      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

            Customer Reviews on Product Page / Pagination / Crawl 3 review pages only

            reviews pagination crawler disallow

            Hi experts, I present customer feedback, reviews basically, on my website for the products that are sold. And with this comes the ability to read reviews and obviously with pagination to display the available reviews. Now I want users to be able to flick through and read the reviews to help them satisfy whatever curiosity they have. My only thinking is that the page that contains the reviews, with each click of the pagination will present roughly the same content. The only thing that changes is the title tags which will contain the number in the H1 to display the page number. I'm thinking this could be duplication but i have yet to be notified by Google in my Search console... Should i block crawlers from crawling beyond page 3 of reviews? Thanks

            Blog Page Titles - Page 1, Page 2 etc.

            Hi All, I have a couple of crawl errors coming up in MOZ that I am trying to fix. They are duplicate page title issues with my blog area. For example we have a URL of www.ourwebsite.com/blog/page/1 and as we have quite a few blog posts they get put onto another page, example www.ourwebsite.com/blog/page/2 both of these urls have the same heading, title, meta description etc. I was just wondering if this was an actual SEO problem or not and if there is a way to fix it. I am using Wordpress for reference but I can't see anywhere to access the settings of these pages. Thanks

            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?

            Will Adding Publish Date at end of Page Title for Blog posts Hurt SEO?

            I'd like to be able to easily track blog posts by month but in Google reports when you set a date range obviously older blog post still appear and with amount of blog posts we generate without seeing the date in the title it's not obvious what was published and when it was published. For example if a Blog Title was "/dangers-of-sharing-KM-knowledge-01-11-15 would it hurt SEO? The reason is I'd like to have a quick way to know how new posts do each month compared to older content

            When creating parent and child pages should key words be repeated in url and page title?

            We are in the direct mail advertising business:  PrintLabelAndMail.com Example: Parent:
            Postcard Direct Mail Children:
            Postcard Mailings
            Postcard Design
            Postcard Samples
            Postcard Pricing
            Postcard Advantages should "postcard" be repeated in the URL and Page Title? and in this example should each of the 5 children link back directly to the parent or would it be better to "daisy chain" them using each as parent for the next?

            What is the best way to find missing alt tags on my site (site wide - not page by page)?

            I am looking to find all the missing alt tags on my site at once. I have a FF extension that use to do it page by page, but my site is huge and that will take forever. Thanks!!

            Determining When to Break a Page Into Multiple Pages?

            Suppose you have a page on your site that is a couple thousand words long. How would you determine when to split the page into two and are there any SEO advantages to doing this like being more focused on a specific topic. I noticed the Beginner's Guide to SEO is split into several pages, although it would concentrate the link juice if it was all on one page. Suppose you have a lot of comments. Is it better to move comments to a second page at a certain point? Sometimes the comments are not super focused on the topic of the page compared to the main text.

            What's the difference between a category page and a content page

            Hello, Little confused on this matter. From a website architectural and content stand point, what is the difference between a category page and a content page? So lets say I was going to build a website around tea. My home page would be about tea. My category pages would be: White Tea, Black Tea, Oolong Team and British Tea correct? (  I Would write content for each of these topics on their respective category pages correct?) Then suppose I wrote articles on organic white tea, white tea recipes, how to brew white team etc...( Are these content pages?) Do I think link FROM my category page ( White Tea) to my ( Content pages ie; Organic White Tea, white tea receipes etc) or do I link from my content page to my category page? I hope this makes sense. Thanks, Bill
