      I find addon domains really confusing. Everyone I've asked so far says that they don't affect SEO but I find that really hard to believe considering the same content is on both a subdomain and a subfolder and also has it's own unique domain. PLUS (in my case) completely different niche sites are sharing the same hosting.

      I really don't want to pay for hosting for all of my different sites but at the same time, if it's better/safer to do so for Panda/Penguin reasons I'm happy to do that.

      Thank you for your time. I look forward to your opinions/suggestions!

        Thanks again Zach!

        Are you saying that in my htaccess I should be forwarding addon.maindomain.com and maindomain.com/addon to addon.com?

        OR is it more complicated/involved than that.

        I'll def get a developer to do this for me, but I just want to make sure I know what I'm telling them to do and why.

          The virtual host is what tells your web server (Apache) basic details about your website. Where to find it (path), where to store error logs, the domain name, and so forth.

          Unfortunately you will need a developer to do something for you if you aren't too sure about how to go about the process, and especially if you aren't familiar with Linux platforms.

          I'm not suggesting to get a hosting account for every domain -- addon domains are perfectly fine. Just make sure you are redirecting correctly (whether through .htaccess or through cPanel config). I had well over 100 addon domains many years ago when I still used cPanel 🙂

            Thank you Zachary. I really appreciate you taking the time to answer this question for me.

            Can you (or anyone) please clarify what it means to "edit the virtual hosts on the server directly". I'm not really sure what it means and I don't know how to do it either.

            Also, are you suggesting that it's just easier/better to get a complete hosting account for every single domain name?

              I'm assuming you are using cPanel? You are able to enable redirection within your panel. (I haven't seen this issue outside of cPanel)

              Ideally, you are right, you shouldn't have mirror content up. If you can edit the virtual hosts on the server directly that would be another option.

                How important are author bios to SEO?

                I'm trying to understand the importance of author bios to Google and its latest algorithms. Some say author bios affect rankings, but others say that has not been specifically stated by Google — but it does affect the user experience. Anyone have input on this? Thanks!

                Moving established :COM site to a .ART domain

                Hi! We have an existing website that has a .com TLD with our brand name, which is completely unrelated to any of the terms we want to rank for except for the brand search of our company of course. We have an online shop and the .com site has been online for a good few years. The business activity is related to art, in fact some of our customers would search for   "name of artists + art" and we appear in results. From what I have read, Google is not going to give better rankings for a .art domain name, but will the extension be counted as a potential keyword and relevancy to users searches based on example above? Does anyone have any experience with regards to this consideration? Thanks!

                Will Parked Domain hurt My SEO as Duplicate Content?

                Hello, I have one website (Migration Lawyers) and I have an extra 8 domains Parked so they are basically cloning the content of the site. so if the main site is:  migrationlawyers.co.za and I have an addon domain  migration-lawyers.com  is that good or bad? is there a proper way to redirect the sites, will redirecting (301) subdomains be more effective? Thanks for your Input 🙂 0i8VXqr.png

                Does the use of an underscore in filenames adversely affect SEO

                We have had a page which until recently was ranked first or second by Google UK and also worldwide for the term "Snowbee".  It is now no longer in the top 50. I ran a page optimization report on the url and had a very good score.  The only criticism was that I had used an atypical character in the url.  The only unusual character was an underscore "_"    We use the underscore in most file names without apparent problems with search engines. In fact they are automatically created in html files by our ecommerce software, and other pages do not seem to have been so adversely affected. Should we discontinue this practice?  It will be difficult but I'm sure we can overcome this if this is the reason why Google has marked us down.

                Is changing your meta titles frequently good SEO Practice

                Greetings, Im a new SEO and really knew nothing until signing up to SEOMoz. After reading the SEO101 and gathering as much information in a short period of time things started  to become a little clearer. So I started my first campaign used my new SEO knowledge and input all of my meta information. Then I waited a few days to see what happened with my search result. We had never ranked for a single keyword before mind you. So a couple/few of days go by and I started punching in my keywords and looking through the pages. There I was page three. I was SO happy. I read the entire SEO101 again, realized a little more about what I had to do. So I started changing everything up, adding pictures, I found out what a IMG ALT Attributes were in the HTML editor, bolded text and all the other things I missed the first time around. Three days go by and I move up again. I start to notice my traffic is increasing and I am actually getting organic hits through search traffic. This has never happened before. I am over the moon. But I realize that I have my main focus keyword as the second key word in my title tag. So I switch the two words around, wait a few more days. Here's why I ask my question. The original title tag was still showing up and I was on the first page for both keywords, and I could see both title tags when searching for either keyword. So; Is changing your meta titles frequently good SEO Practice ? Warmest regards, Michael S&M Warning: adult site, NSFW

                Plural vs non-plural domain name

                I'm sure this question has been answered and asked a 1,000 different ways but what would be the best domain name to use in the long term (2 years +)? The plural versions (examples.com) which has a decent domain authority and is ranking 1st in Google search results yet has less search volume or the singular version (example.com) that has no current SEO value for the search term that we'd like to target however the singular version of the keyword has a much higher search volume? so basically will it be better to have the exact match that has more volume or the plural form that has better rankings after 2 years of doing SEO for each domain? My guess is that using (examples.com) with the better domain authority and tightening the grip on its dominance in Google will still be more effective than having the exact match domain with more search volume for that keyword while performing the same amount of SEO even after two years. Any suggestions?

                Singular vs plural SEO

                Hi everyone, OK I've been looking at the Google adwords keyword tool and it's thrown some of my On-page SEO into question (everything said here are examples, I haven't used any real life terms or figures). Lets say my page is about "Green Apples", let's say the keyword tool shows that the singular version "Green Apple" gets more searches (as an example). Should I optimize for the singular or the plural? Also lets say my title tag for that page is "Green Apples | Apples Galore UK" would Google/SEOmoz count that as an optimisation for the singular "Green Apple" or do the search engines take the title literally and don't differenciate between singular and plurals? Thanks in advance everyone! Regards, Ash
