      I have a strange situation on a website, when I do a Google query of site:example.com all the top indexed results appear to be queries that users can perform on the website. So any random term the user searches for on the website for some reason is causing the search result page to get indexed - like example.com/search/query/random-keywords

      However, the search results page has a canonical tag on it that points to example.com/search, but that doesn't seem to be doing anything. Any thoughts or ideas why this could be happening?

        Hi there,

        First of all, its a mistake to think that when searching with _site:  _operator, the first results are the most important nor the more relevant. Google has said a few times that we shouldn't rely that much on what that search in terms of what's being shown.

        Blocking search results with robots.txt wont be of help, as it will not remove already indexed pages and cant prevent for new pages to be indexed (if there's an external link to a robots.txt blocked page, google can still index it) it'll only prevent Googlebot from discovering new ones FROM YOUR SITE.

        Again, i'd try to dig deeper to understand where are the links to internal searches that google is finding. Googlebot will not do any search in your site.

        The thing with GSC, might be related to quite a few reasons. I cant say much because I don't know any more specifics, but from what you are telling me it looks like you are getting impressions in searches that you don't relate to your site and that land on pages that google is noindexing. Yeah im repeating the obvious, hehe. 
        In my experience, Google can have these strange behaviours. You know, there are cases when a page is canonicalized, but it can still be shown in SERPS. Dont ask me why, but it happens. It takes a little time to google fully replace it with the correct one.
        I'd wait a little longer to see how Google is handling them.

        I don't know if im helping you. 
        it kinda took me a few minutes to understand/process what you wrote and come up with an answer.

        Please, feel free ask again or comment on my reply if I misunderstood something.

        Best luck,
        Gaston

          Hi here's some more background info on this situation that makes it even stranger. I can perform some pretty specific searches on Google where these indexed search result pages show up. And I can look in Google Search Console under the performance section and see that those pages receive impressions and clicks. However, if I inspect the URL, Search Console says it is not included in Google's index, and the reason it gives under indexing is because it says it is honoring the canonical URL. So search console is saying it isn't indexed because of the canonical, but I can do searches and find that exact URL in the index. Any ideas what this could be from?

            Hi Gaston,

            Thanks for the response. I can confirm that the example, /search and /search?q=foo are pretty much identical. However that may not always be the case, only when a user searches for something that would return no results. So, a website that sells widgets, /search and /search?q=widgets would not be identical, and in that case it would make sense that Google would not honor the canonical link. What's really strange is if I search google for the site: operator of the domain, the top pages are not user queries for things that make sense. The top indexed pages are random, non-relevant user searches.

            I do not have a way with this system to control noindex tags on these search result pages. The only thing I could do is take the nuclear option and just block it all with robots.txt using wildcards. But that means no search result pages would get indexed, relevant or not.

              Hi there,

              in my experience, when google doesn't honor Canonicals, is because pages arent similar.
              In its definition, canonical are there for two or more pages that have the same content.

              If you are finding it problematic, i'd suggest to use noindex tags for that search pages.
              I'd investigate If there are links pointing to those internal search pages, as its not common for google to discover search pages.

              Hope it helps,
              Best luck.

                Google is indexing bad URLS

                Hi All, The site I am working on is built on Wordpress. The plugin Revolution Slider was downloaded. While no longer utilized, it still remained on the site for some time. This plugin began creating hundreds of URLs containing nothing but code on the page. I noticed these URLs were being indexed by Google. The URLs follow the structure: www.mysite.com/wp-content/uploads/revslider/templates/this-part-changes/ I have done the following to prevent these URLs from being created & indexed: 1. Added a directive in my Htaccess to 404 all of these URLs 2. Blocked /wp-content/uploads/revslider/ in my robots.txt 3. Manually de-inedex each URL using the GSC tool 4. Deleted the plugin However, new URLs still appear in Google's index, despite being blocked by robots.txt and resolving to a 404. Can anyone suggest any next steps? I Thanks!

                Folders in url structure?

                Hello, Revamping an out-of-date website and am wondering if I need to include the folders (categories) in the url structure? The proposed structure has 8 main folders. I've been reading that Google is ok if the folder is not included in the url, but is it really? The hesitation I have is that the urls are getting long and the main folder only has only a sub folder beneath it. So, /folder-name/facility-name/treatment-overview. This looks too long, doesn't it? Thanks!

