      Hello all,
      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
      Luca

        Hi Luca! So sorry for the wait. Yes, Google is able to load, crawl, and index pages written in Javascript. There are mixed reports as to how well, exactly, but your research is correct.

          I have done my homework researching.
          As a matter of fact since 2010 Google can crawl and execute JavaScript links, therefore the pages will be indexed and ranked exactly as static HTML pages.

          It would be nice to have confirmation on this

            Static or dynamic category pages for seo

            Hi, I'm developing an accommodation site with a limited number of properties in 8 categories.  I had been looking at making the properties blog posts and then using category function to show lists but its going to require a lot of customisation and I have seo concerns about the dynamic content as the category page is crucial. As I don't have a lot to add and listings will remain the same my latest thought was to create all as pages.  However if I create a page with a list of 12 properties on a category page is there anyway of adding some sorting criteria to that page (would be 7 options - swimming pool, near beach, on site creche, budget, mid-range, luxury) Thanks for any tips Neil

            SEO impact of the anatomy of URL subdirectory structure?

            I've been pushing hard to get our Americas site (DA 34) integrated with our higher domain authority (DA 51) international website. Currently our international website is setup in the following format... website.com/us-en/ website.com/fr-fr/ etc... The problem that I am facing is that I need my development framework installed in it's own directory. It cannot be at the root of the website (website.com) since that is where the other websites (us-en, fr-fr, etc.) are being generated from. Though we will have control of /us-en/ after the integration I cannot use that as the website main directory since the americas website is going to be designed for scalability (eventually adopting all regions and languages) so it cannot be region specific. What we're looking at is website.com/[base]/us-en. I'm afraid that if base has any length to it in terms of characters it is going to dilute the SEO value of whatever comes after it in the URL (website.com/[base]/us-en/store/product-name.html). Any recommendations?

            Why is Google Webmaster Tools showing 404 Page Not Found Errors for web pages that don't have anything to do with my site?

            I am currently working on a small site with approx 50 web pages.  In the crawl error section in WMT Google has highlighted over 10,000 page not found errors for pages that have nothing to do with my site.  Anyone come across this before?

            SEO-impact of mouseover text on header pictures

            Hi, what do you reckon of taking away the mouseover effect on the header pictures seen on www.viventura.de/reisen/peru?
            We are thinking of eliminating the mouseover text to make User Experience even better but are worrying that our ranking might go down when doing so. Any experiences, any help is highly appreciated!
            Thanks, Benno

            Is the Authority of Individual Pages Diluted When You Add New Pages?

            I was wondering if the authority of individual pages is diluted when you add new pages (in Google's view). Suppose your site had 100 pages and you added 100 new pages (without getting any new links). Would the average authority of the original pages significantly decrease and result in a drop in search traffic to the original pages? Do you worry that adding more pages will hurt pages that were previously published?

            How much will changing IP addresses impact SEO?

            So my company is upgrading its Internet bandwidth.  However, apparently the vendor has said that part of the upgrade will involve changing our IP address.  I've found two links that indicate some care needs to be taken to make sure our SEO isn't harmed: http://followmattcutts.com/2011/07/21/protect-your-seo-when-changing-ip-address-and-server/ http://www.v7n.com/forums/google-forum/275513-changing-ip-affect-seo.html Assuming we don't use an IP address that has been blacklisted by Google for spamming or other black hat tactics, how problematic is it? (Note: The site hasn't really been aggressively optimized yet - I started with the company less than two weeks ago, and just barely got FTP and CMS access yesterday - so honestly I'm not too worried about really messing up the site's optimization, since there isn't a lot to really break.)

            What SEO considerations for multiple languages on a single page?

            I am working on a language teaching site for Chinese speakers learning English. I consider myself above average when it comes to basic SEO issues, but all I know here is that Google doesn't like multiple languages on a single page. Without getting into too many details, both Chinese and English text will appear on the same page with links, tags, phonetic spellings, etc. I'm hoping someone here knows the science about using the lang="zh" xml:lang="zh" attributes within text and the effects on ranking for text within the declarations. And it'd be great if there was clarification on the link juice passed using the hreflang attribute for both internal and external links. Also, of course, any info on using both English and Chinese characters in the URL would be most helpful. A heads up on any other language specific SEO issues would also be much appreciated. My goal is to get the most out of both languages per page in terms of ranking.
