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

Robots.txt blocked internal resources Wordpress
Hi all, We've recently migrated a Wordpress website from staging to live, but the robots.txt was deleted. I've created the following new one: User-agent: *
Intermediate & Advanced SEO | | Mat_C
Allow: /
Disallow: /wp-admin/
Disallow: /wp-includes/
Disallow: /wp-content/plugins/
Disallow: /wp-content/cache/
Disallow: /wp-content/themes/
Allow: /wp-admin/admin-ajax.php However, in the site audit on SemRush, I now get the mention that a lot of pages have issues with blocked internal resources in robots.txt file. These blocked internal resources are all cached and minified css elements: links, images and scripts. Does this mean that Google won't crawl some parts of these pages with blocked resources correctly and thus won't be able to follow these links and index the images? In other words, is this any cause for concern regarding SEO? Of course I can change the robots.txt again, but will urls like https://example.com/wp-content/cache/minify/df983.js end up in the index? Thanks for your thoughts!2 -
No Index thousands of thin content pages?
Hello all! I'm working on a site that features a service marketed to community leaders that allows the citizens of that community log 311 type issues such as potholes, broken streetlights, etc. The "marketing" front of the site is 10-12 pages of content to be optimized for the community leader searchers however, as you can imagine there are thousands and thousands of pages of one or two line complaints such as, "There is a pothole on Main St. and 3rd." These complaint pages are not about the service, and I'm thinking not helpful to my end goal of gaining awareness of the service through search for the community leaders. Community leaders are searching for "311 request service", not "potholes on main street". Should all of these "complaint" pages be NOINDEX'd? What if there are a number of quality links pointing to the complaint pages? Do I have to worry about losing Domain Authority if I do NOINDEX them? Thanks for any input. Ken

Redirected Old Pages Still Indexed
Hello, we migrated a domain onto a new Wordpress site over a year ago. We redirected (with plugin: simple 301 redirects) all the old urls (.asp) to the corresponding new wordpress urls (non-.asp). The old pages are still indexed by Google, even though when you click on them you are redirected to the new page. Can someone tell me reasons they would still be indexed? Do you think it is hurting my rankings?

Can I tell Google to Ignore Parts of a Page?
Hi all, I was wondering if there was some sort of html trick that I could use to selectively tell a search engine to ignore texts on certain parts of a page. Thanks!

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

Where to put a page ID in a URL?
Hello, My company is going to change URLs to example.com/category or example.com/product. When we will change the URLs to product or category pages somehow we have to check whether the requested page is from category table in DB or from products table (this gives much speed to page load time). So we have to choose how to make the different product and category pages.

Programmers said that we need to insert id to URL. So the question is: Which is the better way to place an id to an URL? example.com/product-name?id=111 example.com/product-name/111 example.com/product_name-111 Or maybe we should use some other punctuation mark to separate id from product name? p.s. I have read Dynamic URLs vs. static URLs by Google and it still didn't answered which is the best for all of the pages. Somehow others solve this problem by typing only the names to the URL, but could anyone tell what that technology should be?0 -
Does Google index url with hashtags?
We are setting up some Jquery tabs in a page that will produce the same url with hashtags. For example: index.php#aboutus, index.php#ourguarantee, etc. We don't want that content to be crawled as we'd like to prevent duplicate content. Does Google normally crawl such urls or does it just ignore them? Thanks in advance.
