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

URL structure - Page Path vs No Page Path
We are currently re building our URL structure for eccomerce websites. We have seen a lot of site removing the page path on product pages e.g. https://www.theiconic.co.nz/liberty-beach-blossom-shirt-680193.html versus what would normally be https://www.theiconic.co.nz/womens-clothing-tops/liberty-beach-blossom-shirt-680193.html Should we be removing the site page path for a product page to keep the url shorter or should we keep it? I can see that we would loose the hierarchy juice to a product page but not sure what is the right thing to do.

Should I use noindex or robots to remove pages from the Google index?
I have a Magento site and just realized we have about 800 review pages indexed. The /review directory is disallowed in robots.txt but the pages are still indexed. From my understanding robots means it will not crawl the pages BUT if the pages are still indexed if they are linked from somewhere else. I can add the noindex tag to the review pages but they wont be crawled. https://www.seroundtable.com/google-do-not-use-noindex-in-robots-txt-20873.html Should I remove the robots.txt and add the noindex? Or just add the noindex to what I already have?

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.

Date of page first indexed or age of a page?
Hi does anyone know any ways, tools to find when a page was first indexed/cached by Google? I remember a while back, around 2009 i had a firefox plugin which could check this, and gave you a exact date. Maybe this has changed since. I don't remember the plugin. Or any recommendations on finding the age of a page (not domain) for a website? This is for competitor research not my own website. Cheers, Paul

Should comments and feeds be disallowed in robots.txt?
Hi My robots file is currently set up as listed below. From an SEO point of view is it good to disallow feeds, rss and comments? I feel allowing comments would be a good thing because it's new content that may rank in the search engines as the comments left on my blog often refer to questions or companies folks are searching for more information on. And the comments are added regularly. What's your take? I'm also concerned about the /page being blocked. Not sure how that benefits my blog from an SEO point of view as well. Look forward to your feedback. Thanks. Eddy User-agent: Googlebot Crawl-delay: 10 Allow: /* User-agent: * Crawl-delay: 10 Disallow: /wp- Disallow: /feed/ Disallow: /trackback/ Disallow: /rss/ Disallow: /comments/feed/ Disallow: /page/ Disallow: /date/ Disallow: /comments/ # Allow Everything Allow: /*

Recovering from robots.txt error
Hello, A client of mine is going through a bit of a crisis. A developer (at their end) added Disallow: / to the robots.txt file. Luckily the SEOMoz crawl ran a couple of days after this happened and alerted me to the error. The robots.txt file was quickly updated but the client has found the vast majority of their rankings have gone. It took a further 5 days for GWMT to file that the robots.txt file had been updated and since then we have "Fetched as Google" and "Submitted URL and linked pages" in GWMT. In GWMT it is still showing that that vast majority of pages are blocked in the "Blocked URLs" section, although the robots.txt file below it is now ok. I guess what I want to ask is: What else is there that we can do to recover these rankings quickly? What time scales can we expect for recovery? More importantly has anyone had any experience with this sort of situation and is full recovery normal? Thanks in advance!

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

Could you use a robots.txt file to disalow a duplicate content page from being crawled?
A website has duplicate content pages to make it easier for users to find the information from a couple spots in the site navigation. Site owner would like to keep it this way without hurting SEO. I've thought of using the robots.txt file to disallow search engines from crawling one of the pages. Would you think this is a workable/acceptable solution?
