text link checker tool

Guys today I found some helpful sites which will be fruitful for every blog owner.In my email there was a news letter about this text link checker tools along with some more site information which are too important.
               I just visited them and found very interesting and thinks to write about it.Firstly I visit the site which will tell you about your site's link status.I put there my link to check,they scan present me a full details.The report was about my spam link,redirect link,the site which are associated with sex,gambling etc.I think I could be more alert about those site link which are vulnerable for me.

Secondly I found another link which was about your domain indexing status.this will tell you how many page of your site has indexed by search engine like Google,Yahoo,Bing etc.

And ob course the third site was about free submitting of article,this is too important for any blogger.i think anybody will have tendency to get some exposure from their content/topics freely.
Thanks.
