Let's clear up any confusion there might be about what SEO is and what YourAmigo does.
According to Google, "Search engine optimization is often about making small modifications to parts of your website."
SEO practitioners work on the site's code to improve its visibility and ranking in the search engines.
According to the Search Engine Marketing Professionals Organization, SEMPO, this is what SEO is, "SEO - Acronym for "Search Engine Optimization." This is the process of editing a web site's content and code in order to improve visibility within one or more search engines."
It is widely acknowledged that SEO is typically labor-intensive and therefore this manual approach to SEO gets traffic and sales on a few keywords, especially for very large websites of thousands or hundreds of thousands of pages, so the volume of traffic and sales through organic search is usually a small fraction of other online marketing programs such as paid search.
Even if you have some sort of SEO tools which enable you to work on large numbers of web pages, SEO involves making basic improvements to your existing site content through improvement of key metadata and tags. Off-site optimization may also include external linking strategies of course. All of the above still only results in a relatively small impact on total site revenue.
Ranking highly on only a few keywords or the names of your products through SEO is limiting the volume of traffic and revenue that can be captured through organic search. This is because each searcher is unique - even for the same product each searcher typically uses different keywords to express what they are seeking to purchase.
