      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.

            What if i dont use an H1, but rather, h2 with multiple keywords.

            the reason i dont want to use h1 is because i can have only one h1, however if i use several h2s. is it gonna help me rank? bacause google likes h1 more than h2, is google gonna give more priority or same priority to h2., and if that priority is gonna be less, what will be the percentage of that lessness? for ex: h1 gets 90 score if my h1 is missing how much score my h2 will get out of hundred(i know there is no such metric but i am just wondering anyways)

            What to do with internal spam url's google indexed?

            I am in SEO for years but never met this problem. I have client who's web page was hacked and there was posted many, hundreds of links, These links has been indexed by google. Actually these links are not in comments but normal external urls's. See picture. What is the best way to remove them? use google disavow tool or just redirect them to some page? The web page is new, but ranks good on google and has domain authority 24. I think that these spam url's improved rankings too 🙂 What would be the best strategy to solve this. Thanks. k9Bviox

            Does Google and Other Search Engine crawl meta tags if we call it using react .js ?

            We have a site which is having only one url and all other pages are its components. not different pages. Whichever pages we click it will open show that with react .js . Meta title and meta description also will change accordingly. Will it be good or bad for SEO for using this "react .js" ?

            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.

            Vanity URLs Canonicalization

            Hi, So right now my vanity URLs have a lot more links than my regular homepage. They 301 redirect to the homepage but I'm thinking of canonicalizing the homepage, as well as the mobile page, to the vanity URL. Currently some of my sites have a vanity URL in a SERP and some do not. This is my way of nudging google to list them all as vanity but thought I would get everyone's opinion first. Thanks!

            Advice needed! How to clear a website of a Wordpress Spam Link Injection Google penalty?

            Hi Guys, I am currently working on website that has been penalised by Google for a spam link injection.  The website was hacked and 17,000 hidden links were injected. All the links have been removed and the site has subsequently been redesigned and re-built.  That was the easy part 🙂 The problems comes when I look on Webmaster.  Google is showing 1000's of internal spam links to the homepage and other pages within the site.  These pages do not actually exist as they were cleared along with all the other spam links. I do believe though this is causing problems with the websites rankings.  Certain pages are not ranking on Google and the homepage keyword rankings are fluctuating massively. I have reviewed the website's external links and these are all fine. Does anyone have any experience of this and can provide any recommendations / advice for clearing the site from Google penalty? Thanks, Duncan

            Footer Link in International Parent Company Websites Causing Penalty?

            Still waiting to look at the analytics for the timeframe, but we do know that the top keyword dropped on or about April 23, 2012 from the #1 ranking in Google - something they had held for years, and traffic dropped over 15% that month and further slips since. Just looked at Google Webmaster Tools and see over 2.3MM backlinks from "sister" compainies from their footers.  One has over 700,000, the rest about 50,000 on average and all going to the home page, and all using the same anchor text, which is both a branded keyword, as well as a generic keyword, the same one they ranked #1 for. They are all "nofollows" but we are trying to confirm if the nofollow was before or after they got hit, but regardless, Google has found them. To also add, most of sites are from their international sites, so .de, .pl, .es, .nl and other Eurpean country extensions. Of course based on this, I would assume the footer links and timing, was result of the Penguin update and spam. The one issue, is that the other US "sister" companies listed in the same footer, did not see a drop, in fact some had increase traffic.  And one of them has the same issue with the brand name, where it is both a brand name and a generic keyword.  The only note that I will make about any of the other domains is that they do not drive the traffic this one used to. There is at least a 100,000+ visitor difference among the main site, and this additional sister sites also listed in the footer. I think I'm on the right track with the footer links, even though the other sites that have the same footer links do not seem to be suffering as much, but wanted to see if anyone else had a different opinion or theory. Thanks!
