I am new in search engine optimization sector. I have a confusion in content marketing system. I want to use same content for all article submitting sites or web 2.0 site. Would Google detect it as spam ? Or I need different contents for each site?
I think google would detect it as spam, that's why with SEO, the content must be unique. Maybe you can try to get some help from content writing sites like Textun (https://www.textun.com/)
Yes, definitely Google will consider it as a spam and penalize your website. We would like to suggest you to please use only unique and user friendly stuff in every article, blog, webs 2.0 etc.
