How do you know an industry is maturing?
It gets its own trade magazine.
Such is the case with the Search Engine Marketing Industry, which this year is getting its very own “Search Engine Marketing Standard” magazine which will be published on a quarterly basis.
Right now, residents of the USA can get a free 1-year subscription through SearchMarketingStandard.com. International subscriptions are only $20 USD/year.
The first issue is being published in May. I’m looking forward to reading it.
