      I'm looking to boost my website ranking and drive more traffic to it using a keyword rich domain name. I want to have my nearest city followed by the keyword "seo" in the domain name but the .co.uk and .com have already been taken.

      Should I take the plunge and buy .co at a higher price? What options do I have?

      Also whilst we're on domains and URL's is it best to separate keywords in url's with a (_) or a (-)?

      Many thanks for any help with this matter.

      Alex

        Just to add a couple quick points to the good answers above:

        It's not possible to use the underscore "_" in domain names - not a legal character.

        As far as using the .co because the .com and .co.uk are already in use - bad idea for another reason. The reality is most people are still not familiar the.co TLD (probably a bit more so in UK where they're already used to hearing .co.uk)

        This means a huge number of your potential customers will accidentally type in (when going direct in the browser's URL bar and when linking from their own sites) the more common TLD, resulting in your hard promotional work sending your business to your competitors.

        Not to mention the massive headaches when email addresses are accidentally written with the wrong domain ending.

        The .co is an interesting addition, but it's still way too far out of the mainstream to risk as your primary domain at this stage, IMO.

          nops for pages within the domain you should use '-' to separate it instead of '_'.

          The reason why you should not do this in the main domain is because it looks spammy to many people as this is the format that most spammers use when buying keyword rich domain names...

            "For separating keywords in the domain i would say do not use it and if it is necessary then use ‘-’ instead of ‘_’."

            Should this also apply to pages within a domain?

              Let’s talk completely about branding, I would never recommend you to go for .co domain when .com and co.uk is already taken by other companies...

              It’s always an advantage to me to add keyword in the domain name but don’t push it too much if you are not getting it focus more on branding and choose a domain name that is easy to remember.

              For separating keywords in the domain i would say do not use it and if it is necessary then use ‘-’ instead of ‘_’.

              Hope this help!

                You should read this really interesting post about EMDs by Dr. Pete:

                Are Exact-Match Domains (EMDs) in Decline?

                In your case I would just stick to a .com domain with your business name rather than a keyword rich domain. Also if you are competing in the SEO industry and you do not already rank well for your key terms, then you will find it hard to rank regardless. SEO terms are highly competitive and there are several sites offering this service that will have invested heavily in their own SEO, making it very difficult to compete.

                In terms of your other question, it is generally best practice to separate words in a URL with a hyphen (-) rather than underscore (_).

                Hope this helps,

                Adam.

                  Does redirecting from a "bad" domain "infect" the new domain?

                  Hi all, So a complicated question that requires a little background. I bought unseenjapan.com to serve as a legitimate news site about a year ago. Social media and content growth has been good. Unfortunately, one thing I didn't realize when I bought this domain was that it used to be a porn site. I've managed to muck out some of the damage already - primarily, I got major vendors like Macafee and OpenDNS to remove the "porn" categorization, which has unblocked the site at most schools & locations w/ public wifi. The sticky bit, however, is Google. Google has the domain filtered under SafeSearch, which means we're losing - and will continue to lose - a ton of organic traffic. I'm trying to figure out how to deal with this, and appeal the decision. Unfortunately, Google's Reconsideration Request form currently doesn't work unless your site has an existing manual action against it (mine does not). I've also heard such requests, even if I did figure out how to make them, often just get ignored for months on end. Now, I have a back up plan. I've registered unseen-japan.com, and I could just move my domain over to the new domain if I can't get this issue resolved. It would allow me to be on a domain with a clean history while not having to change my brand. But if I do that, and I set up 301 redirects from the former domain, will it simply cause the new domain to be perceived as an "adult" domain by Google? I.e., will the former URL's bad reputation carry over to the new one? I haven't made a decision one way or the other yet, so any insights are appreciated.

                  301 Redirecting from domain to subdomain

                  We're taking on a redesign of our corporate site on our main domain.  We also have a number of well established, product based subdomains. There are a number of content pages that currently live on the corporate site that rank well, and bring in a great deal of traffic, though we are considering placing 301 redirects in place to point that traffic to the appropriate pages on the subdomains. If redirected correctly, can we expect the SEO value of the content pages currently living on the corporate site to transfer to the subdomains, or will we be negatively impacting our SEO by transferring this content from one domain to multiple subdomains?

                  How Can I Redirect an Old Domain to Our New Domain in .htaccess?

                  There is an old version of http://chesapeakeregional.com still floating around the web here: http://www.dev3.com.php53-24.dfw1-2.websitetestlink.com/component/content/category/20-our-services. Various iterations of this domain pop up when I do certain site:searches and for some queries as well (such as "Diagnostic Center of Chesapeake"). About 3 months ago the websitetestlink site had files and a fully functional navigation but now it mostly returns 404 or 500 errors. I'd like to redirect the site to our newer site, but don't believe I can do that in chesapeakeregional.com's .htaccess file. Is that so and would I need access to the websitetestlink .htaccess to forward the domain? Note* I (nor anyone else in our organization) has the login for the old site. The new site went live about 9 months before I arrived at the organization and I've been slowly putting the pieces together since arriving.

                  Primary Domain or Redirect?

                  We are starting a new travel guide for a resort town. I have bought an expired domain with decent related links and PR (which seems to have survived the transfer (4 months ago). Beofre we launch the new site I am trying to decide if we should use this expired domain as the primary URL for the new site or just do a permanent redirect and buy a new domain that better matches the theme of the site. I am obviously concerned with starting from scatch with a new domain. I am confident we can build some good rellevant links in a short time but this space is very competetive. Any input would be greatly appreciated.

                  Redirect old .net domain to new .com domain

                  I have a quick question that I think I know the answer to but I wanted to get some feedback to make sure or see if there's additional feedback. The long and short of it is that I'm working with a site that currently has a .net domain that they've been running for 6 years. They've recently bought a .com of the same name as well. So the question is: I think it's obviously preferable to keep the .net and just direct the .com to it. However, if they would prefer to have the .com domain, is 301'ing the .net to the .com going to lose a lot of the equity they've built up in the site over the past  years? And are there any steps that would make such a move easier? Also, if you have any tips or insight just into a general transition of this nature it would be much appreciated. Thanks!

                  Keep multiple domains or combine them?

                  I need some help figuring out if I should combine multiple domains or if I should let them be separate? I have domain1.com, domain2.com, and domain3.com. Well, domain1.com owns domain2.com and domain3.com. And currently domain1.com points to domain2.com and domain3.com from the homepage. They are going through some changes at their business, and now the option is on the table to combine the domains or still let them be separate as long as they link to each other. What is the best way to handle this and are there more things I should go through before making a decision? None of them have a ton of links to them, and they aren't super robust, but would just to have some advice. Thanks a lot

                  Is it worth switching from .net to .com if you own both domain names

                  For over 20 years the company I work for has used www.company.net as their TLD, because we could not register www.company.com at that time. However, currently we also own www.company.com www.company.com has a 301 re-direct to www.company.net  We are a global company, and market leader in our industry. Our company name is associated with the product we make, and our competitors use our company name as their targeted keywords to attract visitors to their sites because our company name is synonym with the product we and they make. As we are a global company we also have lots of TLDcc's. The email address of all our employees worldwide have a .net email address extension. Would you advice switching from www.company.net to www.company.com??? And if so, what would be the reasons for this switch. Would it only be for branding purposes? Looking forward to some insights before taking on such an invasive switch (because of the switch of all email addresses of employees worldwide). Best regards, Astrid Groeneveld
