Intent is everything, and search engines know San Diego SEO companies and other businesses use duplications for valid reasons, such as those given in the examples below.
Sometimes you find great content on another site and want to share it on your website, which ultimately helps bring traffic to your page as well as the site you sourced the original content from.

Duplicate content is very common on the Internet and is not the most effective online marketing strategy. According to Google, duplicate content is only problematic if it is considered to be spam.
