      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

            Does a no-indexed parent page impact its child pages?

            If I have a page* in WordPress that is set as private and is no-indexed with Yoast, will that negatively affect the visibility of other pages that are set as children of that first page? *The context is that I want to organize some of the pages on a business's WordPress site into silos/directories. For example, if the business was a home remodeling company, it'd be convenient to keep all the pages about bathrooms, kitchens, additions, basements, etc. bundled together under a "services" parent page (/services/kitchens/, /services/bathrooms/, etc.). The thing is that the child pages will all be directly accessible from the menus, so there doesn't need to be anything on the parent /services/ page itself. Another such parent page/directory/category might be used to keep different photo gallery pages together (/galleries/kitchen-photos/, /galleries/bathroom-photos/, etc.). So again, would it be safe for pages like /services/kitchens/ and /galleries/addition-photos/ if the /services/ and /galleries/ pages (but not /galleries/* or anything like that) are no-indexed? Thanks!

            Home Page Ranking Instead of Service Pages

            Hi everyone! I've noticed that many of our clients have pages addressing specific queries related to specific services on their websites, but that the Home Page is increasingly showing as the "ranking" page. For example, a plastic surgeon we work with has a page specifically talking about his breast augmentation procedure for Miami, FL but instead of THAT page showing in the search results, Google is using his home page. Noticing this across the board. Any insights? Should we still be optimizing these specific service pages? Should I be spending time trying to make sure Google ranks the page specifically addressing that query because it SHOULD perform better? Thanks for the help. Confused SEO :/, Ricky Shockley

            Schema for Banks and SEO

            I'm researching Schema opportunities for a bank, but besides the shema markup available today (like bankorcreditunion) and developments with FIBO, I can find no answer as to the effect of tagging interest rates and such in terms of SERP/CTR performance or visibility. Does anyone have a case study to share or some insight on the matter?

            Domain prefix changed, will this impact SEO?

            Our web development team have changed our domain prefix from www to non www due to a server change. Our SSL certificate would not be recognised under www and would produce a substantial error message when visiting the secure parts of our website. To prevent issues with old links they have added a permanent 301 redirect from www. to non www. urls until our sitemap catches up. Would this impact our SEO efforts or would it have no impact as a redirect has been placed? Thanks

            SEO value of InDesign pages?

            Hi there, my company is exploring creating an online magazine built with Adobe's InDesign toolset. If we proceeded with this, could we make these pages "as spiderable" as normal html/css webpages? Or are we limited to them being less spiderable, or not at all spiderable?

            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?

            Can you 301 redirect a page to an already existing/old page ?

            If you delete a page (say a sub department/category page on an ecommerce store) should you 301 redirect its url to the nearest equivalent page still on the site or just delete and forget about it ? Generally should you try and 301 redirect any old pages your deleting if you can find suitable page with similar content to redirect to. Wont G consider it weird if you say a page has moved permenantly to such and such an address if that page/address existed before ? I presume its fine since say in the scenario of consolidating departments on your store you want to redirect the department page your going to delete to the existing pages/department you are consolidating old departments products into ?

            Handling 301s: Multiple pages to a single page (consolidation)

            Been scouring the interwebs and haven't found much information on redirecting two serparate pages to a single new page.  Here is what it boils down to: Let's say a website has two pages, both with good page authority of products that are becoming fazed out.  The products, Widget A and Widget B, are still popular search terms, but they are being combined into ONE product, Widget C.  While Widget A and Widget B STILL have plenty to do with Widget C, Widget C is now the new page, the main focus page, and the page you want everyone to see and Google to recognize. Now, do I 301 Widget A and Widget B pages to Widget C, ALTHOUGH Widgets A and B previously had nothing to do with one another?   (Remember, we want to try and keep some of that authority the two page have had.) OR do we keep Widget A and Widget B pages "alive", take them off the main navigation, and then put a "disclaimer" on the pages announcing they are now part of Widget C and link to Widget C? OR Should Widgets A and B page be canonicalized to Widget C? Again, keep in mind, widgets A and B previously were not similar, but NOW they are and result in Widget C. (If you are confused, we can provide a REAL work example of what we are talkinga about, but decided to not be specific to our industry for this.) Appreciate any and all thoughts on this.
