If you have few number of pages you can remove it manually
one by one from Google webmaster but what if you have to remove hundred of
pages? There were many questioned raised on the google search forum that how we
can speed up the removal of pages from google’s search index.
Removing the pages one by one can be time consuming so what
you can do to speed up the process. Here is the solution provided by Google
webmaster trade analyst John Mueller.
How To Remove Pages From Google Search Index
Here is the answer from John Mueller. He said, “One way to
speed this up could be to submit a temporary sitemap file listing these URLs
with the last modification date (eg, when you changed them to 404 or added a
noindex), so that we know to recrawl & reprocess them,” he wrote in the
thread. “This is something you’d just want to do for a limited time (maybe a
few months), and then remove, so that you don’t end up in the long run with a
sitemap file that’s not needed by your site.”
Why it is important to remove pages
Well this is important from both prospective like suppose
you website got hacked and hacker created ton of pages and now you want to
remove that pages. Other reason is website authority. If there is lot of pages
on your site it can effect your website and domain authority.
How to create temporary sitemap?
While creating a temporary sitemap, there are certain things
which you need to keep in mind. First you 404 or set the pages to noindex. Then
you upload a temporary sitemap file with the URLs you want removed but make
sure to list them with the last modification date as of the date you set them
to 404. It can help speed things up by giving Google a hint to look at these
pages because they have changed. When they figure out the pages have changed
and are 404 error, Google may remove them faster.
