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

Vanity URLs are being indexed in Google
We are currently using vanity URLs to track offline marketing, the vanity URL is structured as www.clientdomain.com/publication, this URL then is 302 redirected to the actual URL on the website not a custom landing page. The resulting redirected URL looks like: www.clientdomain.com/xyzpage?utm_source=print&utm_medium=print&utm_campaign=printcampaign. We have started to notice that some of the vanity URLs are being indexed in Google search. To prevent this from happening should we be using a 301 redirect instead of a 302 and will the Google index ignore the utm parameters in the URL that is being 301 redirect to? If not, any suggestions on how to handle? Thanks,

Blocked URL parameters can still be crawled and indexed by google?
Hy guys, I have two questions and one might be a dumb question but there it goes. I just want to be sure that I understand: IF I tell webmaster tools to ignore an URL Parameter, will google still index and rank my url? IS it ok if I don't append in the url structure the brand filter?, will I still rank for that brand? Thanks, PS: ok 3 questions :)...

Staging & Development areas should be not indexable (i.e. no followed/no index in meta robots etc)
Hi I take it if theres a staging or development area on a subdomain for a site, who's content is hence usually duplicate then this should not be indexable i.e. (no-indexed & nofollowed in metarobots) ? In order to prevent dupe content probs as well as non project related people seeing work in progress or finding accidentally in search engine listings ? Also if theres no such info in meta robots is there any other way it may have been made non-indexable, or at least dupe content prob removed by canonicalising the page to the equivalent page on the live site ? In the case in question i am finding it listed in serps when i search for the staging/dev area url, so i presume this needs urgent attention ? Cheers Dan

How Does Google's "index" find the location of pages in the "page directory" to return?
This is my understanding of how Google's search works, and I am unsure about one thing in specific: Google continuously crawls websites and stores each page it finds (let's call it "page directory") Google's "page directory" is a cache so it isn't the "live" version of the page Google has separate storage called "the index" which contains all the keywords searched. These keywords in "the index" point to the pages in the "page directory" that contain the same keywords. When someone searches a keyword, that keyword is accessed in the "index" and returns all relevant pages in the "page directory" These returned pages are given ranks based on the algorithm The one part I'm unsure of is how Google's "index" knows the location of relevant pages in the "page directory". The keyword entries in the "index" point to the "page directory" somehow. I'm thinking each page has a url in the "page directory", and the entries in the "index" contain these urls. Since Google's "page directory" is a cache, would the urls be the same as the live website (and would the keywords in the "index" point to these urls)? For example if webpage is found at wwww.website.com/page1, would the "page directory" store this page under that url in Google's cache? The reason I want to discuss this is to know the effects of changing a pages url by understanding how the search process works better.

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.

Instant Indexing
I've been working on a site for a while now, methodically building content and building trust and authority. Lately I've noticed that anything I publish there appears to be instantly indexed by Google, which surprises me. I haven't had this happen before so I'm curious. I'd be interested to hear the experience of others.

Index forum sites
Hi Moz Team, somehow the last question i raised a few days ago not only wasnt answered up until now, it was also completely deleted and the credit was not "refunded" - obviously there was some data loss involved with your restructuring. Can you check whether you still find the last question and answer it quickly? I need the answer 🙂 Here is one more question: I bought a website that has a huge forum, loads of pages with user generated content. Overall around 500.000 Threads with 9 Million comments. The complete forum is noindex/nofollow when i bought the site, now i am thinking about what is the best way to unleash the potential. The current system is vBulletin 3.6.10. a) Shall i first do an update of vbulletin to version 4 and use the vSEO tool to make the URLs clean, more user and search engine friendly before i switch to index/follow? b) would you recommend to have the forum in the folder structure or on a subdomain? As far as i know subdomain does take lesser strenght from the TLD, however, it is safer because the subdomain is seen as a separate entity from the regular TLD. Having it in he folder makes it easiert to pass strenght from the TLD to the forum, however, it puts my TLD at risk c) Would you release all forum sites at once or section by section? I think section by section looks rather unnatural not only to search engines but also to users, however, i am afraid of blasting more than a millionpages into the index at once. d) Would you index the first page of a threat or all pages of a threat? I fear duplicate content as the different pages of the threat contain different body content but the same Title and possibly the same h1. Looking forward to hear from you soon! Best Fabian
