      Hi,

      What does Google look at when assessing a backlink?

      How important is it to get a backlink from a website with relevant content?

      Ex:

      1. Domain/Page Auth 80, website is not relevant. Does not use any of the words in your target term in any area of the website.

      2. Domain/Page Auth 40, website is relevant. Uses the words in your target term multiple times across website.

      Which website example would benefit your SERP's more if you gained a backlink? (and if you can say, how much more would it benefit - low, medium, high).

        Based on my conversations with Google, relevance is absolutely something to think about - if your site is all about oranges and you get links from sites/even blogs that are all about cars, it's  flag because it can look spammy.

        Unless it's an outlier and is just one (or two) random links from sites that aren't related in content to yours, you risk harming yourself by connecting your site with unrelated content.

          Thanks for reply Greg.

          Glade you mentioned Guest blogging because that's what im talking about really.

          Yeah I spoke to Ann Smarty from My Blog Guest and she agreed, DA over relevance (to a certain extent).

          What happens though if you guest post 5 articles to say DA60 blogs where your in travel and the blogs are in SEO?

          I would have thought 5 guest posts on DA40 blogs where your in travel and so are the blogs your posting on would have worked a lot better.

          It's a tough one for me.

            Relevance is important, but then so is the domain authority and trust.

            A link from a news website for example. Its unrelated, but can provide a powerful boost for your websites "trust"

            Your main objective in my opinion should be to get links on relevant websites, however you can mix the two by getting links from high authority, unrelated websites as well. There are a few guest bloggers on SEOMOZ who link to their companies websites totally unrelated to SEO,

            lets say you already had a mix of relevant as well as unrelated high authority links and you had to choose between DA80 (unrelated) and DA40 (related)

            I would go with the most powerful site, DA80

              Are "Powered By..." type footer backlinks good or bad for SEO?

              Hi guys, We're running a software company which is also selling WP themes amongst other things. We've heard recently that footer backlinks like "Powered by BigBangThemes" might do more harm than good. Some clients usually forget to change them - so we want to make sure we stop including them in case this is true. Thanks!

              Geo-Redirect: good idea or not?

              Hi Mozzers, The background: I have this very corporate .com domain which is used worldwide. Next to that, we have another .com domain which is specifically created for the US visitors. Within the organic rankings, we notice that our corporate domain is ranking much better in the US. Many visitors are arriving on this domain. As it is a corporate domain being used worldwide, they get lost. My questions: I know there are ways to redirect by location. Would it be smart to automatically redirect US visitors for the corporate domain to the commercial US-specific domain? Is it possible to only redirect US visitors and leave the website as it is for visitors from other countries. Won't this harm the corporate website (organically) worldwide? If this would be a good idea, any recommended plugins or concrete procedures? Thank you so much for helping me out!

              Google Cache Is Blank for Text-only

              Hi, I'm doing some SEO for www.suprafootwear.com, and for some reason when I go to text-only in google cache, nothing shows up. http://webcache.googleusercontent.com/search?q=cache:suprafootwear.com&es_sm=91&strip=1 That seems to be the case for all of the different pages on the site, but the content is still appearing on the serp.  I have never seen this before, and I'm not sure what's happening. Any help would be greatly appreciated. Thanks!

              Meta Keywords Good or Bad

              Hi All, I've been reading more about the meta keyword tag and why it may not be a good idea to include them on pages and am looking for thoughts/feedback on this idea. If you have employed this tactic, can you give me some insight into any results you saw.  If you decided to not employ this tactic, why did you choose not to? I wan to understand all sides of this before employing any changes to my company's websites. Thank you for your help!

              How does google recognize original content?

              Well, we wrote our own product descriptions for 99% of the products we have. They are all descriptive, has at least 4 bullet points to show best features of the product without reading the all description. So instead using a manufacturer description, we spent $$$$ and worked with a copywriter and still doing the same thing whenever we add a new product to the website. However since we are using a product datafeed and send it to amazon and google, they use our product descriptions too. I always wait couple of days until google crawl our product pages before i send recently added products to amazon or google. I believe if google crawls our product page first, we will be the owner of the content? Am i right? If not i believe amazon is taking advantage of my original content. I am asking it because we are a relatively new ecommerce store (online since feb 1st) while we didn't have a lot of organic traffic in the past, i see that our organic traffic dropped like 50% in April, seems like it was effected latest google update. Since we never bought a link or did black hat link building. Actually we didn't do any link building activity until last month. So google thought that we have a shallow or duplicated content and dropped our rankings? I see that our organic traffic is improving very very slowly since then but basically it is like between 5%-10% of our current daily traffic. What do you guys think? You think all our original content effort is going to trash?

              Google places keyword variations

              Hi all, I have a site that is ranking #1 in Google Places for its main <city><keyword>search... but it does not rank for any of its basic keyword variations, which I find very confusing.</keyword></city> ie (just an example) Chicago Caterer (ranked #1 in google places)
              Chicago Caterers (not ranked in google places)
              Chicago Catering (not ranked in google places)
              Chicago Catering Company (not ranked in google places)
              Chicago Catering Companies (etc..) How can I secure a google places ranking for these simple keyword variations? Do I build links to the google plus page using that anchor text? Do I get citations that contain that keyword somewhere on the page? Do I optimize for these keyword variations on the actual website itself? (not the places listing). Obviously I don't stuff these keywords into the google places listing. Any help would be much appreciated!
