If you are getting good back links its good. But if you are building more links within 1 or 2 days it may affect ranking IMO
Too much everything is not good. Build quality backlinks that will become helpful to your site,not quantity.
If you build too many links too quickly, google may view your building efforts as spam and this will impact upon your ranking for a time.
It can improve your rankings but there is also tendencies that will can also have an bad effect to a site. Just remember that when you decided to build lot of backlinks you must be consistent in doing it because if don't Google will see that as suspicious. It might decrease your rankings.
That is correct. Just keep building links, I think it's a myth that a lot of links could hurt your website - but I would like to be on the safe side. lol
if you build 1000 links per day then it definately will hurt your site However, it will be fine to build 20 link per day
You can never have too many incoming links to your website if you do so the proper, manual way. If you start to use machines Google and other search engines might catch on and ban your site :S. As long as you stick to promoting and marketing your website by practical and honest ways, you will show an increase in traffic and SER .
in short period of time ur site gain too much backlink or our site is new then there is some negative effect on your site SERP Result.
