Answer: What is SEO???
SEO stands for “search engine optimization.” It is the process of getting traffic from the “free,” “organic,” “editorial” or “natural” search results on search engines. Source
Both major search engines such as Google and Bing provide primary search results, whose web pages as well as other content such as videos , images, or local listings are displayed and ranked based on what the search engine finds most important to users. There's no charge involved, because it's for paid search ads. If you need seo services, I think Kashif M. Aslam provides best seo services in pakistan
