Natural or Organic searches are searches where the results appear because of their relevance to their search terms, rather than being advertisements, including Pay Per Click Advertisements. The latter are known as non as non organic search results. The idea of natural searches is specifically relevant in the world of Search Engine Optimization because unpaid searches are given more value than paid results and appear more prominently on result pages.
Although it seems logical that paid searches should bring about a better result in comparison to an unpaid search, it has been estimated to be the other way around. Figures state that over 80% of the search traffic comes from Organic Searches.
One of the major points of distinction between paid and unpaid searches, outside of the payment bit is the fact that with paid searches, the result is rather instantaneous. In the case of Organic results, the strategy is one which is essentially long term and the ultimate ROI can be measured only over a period of time.
The question that always pops up at this juncture is: Are organic search results trusted more than paid results? If yes, do the regular users know the difference between the two? Studies have proves that while it is not very clear if the difference between the two is acknowledged by everyone, natural search results are trusted my users, even more so than PPC search results.
So, getting your page into the top page of the search pages and specifically into the top three results will yield the best results. What are you waiting for! Get cracking on that SEO!
