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

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

What happens to crawled URLs subsequently blocked by robots.txt?
We have a very large store with 278,146 individual product pages. Since these are all various sizes and packaging quantities of less than 200 product categories my feeling is that Google would be better off making sure our category pages are indexed. I would like to block all product pages via robots.txt until we are sure all category pages are indexed, then unblock them. Our product pages rarely change, no ratings or product reviews so there is little reason for a search engine to revisit a product page. The sales team is afraid blocking a previously indexed product page will result in in it being removed from the Google index and would prefer to submit the categories by hand, 10 per day via requested crawling. Which is the better practice?

React.js Single Page Application Not Indexing
We recently launched our website that uses React.js and we haven't been able to get any of the pages indexed. Our previous site (which had a .ca domain) ranked #1 in the 4 cities we had pages and we redirected it to the .com domain a little over a month ago. We have recently started using prerender.io but still haven't seen any success. Has anyone dealt with a similar issue before?

Substantial difference between Number of Indexed Pages and Sitemap Pages
Hey there, I am doing a website audit at the moment. I've notices substantial differences in the number of pages indexed (search console), the number of pages in the sitemap and the number I am getting when I crawl the page with screamingfrog (see below). Would those discrepancies concern you? The website and its rankings seems fine otherwise. Total indexed: 2,360 (Search Consule)

Sitemap: 1,229 URLs

Google indexing only 1 page out of 2 similar pages made for different cities
We have created two category pages, in which we are showing products which could be delivered in separate cities. Both pages are related to cake delivery in that city. But out of these two category pages only 1 got indexed in google and other has not. Its been around 1 month but still only Bangalore category page got indexed. We have submitted sitemap and google is not giving any crawl error. We have also submitted for indexing from "Fetch as google" option in webmasters. www.winni.in/c/4/cakes (Indexed - Bangalore page - http://www.winni.in/sitemap/sitemap_blr_cakes.xml) 2. http://www.winni.in/hyderabad/cakes/c/4 (Not indexed - Hyderabad page - http://www.winni.in/sitemap/sitemap_hyd_cakes.xml) I tried searching for "hyderabad site:www.winni.in" in google but there also http://www.winni.in/hyderabad/cakes/c/4 this link is not coming, instead of this only www.winni.in/c/4/cakes is coming. Can anyone please let me know what could be the possible issue with this?

How can I prevent duplicate pages being indexed because of load balancer (hosting)?
The site that I am optimising has a problem with duplicate pages being indexed as a result of the load balancer (which is required and set up by the hosting company). The load balancer passes the site through to 2 different URLs: www.domain.com www2.domain.com Some how, Google have indexed 2 of the same URLs (which I was obviously hoping they wouldn't) - the first on www and the second on www2. The hosting is a mirror image of each other (www and www2), meaning I can't upload a robots.txt to the root of www2.domain.com disallowing all. Also, I can't add a canonical script into the website header of www2.domain.com pointing the individual URLs through to www.domain.com etc. Any suggestions as to how I can resolve this issue would be greatly appreciated!

What is the point of having images clickable loading to their own page?
Hello, Noticed a lot of sites, usually wordpress (seems to be the default) have the images in their posts clickable that load to their own page, showing just the image, usually a .jpg page. I know these pages seem to be easily indexed into google image search and can drive traffic to those specific pages... My questions are... 1. What is the point of driving traffic to a page that is just the image, there are no links to other pages, no ads, nothing... 2. can you redirect these .jpg pages to the actual post page? I ask because on google image search, there are 3 links to click (website, image link, image page), when you click to view the image, it loads the .jpg page, why not have that .jpg redirect to the real content page that has ads and also has other links. Is this white-hat? 3. Do these pages with just images have any negative effect on optimization since they are just images, no content? 4. Can you monetize these .jpg pages? 5. What is the best practice? I understand there is value in traffic, but what is the point of image traffic if I can't monetize those pages?

Robots.txt, does it need preceding directory structure?
Do you need the entire preceding path in robots.txt for it to match? e.g: I know if i add Disallow: /fish to robots.txt it will block /fish
Intermediate & Advanced SEO | | Milian
/fish.html
/fish/salmon.html
/fishheads
/fishheads/yummy.html
/fish.php?id=anything But would it block?: en/fish
en/fish.html
en/fish/salmon.html
en/fishheads
en/fishheads/yummy.html
**en/fish.php?id=anything (taken from Robots.txt Specifications)** I'm hoping it actually wont match, that way writing this particular robots.txt will be much easier! As basically I'm wanting to block many URL that have BTS- in such as: http://www.example.com/BTS-something
http://www.example.com/BTS-somethingelse
http://www.example.com/BTS-thingybob But have other pages that I do not want blocked, in subfolders that also have BTS- in, such as: http://www.example.com/somesubfolder/BTS-thingy
http://www.example.com/anothersubfolder/BTS-otherthingy Thanks for listening0 -
