I found a great video explaining how Google works, This is why headings, articles, topics, meta tags, links, more articles and more links are so important.
I would think that this is how all search engines work.
I offer a method at a low cost to link or submit your website to hundreds of other search engines and this video explains that the more places that the internal spiders (a program) find links to your website the better for you. The headings as well as articles must be written well and you must have all the ingredients that are explained in this video. My offering is only a small part in the process but it is an important one that can be taken care of over time.
