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!

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

Yeah let me point you to some resources on this:
http://www.seomoz.org/ugc/new-reality-google-follows-links-in-javascript-4930
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.

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

All other things equal, do server rendered websites rank higher than JavaScript web apps that follow the AJAX Crawling Spec?
I instinctively feel like server rendered websites should rank higher since Google doesn't truly know that the content its getting from an AJAX site is what the user is seeing and Google isn't exactly sure of the page load time (and thus user experience). I can't find any evidence that would prove this, however. A website like Monocle.io uses pushstate, loads fast, has good page titles, etc., but it is a JavaScript single page application. Does it make any difference?

Javascript usage
Hi Guys, I know that since a couple years Google can crawl and read better Javascript(JS), but JS can still harm your website especially in the navigational bar but I don't know how to identify it. Can Someone tell me how to identify in the source page when JS can harm your website?

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!

Is use of javascript to simplify information architecture considered cloaking?
We are considering using javascript to format URLs to simplify the navigation of the googlebot through our site, whilst presenting a larger number of links for the user to ensure content is accessible and easy to navigate from all parts of the site. In other words, the user will see all internal links, but the search engine will see only those links that form our information hierarchy. We are therefore showing the search engine different content to the user only in so far as the search engine will have a more hierarchical information architecture by virture of the fact that there will be fewer links visible to the search engine to ensure that our content is well structured and discoverable. Would this be considered cloaking by google and would we be penalised?
