EDIT: The error appears to be fixed, but The Verge never replied to any of my attempts to contact them about this. Hopefully they fixed it in time.



Popular online news website The Verge announced via social media today that they were merging their mobile and tablet versions of the site into a new, responsive version of the website. Typically when large moves like this are made errors are committed I was curious if a large site like the Verge had properly tested their URL structure for SEO and UX before finalizing the merger or, if like so many others, they missed something.

Please note, I’ve done my best to notify The Verge about this error so hopefully they clear it up soon. I’m only writing this quick blog post as a warning to others who might want to move URLsURL other versions: Uniform Resource Locator noun A string o... More or launch a new version of their site.



Previously to their new, responsive, version of the site The Verge appears to have used 2 sets of URLs. They had their main, pc and laptop friendly, site located on http://www.TheVerge.com and they had their mobile site located at http://mobile.TheVerge.com other than the subdomain being different the URL structures for pages were the same. So for example the page /2012/3/29/2910536/google-investigating-play-store-error was found on both domains and still appears on the WWW (main) version of the site.

Before a site is launched an SEO should use a tool to check what code is being reported from the old domain when seen by bot. These tools are called “Server Header Checkers” and SEOBook.com has a good one here you can use. If The Verge had done their redirects properly they might have done a 1 to 1 redirect from each MOBILE URL to the same URL on WWW. This is known as URL mapping and can be a bit tedious especially for a site the size of The Verge. There are other solutions for large sites based on Apache such as using REGEX code (Regular Expressions) inside of an HTACCESS file to create rules to direct each URL over which in this case would have been fairly simple since the only thing changing was the subdomain. Either way it’s a pretty easy redirect to make and even a novice programmer would be able to build it and have it up and running in a days work or two.

So running a few of the mobile URLs through the above mentioned Server Header Checker tool it appeared that the 301 redirects were indeed being handled properly. Each MOBILE version returned a server status code of 301 Permanently Moved to the corresponding WWW URL. I tried this with several pages I found by doing a search on Google and Bing for “site:mobile.theverge.com” and made sure to include the main URL, categories, and story URLs. All seemed to be a go, but when checking to ensure that URLs are being handled correctly merely pasting a URL into a checker tool ins’t enough. Bots don’t copy and paste URLs to assign link juice, they follow them via other websites. A very important distinction that could cause problems.

I used MOZ’s OpenSiteExplorer to find pages that linked to documents on the MOBILE version of the site and then clicked those links. This is what uncovered the SEO Fail made by The Verge. Every single MOBILE url, when clicked from a referring site, is redirected to the WWW HOMEPAGE. This is a big problem from an SEO and UX standpoint. First off users will get redirected to a home page that makes it incredibly difficult to find older documents and is designed to funnel trafficTraffic other versions: web traffic noun General term for vi... More to new, fresh content. Secondly a search bot is getting a different server status code when they follow these links that is a 301 Permanently Moved code to the WWW HOMEPAGE (i.e. http://www.TheVerge.com)

The net result for The Verge will be a very quick drop in search rankings for all of the longtail stuff their old news stories ranked on, this will also directly impact their advertising revenue and could cause other unforseen issues. It’s never enough to merely click a link or pass a link through a server header checker tool. You must do both on numerous URLs when making a site move or a URL merger like this to ensure that everything is being handled properly for both the sake of users and bots.
