Google has launched a tool for disavowing specific links. Most of the webmasters affected by Google penguin update are going to use this tool to get rid of bad and low quality links. Now question raised by few SEOs is still they will have to adopt the process of link pruning or removal or they can just make a list of bad links and file it with Disavow Links Tool.
If you will listen to the video of Matt Cutts on Google Disavow Links you will find it has been said that First and foremost, he says and recommends getting those links actually removed from the web.
Now, at the same time we realize sometimes it’s not possible to get in contact with everybody – so – at the point were you’ve written to as many people as you can, multiple times, you really tried hard to get in touch and you’ve only been able to get – you know – some certain fractions of those links down and there’s still a small fraction of Links left, that’s where you can use our new tool, called the Disavow-Links-Tool.
Matt Cutts has clearly said that this tool to be used only for fractions of those links left which you have not been able to get removed via link removal process.
On Google webmaster Tool it is mentioned
If you’ve done as much as you can to remove the problematic links, and there are still some links you just can’t seem to get down, that’s a good time to visit our new Disavow links page.
As per above statement it is said that after doing all link pruning efforts if some links are left you can use the Disavow links tool
Google May not consider your Disavow links request
Matt Cutt said that Google reserves the right not to use the submissions if it feels there’s a reason not to trust them.
Same view are on blog
Google reserves the right to trust our own judgment for corner cases, for example—but we will typically use that indication from you when we assess links.
In Recent, Q&A With Google’s Matt Cutts, Cutts says try to remove links OR disavow requests might not get honored. Disavow link tool is not a replacement for making link removal requests. So you really need to go through link removals. Matt Says
I wouldn’t count on this. In particular, Google can look at the snapshot of links we saw when we took manual action. If we don’t see any links actually taken down off the web, then we can see that sites have been disavowing without trying to get the links taken down.
Disavow Tool will also look for actual removal of bad links or it will not work simply
Now what can be conclude from above statement if you try to file a raw file of links without giving any reason or doing any link removal efforts Google may reject your plea. Google want first to do your maximum bad link removing efforts and if nothing happen you can make use of Disavow Links
