Does google index images or ALT text only?

Nope. No need for images. They just know about the content and link to it. The cached HTML shows they store a copy (or cache) of the HTML though. I could be wrong about the images but that would exponentially increase their storage needs so it seems unlikely.

Thanks a lot. Does Google Store the images and all Html into there servers to deliver them faster?
Just to know if a copy of all content from our site is also stored on Googles servers

Hey Archie
Google indexes everything. Images. Alt text for images. Images and their alt text. If you take a look at the cached version of a page you can see all HTML content indexed. You can see the cached version of a page by prefixing the URL with info: in a google search (or in the address bar in Chrome).
info:www.example.co.uk
I suspect that is not what you are asking though and rather you want to know whether Google uses the alt text when indexing and ranking a page. Again, I would answer that Google uses (or at least tries to use) everything. They will review the context (the page), the name of the image, the alt text and anything else that may lend context (inbound links, anchors, linking pages etc).
Googles Image Publishing Guidelines page is a good read:
https://support.google.com/webmasters/answer/114016?hl=enKey takeaways from that page being:
- image name
- alt text
- on page context
- linking page context
Which of course is not to say that all of these attributes are used in all cases. I would suspect they are examined but given the general lack of useful anchors and well named images they are used when possible.
Which of course opens up a great big opportunity for those where images are a useful source of inbound traffic and competitors are using lazy CMS image names like image_z343wd.jpg and default "product image" or blank anchors.
Always difficult to answer a question without context as so many moving parts but certainly hope that helps.
Take care
Marcus

Google tries to index non existing language URLs. Why?
Hi, I am working for a SAAS client. He uses two different language versions by using two different subdomains.
Technical SEO | | TheHecksler
de.domain.com/company for german and en.domain.com for english. Many thousands URLs has been indexed correctly. But Google Search Console tries to index URLs which were never existing before and are still not existing. de.domain.com**/en/company
en.domain.com/de/**company ... and an thousand more using the /en/ or /de/ in between. We never use this variant and calling these URLs will throw up a 404 Page correctly (but with wrong respond code - we`re fixing that 😉 ). But Google tries to index these kind of URLs again and again. And, I couldnt find any source of these URLs. No Website is using this as an out going link, etc.
We do see in our logfiles, that a Screaming Frog Installation and moz.com w opensiteexplorer were trying to access this earlier. My Question: How does Google comes up with that? From where did they get these URLs, that (to our knowledge) never existed? Any ideas? Thanks 🙂0 -
Google Indexed a version of my site w/ MX record subdomain
We're doing a site audit and found "internal" links to a page in search console that appear to be from a subdomain of our site based on our MX record. We use Google Mail internally. The links ultimately redirect to our correct preferred subdomain "www", but I am concerned as to why this is happening and if it can have any negative SEO implications. Example of one of the links: Links aspmx3.googlemail.com.sullivansolarpower.com/about/solar-power-blog/daniel-sullivan/renewable-energy-and-electric-cars-are-not-political-footballs I did a site operator search, site:aspmx3.googlemail.com.sullivansolarpower.com on google and it returns several results.

Indexed pages
Just started a site audit and trying to determine the number of pages on a client site and whether there are more pages being indexed than actually exist. I've used four tools and got four very different answers... Google Search Console: 237 indexed pages Google search using site command: 468 results MOZ site crawl: 1013 unique URLs Screaming Frog: 183 page titles, 187 URIs (note this is a free licence, but should cut off at 500) Can anyone shed any light on why they differ so much? And where lies the truth?

How can I get a photo album indexed by Google?
We have a lot of photos on our website. Unfortunately most of them don't seem to be indexed by Google. We run a party website. One of the things we do, is take pictures at events and put them on the site. An event page with a photo album, can have anywhere between 100 and 750 photo's. For each foto's there is a thumbnail on the page. The thumbnails are lazy loaded by showing a placeholder and loading the picture right before it comes onscreen. There is no pagination of infinite scrolling. Thumbnails don't have an alt text. Each thumbnail links to a picture page. This page only shows the base HTML structure (menu, etc), the image and a close button. The image has a src attribute with full size image, a srcset with several sizes for responsive design and an alt text. There is no real textual content on an image page. (Note that when a user clicks on the thumbnail, the large image is loaded using JavaScript and we mimic the page change. I think it doesn't matter, but am unsure.) I'd like that full size images should be indexed by Google and found with Google image search. Thumbnails should not be indexed (or ignored). Unfortunately most pictures aren't found or their thumbnail is shown. Moz is giving telling me that all the picture pages are duplicate content (19,521 issues), as they are all the same with the exception of the image. The page title isn't the same but similar for all images of an album. Example: On the "A day at the park" event page, we have 136 pictures. A site search on "a day at the park" foto, only reveals two photo's of the albums. 3QolbbI.png QTQVxqY.jpg mwEG90S.jpg

Hosting images externally
In these days of CDNs does it matter for SEO whether images (and PDFs etc.) are hosted off-site? Does it make a difference if images hosted on Flickr, photobucket etc. Thanks

CDN Being Crawled and Indexed by Google
I'm doing a SEO site audit, and I've discovered that the site uses a Content Delivery Network (CDN) that's being crawled and indexed by Google. There are two sub-domains from the CDN that are being crawled and indexed. A small number of organic search visitors have come through these two sub domains. So the CDN based content is out-ranking the root domain, in a small number of cases. It's a huge duplicate content issue (tens of thousands of URLs being crawled) - what's the best way to prevent the crawling and indexing of a CDN like this? Exclude via robots.txt? Additionally, the use of relative canonical tags (instead of absolute) appear to be contributing to this problem as well. As I understand it, these canonical tags are telling the SEs that each sub domain is the "home" of the content/URL. Thanks! Scott

Google Cache Version and Text Only Version are different
Across various websites we found Google cache version in the browser loads the full site and all content is visible. However when we try to view TEXT only version of the same page we can't see any content. Example: we have a client with JS scroller menu on the home page. Each scroller serves a separate content section on the same URL. When we copy paste some of the page content in Google, we can see that copy indexed in Google search results as well as showing in Cache version . But as soon as we go into Text Only version we cant see the same copy. We would like to know which version we should trust, Google cache version or the TEXT only version.
