      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:

                      Discovered - currently not indexed issue

                      Hello all, We have a sitemap with URLs that have mostly user generated content. Profile Overview section. Where users write about their services and some other things. Out of 46K URLs, only 14K are valid according to search console and 32K URLs are excluded. Out of these 32K, 28K are "Discovered - currently not indexed". We can't really update these pages as they have user generated content. However we do want to leverage all these pages to help us in our SEO. So the question is how do we make all of these pages indexable? If anyone can help in the regard, please let me know. 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

                      Indexing product attributes in sitemap

                      Hey Mozzers! I'm battling a few questions about the sitemap for my ecommerce store. Could you help me out? Is it necessary to include your product attributes in the sitemap? I'm not sure why it would matter to have a sitemap that lists everything in the color cherry. Also, if the attributes were included in the sitemap, would that count as duplicate content for the same products to show up in multiple attributes? Is there any benefit to submitting the sitemaps individually? For example, submitting /product-sitemap.xml, /product_brand-sitemap.xml versus just /sitemap.xml? Any other best practices for managing my ecommerce sitemap, or great resources, would be very helpful. Thank you! a1vUz

                      Correct linking to the /index of a site and subfolders: what's the best practice? link to: domain.com/ or domain.com/index.html ?

                      Dear all, starting with my .htaccess file: RewriteEngine On
                      RewriteCond %{HTTP_HOST} ^www.inlinear.com$ [NC]
                      RewriteRule ^(.*)$ http://inlinear.com/$1 [R=301,L] RewriteCond %{THE_REQUEST} ^./index.html 
                      RewriteRule ^(.)index.html$ http://inlinear.com/ [R=301,L] 1. I redirect all URL-requests with www. to the non www-version...
                      2. all requests with "index.html" will be redirected to "domain.com/" My questions are: A) When linking from a page to my frontpage (home) the best practice is?: "http://domain.com/" the best and NOT: "http://domain.com/index.php" B) When linking to the index of a subfolder "http://domain.com/products/index.php" I should link also to: "http://domain.com/products/" and not put also the index.php..., right? C) When I define the canonical ULR, should I also define it just: "http://domain.com/products/" or in this case I should link to the definite file: "http://domain.com/products**/index.php**" Is A) B) the best practice? and C) ? Thanks for all replies! 🙂

                      How to determine which pages are not indexed

                      Is there a way to determine which pages of a website are not being indexed by the search engines? I know Google Webmasters has a sitemap area where it tells you how many urls have been submitted and how many are indexed out of those submitted. However, it doesn't necessarily show which urls aren't being indexed.

                      Google is indexing my directories

                      I'm sure this has been asked before, but I was looking at all of Google's results for my site and I found dozens of results for directories such as: Index of /scouting/blog/wp-includes/js/swfupload/plugins Obviously I don't want those indexed. How do I prevent Google from indexing those? Also, it only seems to be doing it with Wordpress, not any of the directories on my main site. (We have a wordpress blog, which is only a portion of the site)
