Good Question… I always suggest my clients to use WordPress platform for developing a website especially for dental websites. Many dentist like to blog and to change the content of their website pages by themselves. So WordPress platform from that perceptive will provide easy editing capabilities to update website pages and to blog 24×7.
Besides just being the CMS (Content Management System) platform, WordPress is very SEO friendly and on my experience it may help your site to be better SEO optimized on Google, Yahoo and Bing search engines. Therefore WordPress is very good for your dental SEO campaign.
When adding your articles a few plugins will allow you to instantly create SEO friendly URLS and also meta descriptions that are important to your Dental SEO work as well. Another important point is that when you add images to your pages or posts you are given a field to quickly add the alt tag meaning your site shouldn’t end up with missing alt tags that could penalize your site.
