Benefits of using this plugin:
Multiple Websites – Each subdomain is considered a separate website, with each website having it’s own Google PageRank. PageRank is Google’s way of letting you know how important of each page of your website. Better-SEO
Total Web Domination – By having multiple websites, you have more opportunity to show up multiple times in a search engine results page, therefore pushing other websites down the page and achieving “Total Web Domination”
Local Control – The people running the local business can have control over their own content.
They would have control over their subdomain website to post a new photo each week.
Local Optimization of each page – Because the subdomain has the word, every page of this site is automatically associated with business in that word.
Promotion of Main Domain – because each subdomain has the main domain in it’s URL, it ties all subdomain sites back to the main domain, which would have more corporate information and promotion of each subdomain.
Internal and External Linking – Google gives websites better PageRank if there are external websites linking to pages of your website, or links within your website, to other pages of your website. In the case of multiple subdomain websites you would cross-link the sites to help each site get better Ranking in Google. As of the summer of 2011, Google considers all linking between subdomain websites, to the main domain or other subdomains an internal link.
Why Would You Use a Subdomain?
To make it simple, a subdomain is a part of the main website. But, it’s considered a separate entity by the search engines. Subdomains can be used for organizational purposes, or even for an SEO boost.
Sometimes you don’t want certain pages of your site indexed with the rest of them. We can’t predict your unique circumstance, but some of the most common explanations are below.
Subdomains and SEO
Your subdomains will be treated as entirely separate websites in the eyes of Google, as Matt Cutts explains:
This means you can create unique authority for each of the subdomains you’re using. Subdomains can actually be beneficial to your SEO efforts, as you’ll see below.
1. Subdomains Can Insert Keywords Into URL
Sometimes it just doesn’t make sense to fit certain keywords into your main URL. But, with subdomains you have another chance to insert hard-to-rank keywords into your domain. Which will never be a bad thing for your rankings.
2. Subdomains Can Improve User Experience
If you have a large and confusing site that’s hard to navigate, you’re going to provide a poor user experience. A poor user experience means your users will spend less time on your site, which can lead to lower rankings.
3. Subdomains Can Grow Niche Authority
Building large-scale authority can be a lot of work. However, ranking in niche markets can take a lot less time and energy. By ranking and building authority and smaller markets this authority you build will help to reinforce the authority of the main domain.
We hope that you now have a better understanding of subdomains and the role they can play throughout your site’s organization and your existing SEO strategy.
