That probably was the first lesson, but I still spent another two decades before it fully sank in.
There are many things that, even though not rocket science, are quite specialist in nature and it takes time and experience to get to the level where you can do just as good a job as a specialist.
So - yeah, delegate, but some things you can't delegate. No idea about their business in particular, but for a lot of online businesses, keeping track of the basics is probably something you ought to have a feel for yourself.
It's similar to the idea that tech startups are most likely better off not outsourcing their development work.
However, I'm curious about your "not rocket science" comment. I've always generally agreed with you, but I've been watching a lot of twist lately and Calacanis keeps saying stuff about SEO guys making crazy salaries ($100k - $200k/yr). If it's really that simple, how are some guys pulling that much $?
I think at a minimum I'd only consider hiring someone with actual development skills.
accounting services and accounting service are different, with substantial gaps in search volume and competitiveness. Do you know which one is worth more? Do you know how much more?
There's an order of magnitude difference between the traffic on nj accounting firms and new jersey account firms. Are you sure you know which is better?
Even if you cultivate a list of hundreds keywords that are relevant, valuable and that you can be competitive in, do you know how to decide which words to try to hit via SEO and which to do via SEM? Do you have a tool that can help you make that decision quickly?
Do you know who your competitors are, what keywords they're winning on, and how strong they are on each, so you can plan an effective attack, leaving them only with the crap you don't want?
Sure, it's pretty easy to say use valid html, use alt tags, use meaningful URLs, have a header, use relevant images, make videos, get links from relevant content with good anchor text, and all the other crap that goes into SEO 101. But when you get into market analysis, competitive analysis, management of link-building campaigns, etc, it gets very involved. I'd expect that it would take smart person a year of working full-time under an expert to be good at it.... and I'd expect it to take them much longer if they're doing a part-time self-guided tour.
