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?

Can google bots read my internal post links if they are all listed in a javascript accordian where I list my sources?
I post a JavaScript accordion drop down tab [ a collapsible content area ] at the end of all my posts. I labeled the accordion "Show Article Sources"., and when a user clicks it, then the accordion expands open and it shows all the sources I listed for my article. And this is where I post all of my articles links that I reference per each article. But I read somewhere that google crawlers can not read text in a drop down JavaScript tab. So I am wondering now if this is true because that would mean I have no internal linking SEO going on since it cant read the links? ..... if it is true, then I should remove the accordion from all my articles and some how include the links I reference in the actual body text so I can get SEO benefits from external linking similar content? If that's true, what is an aesthetic way to do this, any example links? Tips ? Thoughts ?

My Homepage Won't Load if Javascript is Disabled. Is this an SEO/Indexation issue?
Hi everyone, I'm working with a client who recently had their site redesigned. I'm just going through to do an initial audit to make sure everything looks good. Part of my initial indexation audit goes through questions about how the site functions when you disable, javascript, cookies, and/or css. I use the Web Developer extension for Chrome to do this. I know, more recently, people have said that content loaded by Javascript will be indexed. I just want to make sure it's not hurting my clients SEO. http://americasinstantsigns.com/ Is it as simple as looking at Google's Cached URL? The URL is definitely being indexed and when looking at the text-only version everything appears to be in order. This may be an outdated question, but I just want to be sure! Thank you so much!

Javascript tabbed navigation and duplicate content
I'm working on a site that has four primary navigation links and under each is a tabbed navigation system for second tier items. The primary link page loads content for all tabs which are javascript controlled. Users will click the primary navigation item "Our Difference" (http://www.holidaytreefarm.com/content.cfm/Our-Difference) and have several options with each tabs content in separate sections. Each second tier tab is also available via sitemap/direct link (ie http://www.holidaytreefarm.com/content.cfm/Our-Difference/Tree-Logistics) without the js navigation so the content on this page is specific to the tab, not all tabs. In this scenario, will there be duplicate content issues? And, what is the best way to remedy this? Thanks for your help!

Does Google Read Javascript?
I would like to include a list of links in a select type box which I would like google to follow. In order to do this, I will be styling it with the help of javascript, and in turn change the select box into a ul and the options into li's. The li's would each contain a link, but if javascript is disabled it will fallback to a normal css styled select box. My question is would google follow the links made by the javascript? Or would the bot just recognize the select box as a select box and not links. Thanks for any help!

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 bad for SEO?
If we utilize javascript to pull information from a database to display on a site, is that bad for SEO? Can search engines still see the data?
