How to safely exclude search result pages from Google's index?
-
Hello everyone,
I'm wondering what's the best way to prevent/block search result pages from being indexed by Google. The way search works on my site is that search form generates URLs like:
/index.php?blah-blah-search-results-blahI wanted to block everything of that sort, but how do I do it without blocking /index.php ?
Thanks in advance and have a great day everyone!

Hi Louise,
If you can ID the parameters, you can also look at blocking these in Webmaster Tools. This page explains more. As with any blocking of URLs, of course, proceed with caution.

I agree that can be effective. The reason I suggested the robots.txt is because Louise mentioned "blocking and preventing" as an objective. Robots.txt are particularly useful in the example where results from a search bar or something of that nature is involved. A NOINDEX, FOLLOW will not prevent bots from getting tired and dizzy, whereas the robots.txt can "block and prevent" bots from crawling certain parameters.
With all of that said, I think it is important to understand whether you need the bots to crawl and not index (in which case Spencer's answer is correct), or if you need to prevent bots from crawling the parameters altogether.
Hope that is more clear

I'm not sure that robots.txt is effective when url parameters are involved.
I would just add a meta robots tag to the head section of the search results template:

If you are able to identify a url parameter, you may excluded them using robots.txt. Here is a great resource on Robots.txt - http://moz.com/learn/seo/robotstxt

Does Google encryption of keyword data impact SEO revenue reporting in Google analytics?
Hi there, I know Google has been encrypting SEO keyword data which they rolled out in September 2013. My question is - will this impact SEO revenue figures reported in Google analytics? I have been monitoring SEO revenue figures for a client and they are significantly down even though rankings have not lowered. Is this because of Google's encryption? Could there be another reason? Many thanks!

Get a list of robots.txt blocked URL and tell Google to crawl and index it.
Some of my key pages got blocked by robots.txt file and I have made required changes in robots.txt file but how can I get the blocked URL's list. My webmaster page Health>blocked URL's shows only number not the blocked URL's.My first question is from where can I fetch these blocked URL's and how can I get them back in searches, One other interesting point I see is that blocked pages are still showing up in searches.Title is appearing fine but Description shows blocked by robots.txt file. I need urgent recommendation as I do not want to see drop in my traffic any more.

Google Analytics traffic hijacking?
Ran into something interesting a week ago - the same Google Analytics code was installed on two different sites by accident. The account was reporting traffic from both domains. Haven't found a definitive answer on how to stop this yet if it were to be used maliciously?

Will Google start trimming 'stale' sites rank?
With the recent focus on Google to reduce rank of farms and low value sites, I am interested to get SEO view on if you think Google will start devaluing stale sites. I do find it a bit frustrating that in the top 5 for my main key phrase, there is one site that has NO content just an error and another blog that has not updated content in 2 years. How can blogs that do not blog be considered high enough value by Google to rank in the top 5? How can sites that just return 404 or 500 for ALL their pages be even considered a site let alone rank 2nd. I am interested so see others experiences and thoughts on 'user experience' clean ups by Google and why these types of sites get missed?
