This is like asking how much effort do i need to put into my business before it runs itself. Even if you get to the tipping point where new customers are finding you by word of mouth, you can’t simply rest on your laurels.
Seo is long term. Time is only guauged in seo to understand how long it will take to catch up with your rivals and even outrank them. But once this is achieved if you sit back and relax, your ranking positions can soon start to slacken.
Apart from slackening off there will always be new avenues to target and keywords you don’t want to waste the time and money to promote again, as they have low commercial value, or perhaps you are getting rid of certain products or services. This is all a natural part of business and whether you do it inhouse or contract it out to a seo consultant this should be part of your marketing plan if you want to stay ahead of the chasing pack.
