      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!

              How to NOT appear in Google results in other countries?

              I have ecommerce sites the only serve US and Canada. Is there a way to prevent a site from appearing in the Google results in foreign countries? The reason I ask is that we also have a lot of informational pages that folks in other countries are visiting, then leaving right after reading. This is making our overall Bounce Rate very high (64%). When we segment the GA data to look at just our US visitors, then the Bounce Rate drops a lot. (to 48%) Thanks!

              Number of images on Google?

              Hello here, In the past I was able to find out pretty easily how many images from my website are indexed by Google and inside the Google image search index. But as today looks like Google is not giving you any numbers, it just lists the indexed images. I use the advanced image search, by defining my domain name for the "site or domain" field: http://www.google.com/advanced_image_search and then Google returns all the images coming from my website. Is there any way to know the actual number of images indexed? Any ideas are very welcome! Thank you in advance.

              Google is displaying wrong address

              I have a client whose Google Places listing is not showing correctly. We have control of the page, and have the address verified by postcard. Yet when we view the listing it shows a totally different address that is miles away and on a totally different street. We have relogged into manage the business listing and all of the info is correct. We dragged the marker and submitted it to them that they had things wrong and left a note with the right address. Why would this happen and how can we fix it? Right now they rank highly but with a blatantly wrong address.

              Google Indexing Feedburner Links???

              I just noticed that for lots of the articles on my website, there are two results in Google's index. For instance: http://www.thewebhostinghero.com/articles/tools-for-creating-wordpress-plugins.html and http://www.thewebhostinghero.com/articles/tools-for-creating-wordpress-plugins.html?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+thewebhostinghero+(TheWebHostingHero.com) Now my Feedburner feed is set to "noindex" and it's always been that way. The canonical tag on the webpage is set to: rel='canonical' href='http://www.thewebhostinghero.com/articles/tools-for-creating-wordpress-plugins.html' /> The robots tag is set to: name="robots" content="index,follow,noodp" /> I found out that there are scrapper sites that are linking to my content using the Feedburner link. So should the robots tag be set to "noindex" when the requested URL is different from the canonical URL? If so, is there an easy way to do this in Wordpress?

              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!

              301 Redirect - What happens to backlinks

              Hello... One of my sites is losing rankings in G. I received the webmaster notification of unnatural links... My question is, should i do a 301 redirect of every page on my site to a new domain? If so, do the backlinks (which i believe are causing my rankings to drop) carry over? How about the good backlinks? Also, what would happen to the rankings i currently have on page 1? Thanks
