      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?

                      Express js and SEO?

                      Hi fellow Mozzers, I have been tasked with providing some SEO recommendations for a website that is to be built using express.js and Angular.  I wondered whether anyone has had any experience in such a framework? On checking a website built in this and viewing as a GoogleBot etc using the following tools it appears as though most of the content is invisible: http://www.webconfs.com/search-engine-spider-simulator.php http://www.browseo.net/ Obviously this is a huge issue and wonder if there are any workarounds, or reccomendations to assist (even if means moving away from this  - would love to hear about it)

                      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

                      No index on subdomains

                      Hi, We have a subdomain that is appearing in the search results - I want to hide this as it looks really bad. If I were to add the no index tag to the sub domain would URL would this affect the whole domain or just that sub domain? The main domain is vitally important - it is just that sub domain I need to hide. Many thanks

                      CDN Being Crawled and Indexed by Google

                      I'm doing a SEO site audit, and I've discovered that the site uses a Content Delivery Network (CDN) that's being crawled and indexed by Google. There are two sub-domains from the CDN that are being crawled and indexed. A small number of organic search visitors have come through these two sub domains. So the CDN based content is out-ranking the root domain, in a small number of cases. It's a huge duplicate content issue (tens of thousands of URLs being crawled) - what's the best way to prevent the crawling and indexing of a CDN like this? Exclude via robots.txt? Additionally, the use of relative canonical tags (instead of absolute) appear to be contributing to this problem as well. As I understand it, these canonical tags are telling the SEs that each sub domain is the "home" of the content/URL. Thanks! Scott

                      Removing URL Parentheses in HTACCESS

                      Im reworking a website for a client, and their current URLs have parentheses. I'd like to get rid of these, but individual 301 redirects in htaccess is not practical, since the parentheses are located in many URLs. Does anyone know an HTACCESS rule that will simply remove URL parantheses as a 301 redirect?
