Subdomains vs. Subfolders, Rel Canonical vs. 301, and How to Structure Links for SEO - Whiteboard Friday - Moz Blog |
| Posted on: Friday 06 February 2015 — 01:18 Posted by randfish There are some basic questions about SEO that come up really frequently, and it's often easy to assume an answer that isn't exactly right. In today's Whiteboard Friday, Rand tackles three of them:
For reference, here's a still of this week's whiteboard! Video transcriptionHowdy, Moz fans, and welcome to another edition of Whiteboard Friday. This week we're going to chat about structuring content, placing content, and placing links, specifically with regards to some things that have come up over and over again in the SEO world, but still seem to be a challenge for many of us who play in the field. One of the questions that I'm going to start with is around subdomains and subfolders, because this just comes up again and again and again. I think one of the reasons it's emerged in the last few years is, unfortunately, some statements by Googlers themselves -- a statement a few years ago from Matt Cutts, and one, I think last year or two years ago, from John Mueller basically saying, "Hey, Google has gotten much better at identifying and associating content that's on a subdomain with the main domain, and you don't need to worry about placing content on two separate subdomains anymore." I am sure that Google has actually made strides in this area, but this question still has the same answer that it did years ago. I'll show you some examples. You're asking, "Should I put my content on a subdomain, or should I put it in a subfolder?" Subdomains can be kind of interesting sometimes because there's a lot less technical hurdles a lot of the time. You don't need to get your engineering staff or development staff involved in putting those on there. From a technical operations perspective, some things might be easier, but from an SEO perspective this can be very dangerous. I'll show you what I mean. So let's say you've got blog.yoursite.com or you've got www.yoursite.com/blog. Now engines may indeed consider content that's on this separate subdomain to be the same as the content that's on here, and so all of the links, all of the user and usage data signals, all of the ranking signals as an entirety that point here may benefit this site as well as benefiting this subdomain. The keyword there is "may." I can't tell you how many times we've seen and we've actually tested ourselves by first putting content on a subdomain and then moving it back over to the main domain with Moz. We've done that three times over that past two years. Each time we've seen a considerable boost in rankings and in search traffic, both long tail and head of the demand curve to these, and we're not alone. Many others have seen it, particularly in the startup world, where it's very popular to put blog.yourwebsite.com, and then eventually people move it over to a subfolder, and they see ranking benefits. But even more telling was a recent example from just a few months ago on the iwantmyname blog. Timo Reitnauer wrote on the iwantmyname blog a piece about how he had moved their content actually from the main domain to a subdomain, which is not usually the way we see things going. But, man, when that happened, ugly, super, super ugly. You can see his traffic graph. He graphed his Google search traffic and showed, from his Google Analytics, a nice snapshot of when they made the move, what happened to their search traffic, how long it took to recover. It actually still hasn't recovered. It's been five or six months now. So very, very frustrating for them, and they're going to move it back over. I think maybe they already have moved it back over. But this was great in that this piece went to the front of Hacker News. Lots of folks from around the startup and technology worlds commented on it, shared their experiences and opinions as well. Bottom line is it's really dangerous to put content on a subdomain still. I believe John and I believe Matt when they say that Google has made strides in this direction. The problem is they're not good enough or perfect enough to rely on that factor, and so I'd really urge everyone to keep your content on one single sub and root domain, preferably in subfolders. That's how you're going to maximize your potential SEO benefit. This is one of those technical SEO things that just hasn't changed for many years now. Next up, a question around rel=canonical, and 301s, especially cross-domain rel=canonical, meaning people are pretty comfortable with the rel=canonical that sits on your own website on your pages and maybe says, "Hey, the print version of this page should actually be considered the same as the web version of this page. Or the mobile version of this page should be considered the same as the regular version." That's fine. But folks have more questions when it comes to cross-domain rel=canonicals and content that perhaps they own because they own multiple websites, or they have licensing agreements across those, or they have business development or partnerships, those kind of things. So they're wondering, "Hey, I've got content on multiple websites, and I want to move some of that content, or I want engines to interpret it all as coming from my site. Should I put it on the other website and use a 301 to redirect it, or should I use a cross-domain rel=canonical to say the old page is now the new page?" Well, actually this is one where, from a technical perspective, the engines are doing a pretty darn solid job. Google is doing a very good job. We've seen Bing make strides here with cross-domain rel=canonical. They seem to be doing a pretty good job as well. I haven't tested them as intensely though recently. Basic story is with the 301, other site.com/a can redirect to your site.com/a, and both visitors and engines, anyone requesting the old page, get the new page. The only difference with the rel=canonical is that when a visitor requests the old page, they're still going to get it. They're still going to get that othersite.com/b. Search engines, however, are going to get the new version of the page, or they're essentially going to consider these to be one and the same. What we've seen is that, in both of these cases, the ranking signals seem to be passed very similarly, if not perfectly similarly, very similarly. It's hard to detect any difference there. But the rel=canonical can give you an option whereby you say, "Hey, I want to maintain the branding or some unique aspect of something that happens around othersite.com, and so I wish that I could have visitors be able to still go to that page, but have search engines know, hey this is actually just a copied version of this one, and if you're going to rank one of these two, I'd prefer you to rank this one." That's a great use for the cross-domain rel=canonical. But this is much more a user experience and a branding experience issue than it is a technical SEO one, because both of these work pretty darn well. Then the last issue I'll cover today are around some of this content and link optimization stuff is: What if you've got multiple websites all linking back to your main site, and you're wondering does that or would that help my SEO? I can't tell you how many folks, surprisingly even folks who are very savvy, who have done lots of other stuff in the technical and web development worlds, are thinking about this from a SEO perspective. I can understand where it comes from. Basically, you have this understanding that more links is a good thing and that more link diversity is a good