                Category URL Pagination where URLs don't change between pages

                Hello, I am working on an e-commerce site where there are categories with multiple pages. In order to avoid pagination issues I was thinking of using rel=next and rel=prev and cannonical tags. I noticed a site where the URL doesn't change between pages, so whether you're on page 1,2, or 3 of the same category, the URL doesn't change. Would this be a cleaner way of dealing with pagination?

                301 redirect: canonical or non canonical?

                Hi, Newbie alert! I need to set up 301 redirects for changed URLs on a database driven site that is to be redeveloped shortly. The current site uses canonical header tags. The new site will also use canonical tags. Should the 301 redirects map the canonical URL on the old site to the corresponding canonical for the new design . . . or should they map the non canonical database URLs old and new? Given that the purpose of canonicals is to indicate our preferred URL, then my guess is that's what I should use. However, how can I be sure that Google (for example) has indexed the canonical in every case? Thx in anticipation.

                Why is Google replacing our title tags with URLs in SERP?

                Hey guys, We've noticed that Google is replacing a lot of our title tags with URLs in SERP. As far as we know, this has been happening for the last month or so and we can't seem to figure out why. I've attached a screenshot for your reference. What we know: depending on the search query, the title tag may or may not be replaced. this doesn't seem to have any connection to the relevance of the title tag vs the url. results are persistent on desktop and mobile. the length of the title tag doesn't seem to correlate with the replacement. the replacement is happening at mass, to dozens of pages. Any ideas as to why this may be happening? Thanks in advance,

                Using the Google Remove URL Tool to remove https pages

                I have found a way to get a list of 'some' of my 180,000+ garbage URLs now, and I'm going through the tedious task of using the URL removal tool to put them in one at a time. Between that and my robots.txt file and the URL Parameters, I'm hoping to see some change each week. I have noticed when I put URL's starting with https:// in to the removal tool, it adds the http:// main URL at the front. For example, I add to the removal tool:- https://www.mydomain.com/blah.html?search_garbage_url_addition On the confirmation page, the URL actually shows as:- http://www.mydomain.com/https://www.mydomain.com/blah.html?search_garbage_url_addition I don't want to accidentally remove my main URL or cause problems. Is this the right way this should look? AND PART 2 OF MY QUESTION If you see the search description in Google for a page you want removed that says the following in the SERP results, should I still go to the trouble of putting in the removal request? www.domain.com/url.html?xsearch_... A description for this result is not available because of this site's robots.txt – learn more.

                Old URL redirect to New URL

                Alright I did something dumb a year a go and I'm still paying for it. I changed my hyphenated URL to the non-hyphenated version when I redesigned my website. I say it was dumb because I lost most of my link juice even though I did 301 redirects (via the htaccess file) for almost all of the pages I could find in Google's index. Here's my problem. My new site took a huge hit in traffic (down 60%) when I made the change and even though I've done thousands of redirects my old site is still showing up in the SERPS and send much if not most of my traffic. I don't want to take the old site down in fear it will kill all of my traffic. What should I do? Is there a better method I should explore then 301 redirects? Could the other site be affecting my current rank since it's still there? (FYI...both sites are built on the WP platform). Any help or ideas are greatly appreciated. Thank you! Joe

                URL query strings and canonical tag

                Hi, I have recently been getting my comparison website redesigned and developed onto wordpress and the site is now 90% complete. Part of the redesign has meant that there are now dynamic urls in the format: http://www.mywebsite.com/10-pounds-productss/?display=cost&value=10 I have other pages similar to this but with different content for the different price ranges and these are linked to from the menus: http://www.mywebsite.com/20-pounds-products/?display=cost&value=20 Now my questions are: 1. I am using Joost's All-in-one SEO plugin and this adds a canonical tag to the page that is pointing to http://www.mywebsite.com/10-pounds-products/ which is the permalink. Is this OK as it is or should i change this to http://www.mywebsite.com/10-pounds-products/?display=cost&value=10 2. Which URL will get indexed, what gets shown as the display URL in the SERPs and what page will users land on? I'm a bit confused so apologies if these seem like silly questions. Thanks
