      Although Google and Bing have recommended that the same URL be used for serving desktop and mobile websites, portals like airbnb are using different URLS to serve mobile and web users.

      Does anyone know why this is being done even though it is not GOOD for SEO?

        Its often a case of logistics in updating a site to be responsive design, the only way the same URL can serve dynamic content to mobile and desktop devices. Previously many sites have had to create alternate mobile sites.

        So while responsive is now the recomended approach, many sites still use subdomains or directorys. This useful post also casts light on when these multiple methods are most suitable. When Responsive Design is not an option.

        Hope this helps.

          Some sites serve different content to mobile devices, therefore require a seperate URL.

          Google and Bing currently prefer responsive design because it allows the same URL to be displayed on desktop and mobile devices and requires less crawling ./ indexing on their behalf.

            Do content copycats (plagiarism) hurt original website rankings?

            Hi all, Found some websites stolen our content and using the same sentences in their website pages.  Does this content hurt our website rankings?  Their DA is low, still we are worried about the damage about this plagiarism. Thanks

            I show different versions of the same page to the crawlers and users, but do not want to do anymore

            Hello, While Google could not read JavaScript, I created two versions of the same page, one of them is for human and another is for Google. Now I do not want to serve different content to the search engine. But, I am worry if I will lose my traffic value. What is the best way to succeed it without loss? Can you help me?

            Hosting Multiple Websites Within The Same Server Space

            Hi, So, I have a client who wants to host two websites (which you could refer to as sister sites) on the same hosting account. For some reason, I was under the impression that doing as much may be detrimental (for SEO purposes). Am I correct in thinking this? Can I get some back-up documentation or comments here? I look forward to hearing what you all have to say. Thanks for reading!

            Site Footer Links Used for Keyword Spam

            I was on the phone with a proposed web relaunch firm for one of my clients listening to them talk about their deep SEO knowledge. I cannot believe that this wouldn’t be considered black-hat or at least very Spammy in which case a client could be in trouble. On this vendor’s site I notice that they stack the footer site map with about 50 links that are basically keywords they are trying to rank for. But here’s the kicker shown by way of example from one of the themes in the footer: 9 footer links:
            Top PR Firms
            Best PR Firms
            Leading PR Firms
            CyberSecurity PR Firms
            Cyber Security PR Firms
            Technology PR Firms
            PR Firm
            Government PR Firms
            Public Sector PR Firms Each link goes to a unique URL that is basically a knock-off of the homepage with a few words or at the most one sentences swapped out to include this footer link keyword phrase, sometimes there is a different title attribute but generally they are a close match to each other. The canonical for each page links back to itself. I simply can’t believe Google doesn’t consider this Spammy. Interested in your view.

            Should You Link Back from Client's Website?

            We had a discussion in the office today, about if it can help or hurt you to link back to your site from one that you optimize, host, or manage. A few ideas that were mentioned: HURT:
            1. The website is not directly related to your niche, therefore Google will treat it as a link exchange or spammy link.
            2. Links back to you are often not surrounded by related text about your services, and looks out of place to users and Search Engines. HELP:
            1. On good (higher PR, reputable domain) domains, a link back can add authority, even if the site is not directly related to your services.
            2. Allows high ranking sites to show users who the provider is, potentially creating a new client, and a followed incoming link on anchor text you can choose. So, what do you think? Test results would be appreciated, as we are trying to get real data. Benefits and cons if you have an opinion.

            Why website isn't showing on results?

            Hello Moz! Just got a quick question - we have a clientcalled and for some reason they just aren't showing up in the search results. It's not a new domain and hasn't been penalised (or has reason for penalty). All the content is fresh and has no bad back links to the site. It is a new website and has been indexed by Google but for even for branded search terms, it just doesn't show up anywhere on page 1 (i think page 4). Any help or advise is great appreciated is it's doing my head in. We are using www.google.com.au. Kindest Regards

            href="#" and href="javascript.void()" links. Is there a difference SEO wise?

            I am currently working a site re-design and we are looking at if href="#" and href="javascript.void()" have an impact on the site? We were initially looking at getting the links per page down but I am thinking that rel=nofollow is the best method for this. Anyone had any experience with this? Thanks in advanced
