Domain Authority
-
I made some changes to my site and many of my keywords improved dramatically. Its odd however, that the changes caused the domain authority to go down by 3 points, from 20 to 17. Is this a short term thing caused by recent changes and likely to recover?

Moz's index isn't a complete view of the web, but we try to crawl quality sites out there. Our index is always growing. But to be frank, no one -- not even Google -- crawls the entire web. There are just too many pages out there and computing power is expensive. Google crawls the most links simply because Google is a bigger company with more money and more servers and more engineers and who's business depends on serving web pages to everyone.
At Moz, we focus on quality sites because we believe (and hope) our customers and community are focusing on high quality links that are still active, which are going to give them the best SEO results. (Also a huge part of the web is just spam nonsense.) Many SEOs -- and I include myself here -- will use multiple sources of link indexing for the broadest view of the web and their sites. I use Moz's OSE and Google Webmaster Tools (free and big, but includes lots of spam, which can be great if you're fighting a Penguin penalty). Others will use OSE, GWT, and OSE competitors like Majestic and Ahrefs, especially if link building is huge for them and they want to account for every penny. Every index is a bit different.

Yes, it looks like MOZ shows fewer inbound links. But, Google shows I have increased inbound links. Actually, there is a large difference as what MOZ and Google see. Why is that?

Mine dropped 3 points too
But I feel slightly better now knowing i'm not the only one. #Smallheartattack -
It is due to latest Mozscape index on 22nd of June, this has result in drop in DA and PA. I also believe the index include fewer links or url which leads to this drop.it is likely, you've built additional quality/relevant links as you have mentioned, but with the smaller Index these new links, and even previously indexed links, are not being picked up. Therefore, less links are being used to calculate your domain authority score. I would say the drop in your Domain Authority is due to the size of the index.

.com vs .co.uk domain
I have a client who has a site live at example**.co.uk** and would like to rank for the term "example". But example**.com** is owned by another company who offers a different product and service and has been live since 2003. I know that I can make example**.co.uk** rank for keywords related to their service but I think it's going to be a struggle to get them to rank for the brand term "example" as the .com site already owns Page 1 with their domain name, Facebook page, Wiki page etc etc. The only variation is that example**.com** is a US based company and my client want to ranks in the UK only. What are the chances I can out rank example**.com** for the brand term on www.google.co.uk if example**.com** currently owns Page 1 on google**.co.uk**?

Domain authority, moztrust, mozrank have been dropping. 2. We had 368k links on 6/27 and on 7/11 we had 563k Is this a result of confusion between our www.websitenamehere.com and websitenamehere.com?

Using rel="author" on product descriptions
Unique and effective product descriptions can be one of the most expensive investments that go into building a retail website. I would consider them part of the "intellectual property" of a company. These descriptions are also one of the most often pirated types of content. Some product descriptions have been grabbed and used by hundreds of pirates. When people grab your product descriptions it creates a duplicate content problem, it also starts cutting off your long-tail traffic. The discussion topic here is.... Have you heard of anyone using rel="author" on product pages with substantive content? Do you think there is any value in doing that? Is this an abuse of rel="author" Thank you!

Negatives to using custom sub domain?
So - being photographers, we have our main website, but also, we use a hosted service for all our client galleries (www.zenfolio.com) So, in effect, we have two websites: Our main informational website Our client gallery/proofing website The client gallery has back links to our main website - so, when people are viewing their gallery, they can easily get back to our main site. We also have thrown a few of our preferred keywords in there for SEO purposes. The gallery has thousands of pages which link back to the main site. So.. the client gallery URL can either be: http://ourbusinessname.zenfolio.com OR we can have it so it uses our own domain, such as: http://gallery.ourbusinessname.com The question is, which domain name will benefit the back links more? Our custom subdomain (which links to our main domain) or, using the Zenfolio domain (which is external to our site). Or, is there no real difference either way? Or.. do I make no sense?

Does Google give any (negative) weight to .info domains?
Hi, All! We're working with a client on setting up a support blog for their site (not hosted on-site because it's a related topic, not directly about their business). We're thinking about a few domain possibilities, but for some of the ones we'd like the .com is already taken. .info (as well as others) are available, and the client is interested in using a different TLD, but I'm shying away from it because of the concern that: a) people will look at it more suspiciously (exactmatch.info? must be spam) - but maybe that's just because I'm an SEO b) does Google have anything against exact match domains with endings like .info, .net, etc.? (I know there's never any guarantee that the exact match domain will continue to hold its weight in the algorithm at all, but taking that as a given for now - and we are planning on putting decent quality original content on it). Thanks in advance for the input! Aviva
