If Robots.txt have blocked an Image (Image URL) but the other page which can be indexed has this image, how is the image treated?
-
Hi MOZers,
This probably is a dumb question but I have a case where the robots.tags has an image url blocked but this image is used on a page (lets call it Page A) which can be indexed. If the image on Page A has an Alt tags, then how is this information digested by crawlers?
A) would Google totally ignore the image and the ALT tags information? OR
B) Google would consider the ALT tags information?
I am asking this because all the images on the website are blocked by robots.txt at the moment but I would really like website crawlers to crawl the alt tags information. Chances are that I will ask the webmaster to allow indexing of images too but I would like to understand what's happening currently.
Looking forward to all your responses
Malika

May I ask why you/your webmaster would have noindexed your images in the first place?

Hi Malika,
Blocking image directories or images themselves in robots.txt only prevents the image from being added to "image" search results. You will still get the full benefit of the alt text on the page, the image just won't appear in the image results.
How this actually works is the crawler will crawl the site and index all the text and weight (h1, h2, alt etc..) then when the crawler moves to add the image to the search cache it finds it can't access it due to robots.txt and simply ignores it and goes on.This leaves your original text as what is indexed as a search result, and nothing for image results.
If you are using Apache you may want to not use robots.txt as the method of blocking images. I would recommend using the .htaccess file with a code like this...
<filesmatch ".(bmp|gif|jpg|png|tif)$"="">Header set X-Robots-Tag "noindex"</filesmatch>
This is a blanket declaration and would prevent indexing of any images with the noted extensions on your site. This is particularly useful if you have multiple image directories. Further more if there are a few images you want indexed you could pick a particular extension like .jpeg for example (note jpeg not jpg), then just convert those few images and know they will be indexed as they are not in the exclusion list.
Another benefit of handling it this way is if you already have images that are indexed, using the noindex tag will get them out out of the image directory much faster than blocking them. The reason is you are giving Google a new directive which is "noindex", otherwise they will just treat them as inaccessible and move on, leaving any cached version to appear in the directory for some time.
Hope that makes sense and helps,
Don

E-Commerce Site Collection Pages Not Being Indexed
Hello Everyone, So this is not really my strong suit but I’m going to do my best to explain the full scope of the issue and really hope someone has any insight. We have an e-commerce client (can't really share the domain) that uses Shopify; they have a large number of products categorized by Collections. The issue is when we do a site:search of our Collection Pages (site:Domain.com/Collections/) they don’t seem to be indexed. Also, not sure if it’s relevant but we also recently did an over-hall of our design. Because we haven’t been able to identify the issue here’s everything we know/have done so far: Moz Crawl Check and the Collection Pages came up. Checked Organic Landing Page Analytics (source/medium: Google) and the pages are getting traffic. Submitted the pages to Google Search Console. The URLs are listed on the sitemap.xml but when we tried to submit the Collections sitemap.xml to Google Search Console 99 were submitted but nothing came back as being indexed (like our other pages and products). We tested the URL in GSC’s robots.txt tester and it came up as being “allowed” but just in case below is the language used in our robots:

Wrong URLs indexed, Failing To Rank Anywhere
I’m struggling with a client website that's massively failing to rank. It was published in Nov/Dec last year - not optimised or ranking for anything, it's about 20 pages. I came onboard recently, and 5-6 weeks ago we added new content, did the on-page and finally changed from the non-www to the www version in htaccess and WP settings (while setting www as preferred in Search Console). We then did a press release and since then, have acquired about 4 partial match contextual links on good websites (before this, it had virtually none, save for social profiles etc.) I should note that just before we added the (about 50%) new content and optimised, my developer accidentally published the dev site of the old version of the site and it got indexed. He immediately added it correctly to robots.txt, and I assumed it would therefore drop out of the index fairly quickly and we need not be concerned. Now it's about 6 weeks later, and we’re still not ranking anywhere for our chosen keywords. The keywords are around “egg freezing,” so only moderate competition. We’re not even ranking for our brand name, which is 4 words long and pretty unique. We were ranking in the top 30 for this until yesterday, but it was the press release page on the old (non-www) URL! I was convinced we must have a duplicate content issue after realising the dev site was still indexed, so last week, we went into Search Console to remove all of the dev URLs manually from the index. The next day, they were all removed, and we suddenly began ranking (~83) for “freezing your eggs,” one of our keywords! This seemed unlikely to be a coincidence, but once again, the positive sign was dampened by the fact it was non-www page that was ranking, which made me wonder why the non-www pages were still even indexed. When I do site:oursite.com, for example, both non-www and www URLs are still showing up…. Can someone with more experience than me tell me whether I need to give up on this site, or what I could do to find out if I do? I feel like I may be wasting the client’s money here by building links to a site that could be under a very weird penalty 😕

Does Google Index URLs that are always 302 redirected
Hello community Due to the architecture of our site, we have a bunch of URLs that are 302 redirected to the same URL plus a query string appended to it. For example: www.example.com/hello.html is 302 redirected to www.example.com/hello.html?___store=abc The www.example.com/hello.html?___store=abc page also has a link canonical tag to www.example.com/hello.html In the above example, can www.example.com/hello.html every be Indexed, by google as I assume the googlebot will always be redirected to www.example.com/hello.html?___store=abc and will never see www.example.com/hello.html ? Thanks in advance for the help!

Image URLs - best practice
Hi - I'm assuming image URL best practice follows same principles as non image URLs (not too many files and so on) - I notice alot of web devs putting photos in subdomains, so wonder if I'm missing something (I usually avoid subdomains like the plague)!

Are pages with a canonical tag indexed?
Hello here, here are my questions for you related to the canonical tag: 1. If I put online a new webpage with a canonical tag pointing to a different page, will this new page be indexed by Google and will I be able to find it in the index? 2. If instead I apply the canonical tag to a page already in the index, will this page be removed from the index? Thank you in advance for any insights! Fabrizio

Block an entire subdomain with robots.txt?
Is it possible to block an entire subdomain with robots.txt? I write for a blog that has their root domain as well as a subdomain pointing to the exact same IP. Getting rid of the option is not an option so I'd like to explore other options to avoid duplicate content. Any ideas?
