Javascript

Hi mozzers,
For my website I use various affiliate programs on commission junction. Some of the text ads are in javascript. Will google read the text ads or not?
Cheers,

Again, great resources, Daniel. The first link provides some empirical evidence that ajax based links do get interpreted. SEOmofo had a nice recommendation that should stop google from indexing your JS if need be. He basically said put your JS in an external file that you disallow in robots.txt.
From your second link
The search appliance only executes scripts embedded inside a document. The search appliance does not support:
- DOM tracking to support calls, such as
document.getElementById
- External scripts execution
- AJAX execution
Not exactly sure what "AJAX execution" means. However, if it means downloading JSON or JS and evaluating it that makes sense. Perhaps not external JS gets executed by google?
The third link discusses the "agreement" you can make with a crawler if you have an ajax based site using hash bang urls. Not super relevant for me but good to know so thanks!
- DOM tracking to support calls, such as

Thanks very much for this. Can't wait to check these resources out.

Yeah let me point you to some resources on this:

Your best resource is from Google here:
To your question though, I do believe Google will execute external javascript files. Ajax stuff I'm not as sure about. They have a primer on this here:
<cite>code.google.com/web/ajaxcrawling/docs/learn-more.html</cite>
The 90% thing I recall from SMX advanced last year I believe. Basically people would try to hide internal links in javascript since using nofollow for pagerank sculpting was debunked by Matt Cutts in 2009. Turned out Google could see most links being created in javascript.
You can read up on that second link there in javascript crawling from Google and it goes into a lot of detail about what they can do, hope it helps.

Hey Daniel,
Would you mind diving into that statement a little more? I didn't realize that Google could execute 90% of javascript. Do you think they will load in external javascript files? Does google make ajax calls?
I only ask the questions b/c I have a web site who's home page that has too many links and too much HTML. I'd love to use javascript to do some progressive rendering and keep some links and additonal HTML out of the initial HTTP response sent back when someone requests a page on our site.
Thanks in advance!

very helpful thanks!

Google has said they can execute about 90% or so of all javascript at this point, so there is a good chance Google will be able to see these affiliate links, even if they are being done in javascript.

What are best options for website built with navigation drop-down menus in JavaScript, to get those menus indexed by Google?
This concerns f5.com, a large website with navigation menus that drop down when hovered over. The sub nav items (example: “DDoS Protection”) are not cached by Google and therefore do not distribute internal links properly to help those sub-pages rank well. Best option naturally is to change the nav menus from JS to CSS but barring that, is there another option? Will Schema SiteNavigationElement work as an alternate?

JavaScript page loader - SEO impact
Hello all,
Technical SEO | | Lvet
I am working on a site that has a bizarre page load system. All pages get loaded trough the same Javascript snippet, for example: Changing the values in the form changes the page that is loaded. The most incredible thing is that, against my expectations, pages do get indexed by Google.
My question is: "Does loading pages dynamically using JavaScript affect the overall SEO performance?" Why are pages getting indexed? Thank you for shedding light on this.
Cheers

Javascript void and PageRank
Do javascript void links to on-page elements (not to a new page) consume PageRank? I'm paring down links on a client's homepage, and we have javascript void links (wrapped in <a href="">) that load videos, elements of a slider, etc. on the page itself.</a> <a href="">Basically, if I have a bunch of these, is it going to weaken the power of the other links on the page?</a>

Optimizing a website which uses JavaScript and jQuery
Just a quick question (or 2) If I have divs which are hidden on my page, but are displayed when a user clicks on a p tag and the hidden div is displayed using jquery a user clicks on an a tag and the hidden div is displayed using jquery with the href being cancelled in both examples, will the hidden content be optimized, or will the fact it is initially hidden make it harder to optimize? Thanks for any answers!

Javascript funtion as link? Why not show up?
We joined our Chamber of Commerce for the "link" as much as anything. After 9 months of having a link from our local chamber it has never showed up anywhere. You can see the link on my Chambers page, and you can click on it and it works. But it does not show up anywhere else....Not in any backlink checker, not in SEOmoz, not in Google Webmaster Tools. When I hover over our link on their page I see "javascript:encodeclick........my url" Is this link worth anything? What is a javascriptencodeclick? Does Google know it exists and give me credit for it? Our Chamber is clueless... they hire someone to do their website. Their webmasters response to my question was: Hi, These links look like this because this is just the way our system parses URLs that are entered into the membership directory so they can be clickable when displayed in the lister. These links will not have a negative effect on Google or SEO indexing purposes if that is what you are concerned about. They are not encoded or encrypted, this just happens to be the name of the Javascript function.
