I am thinking of migrating my existing html website to wordpress because it makes things easier for me to manage. My site is more than 8 years old and if I migrate to wordpress, all the URLs would change, including the home page. I will have to use 301 redirects for all the old urls. My question is that what are the seo consequences I am looking at for migrating to wordpress? How much authority would my website and individual pages lose from this. Will there be PR loss or something?
301 redirect is SEO practices and works great if you move your sites. This process will help you to move your site without harming your ranking.
