I want to put 65.000 productpages on NOINDEX, FOLLW at once! Would Google mind?

[Zanox]

Or have we do this step by step, i.e:

13.000 pages on noindex
13.000 pages on noindex
13.000 pages on noindex
13.000 pages on noindex
13.000 pages on noindex

Makes together: 65.000 pages

I think you would be fine doing it all at once. The gradual roll-out thing Matt Cutts was referring to had to do with adding pages, not removing them.

You could also use the URL removal tool to get them taken out of the index faster once you have added the noindex,follow tag. You can remove an entire directory that way in one fell swoop as long as you don't need any other pages in that directory to be indexed either.

This is a smart move for a lot of eCommerce sites that like to drop ship products and use manufacturer or distributor-supplied product descriptions at a level that is not scaleable for rewriting on their own. In such cases I optimize the best performing products, get the rest out of the index, and rely heavily on category pages for bringing in search traffic. It isn't the best situation, but it's better than keeping a Panda penalty.

Always keep in mind that Google will not simply re-crawl all those pages right away.

It can take weeks/months for Google to crawl each page and change its indexing.

I have personally done this for over 1.5 million pages all in one go on my site and had no issues.

Staggering it will not help control the speed at which googlebot looks at them.

That's should be fine. I am glad you said noindex,Follow and not noindex,nofollow.
Remus presents a link by matt cuts, but that is talking about adding pages in great numbers

Hi Wesley,

It's better if you do it in stages. A more gradual roll out is also recommended by Matt Cutts. His example is for 200K pages, but 65K is not so far away. I think the approach should be the same.

Check his video, it will help you understand what's better:

Should I add an archive of hundreds of thousands of pages all at once?

I hope this helps, good luck!
