| scraped content | Taking content from websites that you do not own and republishing it without permission on your own site. |
| security protocol | HTTPS is the secure version of HTTP, a protocol of the World Wide Web. It encrypts session data over SSL or TLS protocol instead of using plain text in socket communications. Basically, a website that uses HTTPS is safer as it is encrypted and thus makes it safer for you to visit that website. |
| keyword cannibalisation | excessive reuse of the same keyword on too many web pages within the same site. Cannibalisation makes it difficult for users and search engines to determine which page is most relevant for the keyword. |
