      Hi,

      Google has indexed a few .CSS and .JS files that belong to our WordPress plugins and themes. I had them blocked via robots, but realized this doesn't prevent indexation (and can likely hurt us since Google wants to access these files).

      I've since removed the robots instructions, submitted a removal request via Search Console, but want to make sure they don't come back.

      Is there a way to put a noindex tag within .CSS and .JS files? Or should I do something with .htaccess instead?

        I figured .htaccess would be the best route. Thank you for researching and confirming. I appreciate it.

          Hi Tim,

          Assigning a noindex tag to these files will not block them, only prevent them from showing in SERPs. This is the intended goal and the reason I deleted my robots.txt file which prevented crawling.

            There's quite a big difference between crawling directives, which block and indexing directives. This article by (former?) Moz user S_ebastian_ is a good foundation read.

            This article at developers.google.com is a good second read. If I'm understanding it right, Google thinks in terms of crawling directives vs indexing / serving directives.

            My attempt at <tl rl="">:</tl>

            crawling = looking, using in any way :: controlled via robots.txt

            indexing / serving = indexing, archiving, displaying snippets in results, etc :: controlled via html meta tags or web server htaccess (or similar for other web servers).

            I'm not convinced yet, that asking for noindex via htaccess causes the same sort of grief that deny in robots.txt causes.

              I would seriously think again when it comes to blocking/no-indexing your CSS and JS files - Google has in the past stated that if they cannot fully render your site properly then this could lead to poorer rankings.

              You will also likely get notifications in your Search Console as errors for this too.

              Check out this great article from July this year which goes into more details.

                I haven't encountered undesirable .css or .js indexing myself (yet), but as you surmised, maybe this htaccess directive might be worth trying?

                <filesmatch ".(txt|log|xml|css|js)$"="">Header set X-Robots-Tag "noindex"</filesmatch>

                Google seems to support it

                  Unless I'm severely misreading the links provided, which I've read before, it seems Google is stating that they read, render, and sometimes index .CSS and .JS files. Here's an article written a week after the second article you posted.

                  The aforementioned WordPress plugin and theme files hosted on my server are indeed showing up in Google SERPs.

                  I do not want to prevent Googlebot from reaching these files as they're needed for optimal site performance, but I do want them to be no-indexed. Thus, I don't want robots.txt to prevent crawling, only indexing.

                  Let me know if I'm misunderstanding.

                    TL;DR - You're hesitated about problem that doesn't exist.

                    Googlebot doesn't index CSS or JS files. They index text files, HTML, PDF, DOC, XLS, etc. But doesn't index style sheets or javascript files.

                    All you need in WordPress is to create blank robots.txt file where WP is installed with this content:

                    User-agent: *
                    Disallow:
                    Sitemap: http://site/sitemap-file-name.xml

                    And that's all. This is explain many times:

                      Page Indexing without content

                      indexing seo

                      Hello. I have a problem of page indexing without content. I have website in 3 different languages and 2 of the pages are indexing just fine, but one language page (the most important one) is indexing without content. When searching using site: page comes up, but when searching unique keywords for which I should rank 100% nothing comes up. This page was indexing just fine and the problem arose couple of days ago after google update finished. Looking further, the problem is language related and every page in the given language that is newly indexed has this problem, while pages that were last crawled around one week ago are just fine. Has anyone ran into this type of problem?

                      Keywords are indexed on the home page

                      indexation keyword rankings

                      Hello everyone, For one of our websites, we have optimized for many keywords. However, it seems that every keyword is indexed on the home page, and thus not ranked properly. This occurs only on one of our many websites. I am wondering if anyone knows the cause of this issue, and how to solve it. Thank you.

                      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!

                      Not all images indexed in Google

                      Hi all, Recently, got an unusual issue with images in Google index. We have more than 1,500 images in our sitemap, but according to Search Console only 273 of those are indexed. If I check Google image search directly, I find more images in index, but still not all of them. For example this post has 28 images and only 17 are indexed in Google image. This is happening to other posts as well. Checked all possible reasons (missing alt, image as background, file size, fetch and render in Search Console), but none of these are relevant in our case. So, everything looks fine, but not all images are in index. Any ideas on this issue? Your feedback is much appreciated, thanks

                      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.

                      How to Remove /feed URLs from Google's Index

                      Hey everyone, I have an issue with RSS /feed URLs being indexed by Google for some of our Wordpress sites. Have a look at this Google query, and click to show omitted search results. You'll see we have 500+ /feed URLs indexed by Google, for our many category pages/etc. Here is one of the example URLs: http://www.howdesign.com/design-creativity/fonts-typography/letterforms/attachment/gilhelveticatrade/feed/. Based on this content/code of the XML page, it looks like Wordpress is generating these: <generator>http://wordpress.org/?v=3.5.2</generator> Any idea how to get them out of Google's index without 301 redirecting them? We need the Wordpress-generated RSS feeds to work for various uses. My first two thoughts are trying to work with our Development team to see if we can get a "noindex" meta robots tag on the pages, by they are dynamically-generated pages...so I'm not sure if that will be possible. Or, perhaps we can add a "feed" paramater to GWT "URL Parameters" section...but I don't want to limit Google from crawling these again...I figure I need Google to crawl them and see some code that says to get the pages out of their index...and THEN not crawl the pages anymore. I don't think the "Remove URL" feature in GWT will work, since that tool only removes URLs from the search results, not the actual Google index. FWIW, this site is using the Yoast plugin. We set every page type to "noindex" except for the homepage, Posts, Pages and Categories. We have other sites on Yoast that do not have any /feed URLs indexed by Google at all. Side note, the /robots.txt file was previously blocking crawling of the /feed URLs on this site, which is why you'll see that note in the Google SERPs when you click on the query link given in the first paragraph.

                      Iframes & SEO

                      I've got a client that wants a site with all content in iFrames. They saw another site they liked & asked if we could do it.  Of course we can technically.  How big a negative hit would they take with SEO?  Is there anything we can do to mitigate it, such as redirects, etc? Thanks for the help!
