I'm not making a mass of money through Google Adsense, with the total revenue being just enough to cover hosting costs.
I'm noticing a rather unsettling trend in that one of my sites accounts for most of the earnings from Adsense with the rest contributing little.
Whilst money earned is money earned, I tend to find myself agreeing with those who advise to diversify their income (and have several other sites of a similar size with this half in mind) and so having such skewed earnings is a little worrying.
What should I attempt to do about this?
The site in question doesn't have a vast amount of updates at the moment so should I try hard to add more content to attempt to maximise on the current good payout?
Alternatively should I just accept that this site may drop off at any time and simply enjoy the good payouts it's currently generating (I think this is in part thanks to a good Google ranking for the moment though there are a lot of newer sites like mine now which threaten to effect this). The worry is though if the site does drop then I will be getting virtually nothing from the Adsense program.
