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.

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!

I am Using Wix website creator. Will google be able to read the javascript?
I tried using some of the moz tools like the "on page grader" and it was not able to read any of the writing on my webpage because wix uses javascript. Will this impact my rankings on google compared to my competitors? The New Wix websites allow you to build a website in HTML. Should I switch to this? Thanks, Jonathan

Javascript redirects -- what are the SEO pitfalls?
Q: Is it dangerous (SEO fallout) to use javascript redirects? Tech team built a browser side tool for me to easily redirect old/broken links. This is essentially a glorified 400 page -- pops a quick message that the page requested no longer exists and that we're automatically sending you to a page that has the content you are looking. Tech team does not have the bandwidth to handle this via apache and this tool is what they came up with for me to deliver a better customer experience. Back story: very large site and I'm dealing with thousands of pages that could/should/need to be redirected. My issue is incredibly similar to what Rand mentioned way back in a post from 2009: Are 404 Pages Always Bad for SEO? We've also decided to let these pages 404 and monitor for anything that needs an apache redirect. Tool mentioned above was tech's idea to give me "the power" to manage redirects. What do you think?

Dynamically changing a title with javascript
Hi, I asked our IT team to be able to write custom page titles in our CMS and they came up with a solution that writes the title dynamically with javascript. When I look on the page, I see the title in the browser, but when I look in the source code, I see the original page title. I am thinking that Google won't see the new javascript title, so it will not be indexed and have no impact on SEO. Am I right ?

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>

We have just completed the redesign of our product page, which you can see here: http://www.uksoccershop.com/p-19045/2011-12-Chelsea-Adidas-Away-Football-Shirt.html Because we want the select size / add to basket section to appear prominently, you can see we are showing only a snippet of the product description in this section and then user has to click "more" to see it.

How much javascript does Googlebot read
We have a site where we have certain navigational links solely for the human user. These links help the user experience and lead to pages that we don't need crawled by googlebot. We have these links in javascript so if you disable javascript these links are invisible. Will these links be considered cloaking even though our intention is not to cloak but save our Google crawl for pages we do want indexed?

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.
