Hi,
I am doing work on Directory submission, blog and article commenting but i can’t found that it’s follow or do not follow. so please provide me any tools or method so that i can check it.
do you mean you want to check if a comment you post has nofollow links? it’s simple, just post a link then check the html code. if it contains rel=“nofollow” then it’s a nofollow (like the ones in this forum 
You can use firefox addons like search status, it will help you by highlighting the no follow links in the page. If it highlights the links in that page then it is a no follow site.
If you are using Firefox, there is a toolbar extension for firefox & Mozilla named Search Status, It has an option Highlight no follow links.
Hope this helps.
You should consider 3 cases:
- There may be a robots txt file which may prevent search engine to index the linking page (i. e. the page with your link).
- There may be a “no follow, no index” meta tag on the linking page.
- there may be an no-follow attribute with the link to your site .
So to be sure your link will be indexed, you should first check whether the page has a google cache or not, and then if there is no nofollow, as stated in previous answers.
Only one exception: a very new page may not have cache yet and get it a few days/weeks later on.
Do right click –> choose View Page Source –> a new window will display –> do/press ctrl f –> type nofollow.
If there is a nofollow word meaning the site has nofollow link.
If there is no nofollow word meaning the site has no nofollow link.
