How to stop URLs that include query strings from being indexed by Google
-
Hello Mozzers
Would you use rel=canonical, robots.txt, or Google Webmaster Tools to stop the search engines indexing URLs that include query strings/parameters. Or perhaps a combination?
I guess it would be a good idea to stop the search engines crawling these URLs because the content they display will tend to be duplicate content and of low value to users.
I would be tempted to use a combination of canonicalization and robots.txt for every page I do not want crawled or indexed, yet perhaps Google Webmaster Tools is the best way to go / just as effective??? And I suppose some use meta robots tags too.
Does Google take a position on being blocked from web pages.
Thanks in advance, Luke

WIthout a specific example, there are a couple of options here. I am going to assume that you have an ecommerce site where parameters are being used for sort functions on search results or different options on a given product.
I know you may not be able to do this, but using parameters in this case is just a bad idea to start with. If you can (and I know this can be difficult) find a way to rework this so that your site functions without the use of parameters.
You could use canonicals, but then Google would still be crawling all those pages and then go through the process of using the canonical link to find out what page is canonical. That is a big waste of Google's time. Why waste Googlebots time on crawling a bunch of pages that you do not want to have crawled anyway? I would rather Googlebot focus on crawling your most important pages.
You can use the robots.txt file to stop Google from crawling sections of your site. The only issue with this is that if some of your pages with a bunch of parameters in them are ranking, once you tell Google to stop crawling it, you would then lose traffic.
It is not that Google does not "like" robot.txt to block them, or that they do not "like" the use of the canonical tag, it is just that there are directives that Google will follow in a certain way and so if not implemented correctly or in the wrong sequence can cause negative results because you have basically told Google to do something without fully understanding what will happen.
Here is what I would do. Long version for long term success
-
Look at Google Analytics (or other Analytics) and Moz tools and see what pages are ranking and sending you traffic. Make note of your results.
-
Think of the most simple way that you could organize your site that would be logical to your users and would allow Google to crawl every page you deem important. Creating a hierarchical sitemap is a good way to do this. How does this relate to what you found in #1.
-
Rework your URL structure to reflect what you found in #2 without using parameters. If you have to use parameters, then make sure Google can crawl your basic sitemap without using any of the parameters. Use robots.txt to then block the crawling of any parameters on your site. You have now ensured that Google can crawl and will rank pages without parameters and you are not hiding any important pages or page information on a page that uses parameters.
There are other reasons not to use parameters (e.g. easier for users remember, tend to be shorter, etc), so think about if you want to get rid of them.
- 301 redirect all your main traffic pages from the old URL structure to the new URL structure. Show 404s for all the old pages including the ones with parameters. That way all the good pages will move to the new URL structure and the bad ones will go away.
Now, if you are stuck using parameters. I would do a variant of the above. Still see if there are any important or well ranked pages that use parameters. Consider if there is a way to use the canonical on those pages to get Google to the right page to know what should rank. All the other pages I would use the noindex directive to get them out of the Google index, then later use robots to block Google crawling them. You want to do this in sequence as if you block Google first, it will never see the noindex directive.
Now, everything I said above is generally "correct" but depending on your situation, things may need to be tweaked. I hope the information I gave might help with you being able to work out the best options for what works for your site and your customers.
Good luck!

Google indexed "Lorem Ipsum" content on an unfinished website
Hi guys. So I recently created a new WordPress site and started developing the homepage. I completely forgot to disallow robots to prevent Google from indexing it and the homepage of my site got quickly indexed with all the Lorem ipsum and some plagiarized content from sites of my competitors. What do I do now? I’m afraid that this might spoil my SEO strategy and devalue my site in the eyes of Google from the very beginning. Should I ask Google to remove the homepage using the removal tool in Google Webmaster Tools and ask it to recrawl the page after adding the unique content? Thank you so much for your replies.

Google does not want to index my page
I have a site that is hundreds of page indexed on Google. But there is a page that I put in the footer section that Google seems does not like and are not indexing that page. I've tried submitting it to their index through google webmaster and it will appear on Google index but then after a few days it's gone again. Before that page had canonical meta to another page, but it is removed now.

Will disallowing URL's in the robots.txt file stop those URL's being indexed by Google
I found a lot of duplicate title tags showing in Google Webmaster Tools. When I visited the URL's that these duplicates belonged to, I found that they were just images from a gallery that we didn't particularly want Google to index. There is no benefit to the end user in these image pages being indexed in Google. Our developer has told us that these urls are created by a module and are not "real" pages in the CMS. They would like to add the following to our robots.txt file Disallow: /catalog/product/gallery/ QUESTION: If the these pages are already indexed by Google, will this adjustment to the robots.txt file help to remove the pages from the index? We don't want these pages to be found.

Best practice for removing indexed internal search pages from Google?
Hi Mozzers I know that it’s best practice to block Google from indexing internal search pages, but what’s best practice when “the damage is done”? I have a project where a substantial part of our visitors and income lands on an internal search page, because Google has indexed them (about 3 %). I would like to block Google from indexing the search pages via the meta noindex,follow tag because: Google Guidelines: “Use robots.txt to prevent crawling of search results pages or other auto-generated pages that don't add much value for users coming from search engines.” http://support.google.com/webmasters/bin/answer.py?hl=en&answer=35769 Bad user experience The search pages are (probably) stealing rankings from our real landing pages Webmaster Notification: “Googlebot found an extremely high number of URLs on your site” with links to our internal search results I want to use the meta tag to keep the link juice flowing. Do you recommend using the robots.txt instead? If yes, why? Should we just go dark on the internal search pages, or how shall we proceed with blocking them? I’m looking forward to your answer! Edit: Google have currently indexed several million of our internal search pages.

Google Said "Repeat the search with the omitted results included."
We have some pages targeting the different countries but with the Near to Similar content/products, just distinguished with the country name etc. one of the page was assigned to me for optimizing. two or three Similar pages are ranked with in top 50 for the main keyword. I updated some on page content to make it more distinguish from others. After some link building, I found that this page still not showing in Google result, even I found the following message on the google. "In order to show you the most relevant results, we have omitted some entries very similar to the 698 already displayed.

If you like, you can repeat the search with the omitted results included." I clicked to repeat omitted result and found that my targeted url on 450th place in google (before link building this was not) My questions are Is google consider this page low quality or duplicate content? Is there any role of internal linking to give importance a page on other (when they are near to similar)? Like these pages can hurt the whole site rankings? How to handle this issue?0 -
Should I prevent Google from indexing blog tag and category pages?
I am working on a website that has a regularly updated Wordpress blog and am unsure whether or not the category and tag pages should be indexable. The blog posts are often outranked by the tag and category pages and they are ultimately leaving me with a duplicate content issue. With this in mind, I assumed that the best thing to do would be to remove the tag and category pages from the index, but after speaking to someone else about the issue, I am no longer sure. I have tried researching online, but there isn't anything that provided any further information. Please can anyone with any experience of dealing with issues like this or with any knowledge of the topic help me to resolve this annoying issue. Any input will be greatly appreciated. Thanks Paul
