I am not sure how to check for a no follow link but I am pretty sure you just right click on the link then go to properties and it shows the attribute? I am just asking because I think one forum I go to provides signature links but it is no follow.
I go to page->view source of the browser, than Search and type "nofollow" in the search box. If it finds something usually all links are with this attribute.
It is possible to put the "nofollow" atribute in external css settings? Because, in this case, you can't simply verify the html source of the page.
What do you mean external CSS? Actually you can verify the HTML Source. Just right click on the page and click View Page Source.. Not sure what else you mean by that.
No, you can use it: 1. for particular links 2. for whole page in meta tags 3. for whole site (or not) in robots.txt
you can look the source goes . this is easiest way. i also suggest http://oy-oy.eu/page/links/ . it's a good tool to check the links on a page
We can customize the links that robots (crawl) should follow.In most of the scripts we use in inorder to keep robot away from our restricted areas. Hackers make use of this if u allow robots to crawl all the place of ur site !
