      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!

              Prevent Google from crawling Ajax

              With Google figuring out how to make Ajax and JS more searchable/indexable, I am curious on thoughts or techniques to prevent this. Here's my Situation, we have a page that we do not ever want to be indexed/crawled or other. Currently we have the nofollow/noindex command, but due to technical changes for our site the method in which this information is being implemented if it is ever displayed it will not have the ability to block the content from search. It is also the decision of the business to not list the file in robots.txt due to the sensitivity of the content. Basically, this content doesn't exist unless something super important happens, and even if something super important happens, we do not want Google to know of its existence. Since the Dev team is planning on using Ajax/JS to pull in this content if the business turns it on, the concern is that it will be on the homepage and Google could index it. So the questions that I was asked; if Google can/does index, how long would that piece of content potentially appear in the SERPs? Can we block Google from caring about and indexing this section of content on the homepage? Sorry for the vagueness of this question, it's very sensitive in nature and I am trying to avoid too many specifics. I am able to discuss this in a more private way if necessary. Thanks!

              Will Google View Using Google Translate As Duplicate?

              If I have a page in English, which exist on 100 other websites, we have a case where my website has duplicate content. What if I use Google Translate to translate the page from English to Japanese, as the only website doing this translation will my page get credit for producing original content? Or, will Google view my page as duplicate content, because Google can tell it is translated from an original English page, which runs on 100+ different websites, since Google Translate is Google's own software?

              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?

              Multiple Authors Google + Authorship

              Hello, I took a look through past questions but can't seem to find a definitive answer on setting up Google + Authorship credit (for multiple authors) using a Wordpress blog. Has anyone had experience setting this up? Or could you recommend solid reading/research? I took a look at a couple of Wordpress plug in's but just found them very confusing (so did our IT contact who will ultimately be setting up code for this.) Any direction or advice is appreciated.

              Can Google read my backlink in Javascript??

              Hi SeoMoz community! I have a software product, which our clients implement onto their websites. It is like a pop up box. I know that backlinks are very important for SEO ranking, and I really want to give our clients 2 options of product: 1. you can get the free/cheaper option if you use the code which has a keyworded backlink to our site on it 2. you can pay small fee if you don't want to use the version with a link to our site on it Now, the problem is that the product is written entirely in Javascript, and I don't think that Google crawls this, do they? Is there a way around this? Thanks for your help!

              Check Google ban on domainname

              Hello all, If I wanted to know if a domainname has a google ban on it would the following be a good idea to test it. Place an article on the domain page with unique content and then link to the page so its gets indexed and then link to the article from a well indexed page. If it doesn't get indexed there might be a ban on the page, if it does get indexed there is no ban on the page... Or are there other points I should keep in mind while doing this. All help is very welcome. Cheers, Arnout
