    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.

                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.

                Incorporating Spanish Page/Site

                We bought an exact match domain (in Spanish) to incorporate with regular website for a particular keyword. This is our first attempt at this, and while we do have Spanish speaking staff that will translate/create a nice, quality page, we're not going to redo everything in Spanish page. Any advice on how to implement this? Do I need to create a whole other website in Spanish? Will that be duplicate content if I do? Can I just set it up to show the first page in Spanish, but if they click on anything else it redirects to our site? I'm pretty clueless on this, so if anything I've suggested is off-the-wall or a violation, I'm really just spit-balling, trying to figure out how to implement this. Thanks, Ruben

                Duplicate Content Issue: Mobile vs. Desktop View

                Setting aside my personal issue with Google's favoritism for Responsive websites, which I believe doesn't always provide the best user experience, I have a question regarding duplicate content... I created a section of a Wordpress web page (using Visual Composer) that shows differently on mobile than it does on desktop view. This section has the same content for both views, but is formatted differently to give a better user experience on mobile devices. I did this by creating two different text elements, formatted differently, but containing the same content. The problem is that both sections appear in the source code of the page. According to Google, does that mean I have duplicate content on this page?

                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

                Can external links in a menu attract a penalty?

                We have some instances of external links (i.e. pointing to another domain) in site menus. Although there are legitimate reasons (e.g. linking to a news archive kept on a separate domain) I understand this can be considered bad from a usability perspective. This begs the question - is this bad for SEO? With the recent panda changes we've seen certain issues which were previously "only" about usability attract SEO penalties, but I can't find any references to this example. Anyone have thoughts / experience?

                Will google penalize a website for using a table layout?

                I just got a new client today and his entire website layout and structure is using tables instead of divs. This client is on a tight budget and wants to avoid unnecessary hours for re-coding the website, but at the same time he wants me to improve his SEO organically. This is the first time I've been asked to do work on an existing website that uses pure tables for the entire layout and I'm wondering if this effects the SEO in any way. So my question is, will tables effect rankings and SEO in any way?

                Separate .mobi site or make .com site mobile friendly?

                Our website now has enough mobile traffic to justify going mobile friendly, which it is not at this time. I am in favor of making a separate .mobi site designed specifically for mobile phones and smart phones for several reasons. It is cheaper, faster, and easier to accomplish. I think our mobile users will have a good experience though obviously not as much info as our full site. I would use ourdomain.mobi with link or a redirect for mobile users from from the main site. My top three choices for implementing that are http://allwebcodesign.com/setup/mobi-templates.htm#detailsarea
                Template that can be viewed by mobile or desktop. http://www.onbile.com/ http://www.networksolutions.com/mobile-website/index.jsp Does this seem like a good solution?

                Site-wide footer links or single "website credits" page?

                I see that you have already answered this question before back in 2007 (http://www.seomoz.org/qa/view/2163), but wanted to ask your current opinion on the same question: Should I add a site-wide footer link to my client websites pointing to my website, or should I create a "website credits" page on my clients site, add this to the footer and then link from within this page out to my website?
