The surest sign of success is when you're too busy with more important matters to deal with the day-to-day minutia.
When you're occupied making business deals instead of worrying about SEO or publishing additional content, that usually indicates you've made good in-roads. The website has been found, it's making transactions, and hopefully making money.
It's no longer a matter of writing articles every day, or tweaking keywords. Now it's about filling orders, tapping into new markets, dealing with manufacturers, and finding more distributors. Continuing to make sure that the business makes money is important.
But so are those other things.
It's at this point that sometimes being too hands on can be a bad thing.
