          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.

                      Can I safely asume that links between subsites on a subdirectories based multisite will be treated as internal links within a single site by Google?

                      I am building a multisite network based in subdirectories (of the mainsite.com/site1 kind)  where the main site is like a company site, and subsites are focused on brands or projects of that company. There will be links back and forth from the main site and the subsites, as if subsites were just categories or pages within the main site (they are hosted in subfolders of the main domain, after all). Now, Google's John Mueller has said: <<as far="" as="" their="" url="" structure="" is concerned,="" subdirectories="" are="" no="" different="" from="" pages="" and="" subpages="" on="" your="" main="" site.="" google="" will="" do="" its="" best="" to="" identify="" where="" sites="" separate="" using="" but="" the="" is="" same="" for="" a="" single="" site,="" you="" should="" assume="" that="" seo="" purposes,="" network="" be="" treated="" one="">></as> This sounds fine to me, except for the part "Google will do its best to identify where sites are separate", because then, if Google establishes that my multisite structure is actually a collection of different sites, links between subsites and mainsite would be considered backlinks between my own sites, which could be therefore considered a link wheel, that is, a kind of linking structure Google doesn't like. How can I make sure that Google understand my multisite as a unique site? P.S. - The reason I chose this multisite structure, instead of hosting brands in categories of the main site, is that if I use the subdirectories based multisite feature I will be able to map a TLD domain to any of my brands (subsites) whenever I'd choose to give that brand a more distinct profile, as if it really was a different website.

                      Is it against google guidelines to use third party review sites as well as have reviews on my site marked up with schema?

                      So, i look after a site for my family business. We have teamed up with the third party site TrustPilot because we like the way it enables us to send out reviews to our customers directly from our system. It's been going great and some of the reviews have been brilliant. I have used a couple of these reviews on our site and marked them up with: REVIEW CONTENT We work in the service industry and so one of the problems we have found is that getting our customers to actually go online and leave a review. They normally just leave their comments on a job sheet that the workers have signed when they leave. So I have created a page on our site where we post some of the reviews the guys receive too. I have used the following: REVIEW TITLE REVIEW Written by: CUSTOMER NAME Type of Service:House Removal Date published: DATE PUBLISHED 10 / 10 stars I was just wondering I was told that this could be against googles guidelines and as i've seen a bit of a drop in our rankings in the last week or so i'm a little concerned. Is this getting me penalised? Should I not use my reviews referencing the ones on trust pilot and should i not have my own reviews page with rich snippets?

                      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

                      Website Redesign - Will it hurt SERP?

                      Hi - I am planning to redesign my blog and I was wondering if this will affect my rankings? The new website template (custom designed) is much more user and seo friendly. The content, url structure, internal linking structure, meta tags, and site structure will remain exactly the same, but the visual design will be different (new sidebar widgets, and slightly different layout on inner pages). The current website is ranking very well (mostly top 5), has a healthy backlink profile, strong social media presence, and great traffic. I have heard that switching to a new template will dramatically hurt the rankings. Is this true? Are there any exceptions? Any ways I can prevent the rankings from dropping? Would really appreciate your input. Thanks in advance. Howard

                      Seo and CSS media queries

                      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

                      CSS vs Javascript vs JQuery drop down navigation

                      For a user / seo perspective, what is the best way to code a drop down menu nav bar? Is it best to use css, javascript or a scripting library like jquery? I am thinking about overall best practice that will not have a negative impact on serps. I am also thinking about what will work best on all types of devices i.e. desk tops, lap tops, smart phones and tablets. What are the Pro's & Cons of Using CSS for Drop Down Menus. What are the Pro's & cons of using Javascript for drop down menus. And the same question for jquery. Thank you all in advance for your ideas.

                      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!

                      Recommended Website Monitoring Tools

                      Hi, I was wondering what people would recommend for website monitoring (IE is my website working as it should!). I need something that will:
                      1/. Allow multiple page monitoring not just homepage
                      2/. Do header status checking
                      3/. Do page content checking (ie if the page changes massively, or include the word "error") then we have an issue!
                      4/. Multiple alert possibilities. We currently use www.websitepulse.com and it is a good service that does all the above, however it just seems so overly complex that its hard to understand what is going on, and its complex functionality and features are really a negative in our case. Thanks
