There is an old saying build your house on a weak foundation it will come a tumbling down. Problem is most companies now don't even have a business plan. If I were to ask them what happens if you lose your traffic what then they can't answer the question.
If you have a business and can't answer the question well your house is built on sand and it will come down around you.
I can remember very well this same discussion about 4 years ago so I asked our CEO that same question. He didn't have a plan either.
So the company I work "with" not "for" we sat down and had that discussion about 4 years ago. Got us all sober so we set out to move our house from sand to rock. It has taken us about that long to develop a business that will survive with or without Google. Now we still have the other business that would die fade out be gone if we were to lose our standings, but with a plan we set in motion 4 years ago we would be just fine.
Without a plan your done. Do you have a backup plan if your servers were to crash, burn, go up in smoke? Do ya have a plan for the future of your business and it all centers around Google? I guess it is time for all of us again to look at our business plan get sober and get creative.
