      Hi all,

      So far I have found this one: http://unused-css.com/   It looks like it identifies unused, but perhaps not duplicates? It also has a 5,000 page limit and our site is 8,000+ pages....so we really need something that can handle a site larger than their limit.

      I do have Screaming Frog. Is there a way to use Screaming Frog to locate unused and duplicate CSS?

      Any recommendations and/or tips would be great. I am also aware of the Firefix extensions, but to my knowledge they will only do one page at a time?

      Thanks!

        I read your post at Mstoic Hemant and noticed your comment about Firefox 10. Since I couldn't get Dust-Me Spider to work in my current version of Firefox I tried downloading and installing the older version 10 as you suggested. When I did so, I received the message that the Dust-Me Spider was not compatible with this version of Firefox and it was disabled.

        We are considering purchasing the paid version of Unused CSS (http://unused-css.com/pricing) - Do you have any experience using the upgraded version? Does it deliver what it promises?

        Thanks!

          Hi Hemant,

          I tried using Dust-Me in Firefox, but for some reason it won't work on this sitemap:  http://www.ccisolutions.com/rssfeeds/CCISolutions.xml

          Could it be that this sitemap is too large? I even tried setting up a local folder to store the data, but everytime I try the spider I get the message "The sitemap has no links."

          I am using Firefox 27.0.1

            Hi Dana, did either of these responses help? What did you end up settling on? We'd love an update! Thanks.

              I have an article on that here. An extension for firefox called Dust-Me selectors can help you identify unused CSS on multiple pages. It tracks all the pages you visit of a website and tracks classes and ids which were never used. Moreover, you can also give it a sitemap and it will figure out the CSS which was never used.

                This sounds like it might just do the trick. You'll need to have Ruby installed for it to work. If you have a Mac, it's already on there. If you have a Windows you'll need this. It's pretty easy, I installed Ruby on my Windows gaming rig. If you're running a Linux flavor, try this.

                Just take your URLs from the site crawl and make a txt file. You can compare that with your CSS file. I've never tried it on a large site, let me know how it goes for you.

                  Is having a site map page necessary?

                  Hello all! So I know having a sitemap XML file is important to include in your robots.txt file.  I also know it is important to submit your XML sitemap to Google and Bing.  However, I am wondering if it is beneficial for your site's SEO value to have a sitemap page displayed on your website? Or is this just a redundant action if you have already done the above two actions with your XML sitemap? Thanks in advance!

                  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

                  301 Redirect all pictures when moving to a new site?

                  We have 30,000 pictures on our site. Moz will return 404's on some occasionally, but Google seems to ignore those. Should I 301 redirect all those images when we move to a new site lay-out? Appreciate your views!

                  Fixing Render Blocking Javascript and CSS in the Above-the-fold content

                  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/kempruge/files/kempruge_0.min.css?v=6 http://irp-cdn.multiscreensite.com/…mpruge/files/kempruge_home_0.min.css?v=6 Thanks for any tips, Ruben

                  Old site to new WordPress site - Client concerned about Yahoo Ranking

                  Hello, Back Story I have a client (law firm) who has a large .html website. He has been doing his own SEO for years and it shows. I think the only reason he reached out to a professional is because he got a huge penalty from Google last fall and fell very far down in rankings. Although, he still retains a #1 spot in Yahoo for his site for the keyword phrase he wants. I have been creating a new WordPress theme for the client and creating all new pages and updating the formatting/SEO. From the beginning I have told the client that when we delete the old site and install a new WordPress site (same domain name, but different page hierarchy) he will take a bump in the search engines until all the 301 redirects get sorted out. I told him I can't guarantee any time frame of how long the dip in SEO will last. Some sites bounce right back while others take longer. Last week, during a discussion, he tells me that if he loses his #1 ranking on Yahoo for any length of time he thinks he will go out of business. Needless to say I was a little taken back. When it comes to SEO I use best practice techniques, do my research, stay on top of trends but I never guarantee rankings when moving to a new site. I'm thinking of ways I can help elevate any type of huge SEO drop off and help the client. Here is what I was thinking of suggesting to the client and I would love some feedback. Main Question He has another domain he isn't doing anything with. It's pretty much his domain name with pc added. I was thinking about using that domain to create a simple 1-2 page WordPress website with brand new content (no duplicate content) aimed at attracting his keyword phrase. I would do as much SEO as I could with a 1-2 page site and give it a month or so to see if this smaller site can get into the top #10 in Yahoo, or higher. Then, when we move the site he will still have a website on the first page of Yahoo for his keyword phrase. I hope I explained it clearly 🙂 I would be open to any suggestions anyone may have. Thanks

                  From Google Sites to Wordpress - Anyone Ventured this SEO terrain?

                  We have a few sites in Google Sites - and they are ugly! We have a majority (40+) of websites in Wordpress. But we have a few websites just stuck on Google Sites, and since Google won't let you fully edit the HTML, add scripts, or implement any technology since 2000, we want to move. The sad problem - the Google sites are ranking well. We rank well in Manhattan, Atlanta, Dallas, and Philadelphia. The problem is - the sites do not give much room for growth - and the bounce rate is high because they are so ugly. Has Anyone moved from Google sites to Wordpress? Should we just stay with Google and bite the ugly bullet? My fear is that these sites will not allow for growth. It is hard to update them and even harder to make them look nice. To get a sample - beware: www.counselingphiladelphia.com Even another reason to leave: The slider is non-semantic and terrible SEO. Google won't allow a slider script with tags and a hrefs, so the only way to implement a slider is through a Google Docs Presentation that keeps sliding. I know - terrible SEO (#donthate) but we needed something. Any advice and thoughts would help! Thanks Mozzers!

                  Should the parent directory of the main site-navigation be clickable or not?!?

                  Highly discussed in our team is the question: Should all parent navigation items be clickable, or only the ones that have no child menu appearing on mouse over? At Starwood Germany, we  would like to adjust the main navigation for all our websites in order to improve consistency and user friendliness. At the moment, most of our websites feature both clickable non-clickable parent items, depending on whether the items have a corresponding child menu (appearing on mouse over) or not. See example here: http://www.imperialvienna.com/en Some of our team members believe it might be irritating and/or confusing for the user if some items are clickable while others are not. What do you think? Any thoughts and insights would be truly appreciated!