thing. So you think to yourself, "Hey, maybe I can capture more links and more link diversity by having more slightly different websites. I want to keep my main site all about one particular topic or one particular niche of that topic, and I want to have these other niche sites that maybe I have some great domain names in my portfolio or some really brandable ones. Maybe I've picked up some old domain names that I've bought, or I've bought entire properties outright. So what I'm going to do is I'm just going to add a site-wide link or many links from these pages all back over to my main site." What you're hoping is that this will amplify your ranking signals and amplify your opportunity. The opposite is true. In fact, what's happening is you're creating a barrier for the full link equity for brand, user and usage data signals, and any potential social signals. You're creating a barrier that's stopping some of those things from passing fully here. Let's just imagine that you've got four links over here, and they are all pointing to mysubsite1.com, which you're then thinking, "That's great. That's exactly what I wanted to have happen, and now mysubsite1 is pointing to my main site." You're actually losing most of the link equity, the value, the ranking power that would be passed if only two or three of these links had linked directly over to your main site. As we talked about with the subdomain/subfolder issue, by collecting all of the ranking signals on one sub and root domain, you create the best possible benefit. This concept of domain authority -- I don't necessarily mean the number in Moz's Mozscape Index -- the concept of domain authority is that basically as a domain becomes more popular, as it inherits all of these ranking signals, could come from links, from visibility, from branding, user and usage data, all the kinds of signals that a domain inherits, it passes those on to all of its different pages. But it doesn't pass them on to other sites. That's true for each of these as well. They're inheriting signals that they're not fully passing on here. I'd recommend that you 301 redirect all of these and have one main site. It simplifies a bunch of your work and streamlines it. It lets you focus on building this one brand. Branding is so powerful today and online visibility as a whole, not to mention SEO, that this is really a best practice. I would get rid of those subsites as best you can. There are still reasons sometimes to have a microsite or a different website for branding purposes, or if you're going to sell that site separately, or if it's a completely different team working on it. But from an SEO perspective, everything on one sub and root is really ideal. All right everyone, look forward to the comments, and we will see you again next week for another edition of Whiteboard Friday. Take care.

| Enhanced Reporting Now Available in Moz Local Posted on: Thursday 05 February 2015 — 12:30 Posted by David-Mihm As we approach Moz Local's first birthday—just over six weeks away—I'm excited to share with you our second major feature release since launch! For those of you who are already managing your local search listings through Moz Local, this feature is available as of today for all accounts. For those of you who aren't yet customers, we hope this release provides a few more reasons to sign up (if you're curious to see what it looks like, you can check your local listing for free). Read on for more detailed information about what we're releasing and why we're so excited about these new features. New Dashboard MetricsListing ReachObviously local search is an incredibly complex discipline, and one of the hardest things for non-experts to understand (most of your clients and bosses, I'm guessing?) is the dramatic impact that the primary aggregators can have on the health and visibility of your listings. We hope that this metric helps explain the value of the data aggregators via Moz Local. Listing Reach is our indirect representation of how far the data aggregators have spread your listings across the local ecosystem, based on the number of results returned for exact-match searches of your NAP. For more information about this metric, head on over to our Help Hub. Percentage accuracy on each site in the Moz Local network While these metrics have always been available at the individual location level (and will continue to be), you can now view them right from your dashboard, and New Reporting FeaturesMetrics across multiple listings Percentage accuracy is not the only metric that's available across multiple listings; average score and aggregate listing reach are also enabled by default for whatever locations are in view on your dashboard. Labeling of listingsIf you're managing multiple clients, or work at a large brand with multiple locations, though, you probably want to pick and choose the ones whose metrics you want to roll-up. You can now add labels to each listing that you manage, for easy slicing and dicing. Our labels work similarly to Gmail, which we hope will make them intuitive to use. Once you add one or more labels, they'll start to appear as presets within your sidebar. Naming conventions are totally flexible, so you can segment your locations however you'd like. You're just one click away from a roll-up report for all locations with a given label. Enhanced search operators To make the job of labeling locations easier for you, we've also added some additional search operators to make your lives easier. The full list of supported operators is below:
You can use these operators to pull up instantly any location you're managing (and of course, view metrics for that specific listing). Metrics over timeTwo metrics are also now visible over time: average score and aggregate listing reach. One of the primary requests we've heard from agency owners and practitioners over the last several months is the need to demonstrate the value of your efforts to your clients, and we hope that graphs like the one below will help you do just that. In September 2014, you may notice a stairstep in the shaded area at the bottom of the report, and a corresponding dip in the line graph above. The shaded area represents total locations under management in a given month. Our goal in showing your metrics over time in the context of the number of managed locations is to explain anomalies in the graph like the dip above. In my specific case, I added a mortgage broker friend's location in September who was just getting started with his Local SEO campaign—meaning his Listing Score was literally 0 prior to starting with Moz Local. Those of you who phase in clients over time will likely see similar anomalies in your line graphs, so we hope that this representation helps prevent unnecessary panicking :). Upcoming EnhancementsWe're definitely not stopping here.Later this spring, we'll be rolling out the ability to export metrics from your dashboard for use in your own Excel reports, a PDF report generation feature, and a more streamlined Foursquare validation process, among other improvements. We're growing our engineering team rapidly and will release these as soon as we can! Check It Out for YourselfAs I said in the intro, this feature is available for all existing customers today, so just head on over to your dashboard. And if you're not yet a customer, we hope you soon will be. Along with yours truly, fellow Mozzers from our product, engineering and account teams will be available for demos throughout the day on Saturday at #LocalUp, so don't be a stranger. We're looking forward to speaking with many of you in Seattle!
