Google’s rumored to be updating their page ranking again. They adjust rankings from time to time to improve search results and make it harder to game the ranking system. Bloggersneed provide the best paid traffic sources.
These updates illustrate the problem of depending on organic traffic (e.g. clicks generated from showing up in the search results) vs paid ad links. You can do a great “search engine optimization” (SEO) job and get ranked #1 when you search for “fios battery“, but then Google can change everything and you drop to #7. Clicks will drop off accordingly.
I’m usually skeptical of business plans that depend heavily on organic traffic. Organic traffic should be viewed as “icing” — great if you can get it, but not critical for the business to work.
