Irving, I am new at SEO making me a newbie.. The website was changed completely from the old site, removing external links, cleaning the code and changing the design.
Thanks for your response, i will use the canonical tags you mention.
I have just re created my website as I noticed a massive fall after the update.
Can anyone tell me if there is anything more I can do to improve SEO for Google UK for the term - radio codes. Please be constructive I am a small business working from home trying to get high in the organic listings again.
