          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

                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

                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

                How Does Dynamic Content for a Specific URL Impact SEO?

                Example URL:  http://www.sja.ca/English/Community-Services/Pages/Therapy Dog Services/default.aspx The above page is generated dynamically depending on what province the visitor visits from.  For example, a visitor from BC would see something quite different than a visitor from Nova Scotia; the intent is that the information shown should be relevant to the user of that province. How does this effect SEO?  How (or from what location) does Googlebot decide to crawl the page? I have considered a subdirectory for each province, though that comes with its challenges as well.  One such challenge is duplicate content when different provinces may have the same information for some pages.  Any suggestions for this?

                Can you noindex a page, but still index an image on that page?

                If a blog is centered around visual images, and we have specific pages with high quality content that we plan to index and drive our traffic, but we have many pages with our images...what is the best way to go about getting these images indexed? We want to noindex all the pages with just images because they are thin content... Can you noindex,follow a page, but still index the images on that page? Please explain how to go about this concept.....

                Page titles in browser not matching WP page title

                I have an issue with a few page titles not matching the title I have In WordPress.  I have 2 pages, blog & creative gallery, that show the homepage title, which is causing duplicate title errors.  This has been going on for 5 weeks, so its not an a crawl issue.  Any ideas what could cause this? To clarify, I have the page title set in WP, and I checked "Disable PSP title format on this page/post:"...but this page is still showing the homepage title.  Is there an additional title setting for a page in WP?

                Splitting Page Authority with two URLs for the same page.

                Hello guys, My website is currently holding two different URLs for the same page and I am under the impression such set up is dividing my Page Authority and Link Juice. We currently have the following page with both URLs below: www.wbresearch.com/soldiertechnologyusa/home.aspx
                www.wbresearch.com/soldiertechnologyusa/ Analysing the page authority and backlinks I identified that we are splitting the amount of backlinks (links from sites, social media and therefore authority). "/home.aspx"
                PA: 67
                Linking Root Domains: 52
                Total Links: 272 "/"
                PA: 64
                Linking Root Domains: 29
                Total Links: 128 I am under the impression that if the URLs were the same we would maximise our backlinks and therefore page authority. My Question: How can I fix this? Should I have a 301 redirect from the page "/" to the "/home.aspx" therefore passing the authority and link juice of “/” directly to “/homes.aspx”? Trying to gather thoughts and ideas on this, suggestions are much appreciated? Thanks!

                How much impact does bad html coding really have on SEO?

                My client has a site that we are trying to optimise. However the code is really pretty bad. There are 205 errors showing when W3C validating. The >title>, , <keywords> tags are appearing twice. There is truly excessive javascript. And everything has been put in tables.</keywords> How much do you think this is really impacting the opportunity to rank? There has been quite a bit of discussion recently along the lines of is on-page SEO impacting anymore. I just want to be sure before I recommend a whole heap of code changes that could cost her a lot - especially if the impact/return could be miniscule. Should it all be cleaned up? Many thanks

                What's the SEO impact of url suffixes?

                Is there an advantage/disadvantage to adding an .html suffix to urls in a CMS like WordPress. Plugins exist to do it, but it seems better for the user to leave it off. What do search engines prefer?
