Yes, those are some good links. Looks like you've been busy! How much traffic are you receiving monthly?
Are you sure that those links are dofollow? Looks good, but a little bit strange, how is it possible to have 2k+ backlinks from a site like scoop.it ... Good luck with your website!
The easiest way to check your bad links and your competitor's good links. you can check your back links in good links and bad links. I suggest, you can use this site monitorbacklinks dot com and check it so bad link and good link.
Links are good but from scoop you got 20718 links I don't think its good way to build your back links. Always remember if you got one link from yahoo then google boost your ranking 15% or if you got 15 links from yahoo then result ll same your ranking ll be boost 15%, coz of you are getting all the links from same IP address
How well are your keywords ranking on SERP's? Even having few hundred thousands links and still not ranking well in SERP's wouldn't make any difference. I was working on a case study and found a website having only 33 backlink, still the website had PR3 and site was ranking well in SERP's with majority of keywords in 1-3 page. Which one would you choose, number of backlinks or organic rankings?
The number is good but it seems that they are mostly from comments on free blogs and social bookmarking sites. The links are good but all of them are coming from several domains, and they are probably on low ranking pages. To improve your search engine rankings you need real links coming from authority sites and pages. By authority I mean established websites with good trust on search engines. Tumblr, Wordpress or Scoop are authority sites, but they have hundreds of millions of pages and if you have 2000 links on a site with 10 million pages then they are not that important. You need links posted on pages that already rank well in search engines. For example, link inside a popular blog post. Coment links are devalued heavily by Google. You need the link to be in-content or somewhere else.
