Your question and concept is not clear. When you search anything at google then it gives you two types of search results. One are called organic and other are called inorganic or paid search results. the listing of 10 search results are organic and on the other hand, the colored results are paid search results.
Yes, inorganic-or PAID--is Google adwords or any other form of paid results. By the way, these paid results can bring as many hits as your budget allows. But the question is, will the cost of these ads justify the visit? Usually not...unless you are really clever.
Organic - Free Listing :- it means Google show results on the basis of relevancy of sites in there search results.. In-Organic - Paid Listing :- It means Google shows sponsor results on the basis of paid values....
Basic difference between organic and inorganic is, organic is free listing and inorganic you can say paid listing. Generally organic list is preferred in search engine. As organic listing are permanent where paid listing are temporary. Paid listing are ignored by search engines and especially Google ignores paid listing. So try to avoid paid or inorganic listing.
