      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.

                Hi Guys Just curious to hear what you guys do to rank blog posts in the top in Google especially onsite, after the RankBrain update? Do you still use SEO tools to optimize this or are the SEO tools outdated for this? If yes which tools do you use to get success with? Cheers John

                Sub-domain with spammy content and links: Any impact on main website rankings?

                Hi all, One of our sub-domains is forums. Our users will be discussing about our product and many related things. But some of the users in forum are adding a lot of spammy content everyday. I just wonder whether this scenario is ruining our ranking efforts of main website? A sub domain with spammy content really kills the ranking of main website? Thanks

                Using Brand value for SEO: Can we use keyword with brand name?

                Hi Moz community, I am curious to know this. Let's say there is a brand value for a company. It has it's own popularity that it's been mentioned across the internet and social media directly with brand name without their service or industry keyword. Now if the company started promoting themselves like keyword along with their brand name, will it help them to rank for that keyword. For example, Moz is already famous, now they want to rank for "SEO" and related keywords, so they started calling themselves on internet "Moz SEO"; will this fetch them in ranking for keyword SEO? My ultimate question is, using primary keyword along with brand name will work out in ranking for that primary keyword or not? Thanks

                More pages or less pages for best SEO practices?

                Hi all, I would like to know the community's opinion on this. A website with more pages or less pages will rank better? Websites with more pages have an advantage of more landing pages for targeted keywords. Less pages will have advantage of holding up page rank with limited pages which might impact in better ranking of pages. I know this is highly dependent. I mean to get answers for an ideal website. Thanks,

                US domain pages showing up in Google UK SERP

                Hi, Our website which was predominantly for UK market was setup with a .com extension and only two years ago other domains were added - US (.us) , IE (.ie), EU (.eu) & AU (.com.au) Last year in July, we noticed that few .us domain urls were showing up in UK SERPs and we realized the sitemap for .us site was incorrectly referring to UK (.com) so we corrected that and the .us domain urls stopped appearing in the SERP. Not sure if this actually fixed the issue or was such coincidental. However in last couple of weeks more than 3 .us domain urls are showing for each brand search made on Google UK and sometimes it replaces the .com results all together. I have double checked the PA for US pages, they are far below the UK ones. Has anyone noticed similar behaviour &/or could anyone please help me troubleshoot this issue? Thanks in advance, R

                How Additional Characters and Numbers in URL affect SEO

                Hi fellow SEOmozers, I noticed that a lot of websites have additional characters and words at the end of the URL in addition keyword optimized URL.  Mostly for E-Commerce sites For example: www.yoursite.com/category/keyword?id=12345&Keyword--Category--cm_jdkfls_dklj  or wwww.yoursite.com/category/keyword#83939=-37292 My question is how does the additional characters or parameters(not necessarily tracking parameters) affect SEO? Does it matter if i have additional keywords in the additional stuff in the URL (1st url example)? If you can provide more information, that would be helpful. Thank you!

                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?

                What are the good strategies using satellite sites in SEO??

                Hello to everybody, We'are thinking about launching a massive amount of satellite websites in order to promote our website. Is it really efficient in terms of link building? Or is the ROI really small due to the amount of time and money needed to create and manage these websites? Thanks a lot!!! Update: Thanks to all of you for all these interesting answers!
