Difference Between PPC Marketing And Search Engine Optimization (SEO) ?

I analyze that PPC is only the Part of the Seo but the question is Why Seo is there?

If we Analyze PPC. This is Only the medium of approaching Visitors for instant. If PPC is better than SEO then why we are doing SEO if PPC is helpful to approach visitors instantly. There I have to clarify that PPC is the medium that we can approach Visitors for a limited period and this is not helpful on Ranking of search engine as Google already clear that statement in their PPC terms. PPC is one time visitor approaching process and so many times competitors click on ads on their competitive site and it turn to wastage of Money And that click not convert into query and Site Face a White HAT Scam. PPC also costly than Seo.

In other Hand , Seo includes Link Building , Article Submission, Press Real eases Etc Etc. that convert traffic to the website for a long time. Seo Also improve ranking on search Engines And that help Our website to generate more traffic from the Search Engine's. As we already Know that 70% of Website Traffic comes from Search Engines. Seo is also Cost effective process. that Surely provide return to the website Owner .

Note :- Seo is long time process and it take time to convert visitor into query. We can Use PPC for instant push of traffic on the website that helpful to the new website’s.
