I Think, you can get all the meaning in just one word "Natural". Paid and Organic its like "Carrot". You are showing to people that come and see this Carrot. Natural searches are always better than because its free, organic, people voted, brand. Google always give more importance for natural and organic ways.
According to me Natural Work and its Search Result is free and good, it is not Spam and it is not hurt our Online Reputation this method is SEO friendly So natural search is important.
It is Important after google updates google wants natural work in seo, by natural work we can achieved at the top rank on the google and get Huge Organic natural traffic as a long time, So natural work is important in seo.
Engine searchers who understand the difference between paid and natural results are more likely to hold the natural search engine results in a higher regard, much like a person reading a magazine would probably be more positively influenced by an article about a particular company than by a paid advertisement from the company.
