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

Google Indexing Of Pages As HTTPS vs HTTP
We recently updated our site to be mobile optimized. As part of the update, we had also planned on adding SSL security to the site. However, we use an iframe on a lot of our site pages from a third party vendor for real estate listings and that iframe was not SSL friendly and the vendor does not have that solution yet. So, those iframes weren't displaying the content. As a result, we had to shift gears and go back to just being http and not the new https that we were hoping for. However, google seems to have indexed a lot of our pages as https and gives a security error to any visitors. The new site was launched about a week ago and there was code in the htaccess file that was pushing to www and https. I have fixed the htaccess file to no longer have https. My questions is will google "reindex" the site once it recognizes the new htaccess commands in the next couple weeks?

My blog is indexing only the archive and category pages
Hi there MOZ community. I am new to the QandA and have a question. I have a blog Its been live for months - but I can not get the posts to rank in the serps. Oddly only the categories rank. The posts are crawled it seems - but seen as less important for a reason I don't understand. Can anyone here help with this? See here for what i mean. I have had several wp sites rank well in the serps - and the posts do much better. Than the categories or archives - super odd. Thanks to all for help!

URL Injection Hack - What to do with spammy URLs that keep appearing in Google's index?
A website was hacked (URL injection) but the malicious code has been cleaned up and removed from all pages. However, whenever we run a site:domain.com in Google, we keep finding more spammy URLs from the hack. They all lead to a 404 error page since the hack was cleaned up in the code. We have been using the Google WMT Remove URLs tool to have these spammy URLs removed from Google's index but new URLs keep appearing every day. We looked at the cache dates on these URLs and they are vary in dates but none are recent and most are from a month ago when the initial hack occurred. My question is...should we continue to check the index every day and keep submitting these URLs to be removed manually? Or since they all lead to a 404 page will Google eventually remove these spammy URLs from the index automatically? Thanks in advance Moz community for your feedback.

Removing UpperCase URLs from Indexing
This search - site:www.qjamba.com/online-savings/automotix gives me this result from Google: Automotix online coupons and shopping - Qjamba
Intermediate & Advanced SEO | | friendoffood
https://www.qjamba.com/online-savings/automotix
Online Coupons and Shopping Savings for Automotix. Coupon codes for online discounts on Vehicles & Parts products. and Google tells me there is another one, which is 'very simliar'. When I click to see it I get: Automotix online coupons and shopping - Qjamba
https://www.qjamba.com/online-savings/Automotix
Online Coupons and Shopping Savings for Automotix. Coupon codes for online discounts on Vehicles & Parts products. This is because I recently changed my program to redirect all urls with uppercase in them to lower case, as it appears that all lowercase is strongly recommended. I assume that having 2 indexed urls for the same content dilutes link juice. Can I safely remove all of my UpperCase indexed pages from Google without it affecting the indexing of the lower case urls? And if, so what is the best way -- there are thousands.0 -
Using Canonical URL to poin to an external page

How can I get a list of every url of a site in Google's index?
I work on a site that has almost 20,000 urls in its site map. Google WMT claims 28,000 indexed and a search on Google shows 33,000. I'd like to find what the difference is. Is there a way to get an excel sheet with every url Google has indexed for a site? Thanks... Mike

Links from non-indexed pages
Whilst looking for link opportunities, I have noticed that the website has a few profiles from suppliers or accredited organisations. However, a search form is required to access these pages and when I type cache:"webpage.com" the page is showing up as non-indexed. These are good websites, not spammy directory sites, but is it worth trying to get Google to index the pages? If so, what is the best method to use?

Getting Pages Requiring Login Indexed
Somehow certain newspapers' webpages show up in the index but require login. My client has a whole section of the site that requires a login (registration is free), and we'd love to get that content indexed. The developer offered to remove the login requirement for specific user agents (eg Googlebot, et al.). I am afraid this might get us penalized. Any insight?
