Heart of the Home Dining

So I am not computer savvy at all, but I am learning. Have you ever wondered why when you are searching for something on the web a large variety of web sites will pop up, some that may only have one word from your search.  Heard of organic search engine marketing?  Some organic search results are listings on search engine results pages that appear because of their relevance to the search terms, and generally these aren’t advertisements, they are links to multiple site with information.  Most of the non-organic searches will most  likely to pull up advertisements for products or companies. Reminds me of food; they say organic is better for you than non organic, wonder if this holds true to web searches as well?
