Did you ignore the hype over the last 10 years about SEO? Are you tired of the emails, spam and phone calls with big claims "We can make you #1 on Google in 7 days"? The idea of a brick and mortar business relying on the invisible world of the Internet or SEO where terms about "keyword ranking" have been foreign.
It no longer matters. The tricks, strategies, tactics, white hat, gray hat and black hat for keyword ranking is being outsmarted by search engine software.
The new world media and technology, Internet marketing, social media, content marketing and the new hot "inbound marketing" has changed. Not everyone has caught up and "experts" will keep trying to sell the old.
