Hello, My website have a backlink with high pr that is 6 but with a single link my google webmaster showing 3000 backlinks, what should i do, disavow it or not?
do you mean you have a link to your site and that site is PR 6, but your Google Webmaster Tools is showing 3000 backlinks? Are those 3000 links coming from that same site? It could happen if the site is a blog and the link is on the sidebar, which means it appears on every single page of the site. You might wanna use Majestic or Moz to double check since GWT doesn't give you as good backlink profiles as those service that specialize in it.
Yeah, Totally agreed with you. If the link is in Footer or Sidebar then it gets multiplied and the number of backlinks may increase drastically depending upon the size of the linking website. I have seen 30K links coming from a single site in my GWT.
As long as the website is trusted enough and relevant traffic comes from it to your site, you are good.
Well if you wanna remove that links then first try to contact direct with that single site and remove it manually, if can't do this then use disavow links for this....
This type of issue usually occurs when the link is site wide based on Wordpress / blogspot blogs. I would suggest, authority or not, disavow the additional links leaving the link your originally acquired/made.
There are possibilities to receive a notification from Google for unnatural link building in these situations. Based on the relevancy and the type of back links you have acquired on the site, you have to make a decision on keeping the link or disavowing it.
If this is a Sidebar link, you do NOT have 1, but having 3k backlinks in total... But I won't disavowing it!!! If this is a plugin like Recent comments, your website would disappear in a matter of hours/days/weeks... Or to speed up the process write another few comments... (if this is the case of course!) If not, be sure to write a quick email to the webmaster and kindly ask him to remove your website from other pages!
