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 Site A's Content On Site B, Site C etc
Hi All, I have an issue where the content (pages and images) of Site A (www.ericreynolds.photography) are showing up in Google under different domains Site B (www.fastphonerepair.com), Site C (www.quarryhillvet.com), Site D (www.spacasey.com). I believe this happened because I installed an SSL cert on Site A but didn't have the default SSL domain set on the server. You were able to access Site B and any page from Site A and it would pull up properly. I have since fixed that SSL issue and am now doing a 301 redirect from Sites B, C and D to Site A for anything https since Sites B, C, D are not using an SSL cert. My question is, how can I trigger google to re-index all of the sites to remove the wrong listings in the index. I have a screen shot attached so you can see the issue clearer. I have resubmitted my site map but I'm not seeing much of a change in the index for my site. Any help on what I could do would be great. Thanks

Https & http urls in Google Index
Hi everyone, this question is a two parter: I am now working for a large website - over 500k monthly organic traffic. The site currently has both http and https urls in Google's index. The website has not formally converted to https. The https began with an error and has evolved unchecked over time. Both versions of the site (http & https) are registered in webmaster tools so I can clearly track and see that as time passes http indexation is decreasing and https has been increasing. The ratio is at about 3:1 in favor of https at this time. Traffic over the last year has slowly dipped, however, over the last two months there has been a steady decline in overall visits registered through analytics. No single page appears to be the culprit, this decline is occurring across most pages of the website, pages which traditionally draw heavy traffic - including the home page. Considering that Google is giving priority to https pages, could it be possible that the split is having a negative impact on traffic as rankings sway? Additionally, mobile activity for the site has steadily increased both from a traffic and a conversion standpoint. However that traffic has also dipped significantly over the last two months. Looking at Google's mobile usability error's page I see a significant number of errors (over 1k). I know Google has been testing and changing mobile ranking factors, is it safe to posit that this could be having an impact on mobile traffic? The traffic declines are 9-10% MOM. Thank you. ~Geo

Google don't index .ee version of a website
Hello, We have a problem with our clients website .ee. This website was developed by another company and now we don't know what is wrong with it. If i do a Google search "site:.ee" it only finds konelux.ee homepage and nothing else. Also homepage title tag and meta dec is in Finnish language not in Estonian language. If i look at .ee/robots.txt it looks like robots.txt don't block Google access. Any ideas what can be wrong here? BR, T

Should we use URL parameters or plain URL's=
Hi, Me and the development team are having a heated discussion about one of the more important thing in life, i.e. URL structures on our site. Let's say we are creating a AirBNB clone, and we want to be found when people search for apartments new york. As we have both have houses and apartments in all cities in the U.S it would make sense for our url to at least include these, so clone.com/Appartments/New-York but the user are also able to filter on price and size. This isn't really relevant for google, and we all agree on clone.com/Apartments/New-York should be canonical for all apartment/New York searches. But how should the url look like for people having a price for max 300$ and 100 sqft? clone.com/Apartments/New-York?price=30&size=100 or (We are using Node.js so no problem) clone.com/Apartments/New-York/Price/30/Size/100 The developers hate url parameters with a vengeance, and think the last version is the preferable one and most user readable, and says that as long we use canonical on everything to clone.com/Apartments/New-York it won't matter for god old google. I think the url parameters are the way to go for two reasons. One is that google might by themselves figure out that the price parameter doesn't matter (https://support.google.com/webmasters/answer/1235687?hl=en) and also it is possible in webmaster tools to actually tell google that you shouldn't worry about a parameter. We have agreed to disagree on this point, and let the wisdom of Moz decide what we ought to do. What do you all think?

URL errors in Google Webmaster Tool
Hi Within Google Webmaster Tool 'Crawl errors' report by clicking 'Not found' it shows 404 errors its found. By clicking any column headings and it will reorder them. One column is 'Priority' - do you think Google is telling me its ranked the errors in priority of needing a fix? There is no reference to this in the Webmaster tool help. Many thanks Nigel

Google Re-Index or multiple 301 Redirects on the server?
Over a year ago we moved a site from Blogspot that was adding dates in the URL's (i.e.. blog/2012/08/10/) Additionally we've removed category folders (/category, /tag, etc). Overall if I add all these redirects (from the multiple date options, etc) I'm concerned it might be an overload on the server? After talking with the server team they had suggested using something like 'BWP Google Sitemaps' on our Wordpress site, which would allow Google some time to re-index our site. What do you suggest we do?
