      We don't have a responsive design site yet, and our mobile site is built through Dudamobile. I know it's not the best, but I'm trying to do whatever we can until we get around to redesigning it. Is there anything I can do about the following Page Speed Insight errors or are they just a function of using Dudamobile?

      Eliminate render-blocking JavaScript and CSS in above-the-fold content

      Your page has 3 blocking script resources and 5 blocking CSS resources. This causes a delay in rendering your page.None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.Remove render-blocking JavaScript:

      • http://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js
      • http://mobile.dudamobile.com/…ckage.min.js?version=2015-04-02T13:36:04
      • http://mobile.dudamobile.com/…pts/blogs.js?version=2015-04-02T13:36:04

      Optimize CSS Delivery of the following:

      • http://fonts.googleapis.com/…:400|Great+Vibes|Signika:400,300,600,700
      • http://mobile.dudamobile.com/…ont-pack.css?version=2015-04-02T13:36:04
      • http://mobile.dudamobile.com/…kage.min.css?version=2015-04-02T13:36:04

      • http://irp-cdn.multiscreensite.com/…mpruge/files/kempruge_home_0.min.css?v=6

      Thanks for any tips,

      Ruben

            there is not a very easy way to modify HTML on WordPress because it is all based on PHP. Unless you can change the PHP code via by FTP or many other methods including plug-ins it takes a developer.

            http://www.gregreindel.com

            I know a person who could fix this for you very easily there contact information is in the URL under contact. There are also some plug-ins that will eliminate this

            https://wordpress.org/plugins/async-js-and-css/screenshots/

            the best methods in my opinion are done by a developer or sometimes a plug-in

              with

              http://www.feedthebot.com/tools/css/ (for CSS)

              this for JS

              http://www.jsmini.com/

                Actually, I have a quick follow up. In my wp-admin in the editor section, I only see CSS and PHP files. Then, on the ftp, I see a public_html folder, but that folder has a ton of different files in it...none of which end in html. Any suggestions on where this html file might live?

                Thanks,

                Ruben

                  I will take a look at it. Yes, I do need to do it on our Wordpress site as well, but fortunately, Page Speed Insights doesn't think our desktop version is as abysmal as our mobile one. But, it does still show up as something that should be fixed.

                  Thanks for the reference material!

                    you will also need to find your Cardinal path and simply combine JavaScript and CSS as well as prioritize content that is above the fold. By doing so this will help you to create one JS file ( possibly more if it is impossible to combine for whatever reason)

                    See more here

                    I really hope this helps,

                      Hi Ruben,

                      Here is a tutorial on how to fix that issue. If I could explain it better than this I would however I feel this does a fantastic job if you're doing this on WordPress let me know and I will tell you how to fix it on there is well.

                      Here's the resource

                      http://www.feedthebot.com/pagespeed/render-blocking.html

                      http://www.feedthebot.com/pagespeed/defer-loading-javascript.html

                      The below code is what Google recommends. This code should be placed in your HTML just before the tag (near the bottom of your HTML file). I highlighted the name of the external JS file.

                      sincerely,

                      Thomas

                        How to fix non-crawlable pages affected by CSS modals?

                        I stumbled across something new when doing a site audit in SEMRUSH today ---> Modals. The case: Several pages could not be crawled because of (modal:) in the URL. What I know: "A modal is a dialog box/popup window that is displayed on top of the current page" based on CSS and JS. What I don't know: How to prevent crawlers from finding them.

                        Should i be using shortcodes for my my page content.

                        Hello, I have a question. Sorry if this is been answered before. Recently I decided to do a little face lift to my main website pages. I wanted to make my testimonials more pretty. Found this great plugin for testimonials which creates shortcodes. I love how it looks like, but just realised that when I use images in shortcodes, these are not picked up by search engines 😞 only text is. Image search ability is pretty important for me and I'm not sure if I should stick with my plain design and upload images manually with all alt tags and title tags or there is a way to adjust shortcode so it shows images to search engines. You can see example here. https://a-fotografy.co.uk/maternity-photographer-edinburgh/ Let me know your thoughts guys. Regards, Armands

                        Hiding content until user scrolls - Will Google penalize me?

                        I've used: "opacity:0;" to hide sections of my content, which are triggered to show (using Javascript) once the user scrolls over these sections. I remember reading a while back that Google essentially ignores content which is hidden from your page (it mentioned they don't index it, so it's close to impossible to rank for it). Is this still the case? Thanks, Sam

                        Duplicate content on websites for multiple countries

                        I have a client who has a website for their U.S. based customers. They are currently adding a Canadian dealer and would like a second website with much of the same info as their current website, but with Canadian contact info etc. What is the best way to do this without creating duplicate content that will get us penalized? If we create a website at ABCcompany.com and ABCCompany.ca or something like that, will that get us around the duplicate content penalty?

                        Hello to all participants! I'm starting on responsive design with css media queries and I was wondering if hidding content can, in this case, can also be bad for seo? I know that hidding content is bad (eg. display: none;), but is it also like that with responsive design or does Google see it other way? If I have a news column with title, image and text for 1024px and hide the text and image leaving just the title for 768px, or smaller, will Google consider this black hat and will it be bad for seo? are there any articles I can read about this subject, and other similar subjects? sorry for my english 🙂 thanks
