you can get more backlinks otherwise you can't get.
You can have 100 links a day, you can post 10 articles a day to Isnare/Unique Article Wizard and you can double the amount per day...it all depends on many factors my friend. How old is your website? Is your website currently receiving links already on a daily basis, if so, how many on average? Is your website internally optimized to get results? Little questions, little details, big time long term traffic if done correctly from the beginning. It works knowing your details from the beginning. But overall, if your site is not new - e.g; 4-5 weeks old - you should not having problems getting 500 links a day or 5,000 links a day....just make sure you keep the same link creation consistency for not adding red flags at least from Google's end.
