I created my first amazon affiliate website last year and made the mistake of adding the year in the URL of my review articles which look something like: www.mywebsite.com/best-tv-speakers-2016/ www.mywebsite.com/best-tv-cleaners-2016/ and so on. I've already built some backlinks to these pages and am ranking in the top 30s for some keywords. The problem is that 2016 is over, but my URLs still have 2016 in them. I've already updated the title of these articles from 2016 to 2017. My question is : Do i need to change the URL of these pages as well ?
