but after Google penguin update it going down.
That means nothing at all, and tells you absolutely nothing about links that you
assume are a problem. 'Rankings' go up and down ALL the time and
YOU are probably the only one to see these results, so making alterations based on such ephemeral 'data' is NOT a good idea.
there are remark for webmaster if your website got affect after this update then you have to do Google Disavow link
And these remark
s are where?
Unless
YOU are responsible for the 'links'
AND you have received an "unnatural links" warning from Google you should NOT be 'disavowing' any of them.
The word 'disavow' means "to deny support for" or "deny responsibility for" in relation to or for something that you
were responsible for or did previously support. So you
should ONLY, 'disavow' links that
YOU did place or
knew they were being placed.
