Sites which focus on monetizing organic search through ad revenue, rather than selling a product or service directly, can be subject to both volatility and algorithm changes that often occur in organic search. This points to the unsustainable nature of businesses which rely on free traffic as their only source of income. When it comes to ad revenue resulting from non-commercial search traffic, the Google gods certainly giveth and taketh away as they please. While it is important to recognize new problems and opportunities resulting from this latest update, “Farmer” doesn’t materially change the way we do search engine optimization. Focusing on creating high quality, keyword relevant content, and earning links from authoritative sites is still the foundation of any successful SEO campaign, but long term success hinges on your ability to convert traffic from diverse sources into leads and sales.
