SEO or google just means a link to another domain or site is considered a vote or endorsement. The goal is to:
1. Make humans and robots indistinguishable
2. Give the administrator and anti-robot a reason not to remove the links
Strength in numbers means as fewer people pay for advertising, as Google and Facebook combine for 87% of the world's Internet advertising, if we have a shared, encrypted robot-blast, Google and Facebook will have a lot less money to pay human censors. The small websites potentially benefit from robot back-links, if:
1. They are keyword relevant
2. They pay an affiliate commission
3. They sell complimentary, not supplementary, products (eg. socks and laces on a shoes website)
4. They represent fresh content, otherwise authority URL's that rank high and are grandfathered fall in the rankings unless they have new material from remote IP addresses recommending external domains.
