I have a site techbymak.com and there are several duplicate pages Indexed on Google. I know how to deindex them but is there any way to stop it cause whenver I will add any new site there will be a duplicate link indexed in google . How to prevent this ?
First of all, you have to remove all duplicate pages in your website and then implement the canonical tag in home page coding of your website so that Google crawler understand the duplicate issues in your website...or you can use the robot.txt file to inform the search engines,not to crawl that particular pages of your website.
