It takes about 30 minutes to get started with google adsense. For the cost of some space on your website and some effort to get the code in you can for little effort earn ... well, possibly peanuts per year depending on the popularity of your site.
But I don't want grotty adverts on my site! I hear you cry. Quite right too. By default google makes its best effort to work out what your page is about and serve relevant ads, but you can also restrict ads by keyword. Google text-only ads are not very intrusive and you can specify an exact colour scheme to match your site.
If you want more control over what you advertise, a better plan might be joining Amazon affiliates, which allows you to advertise a specific product on Amazon's site. That, or go into business yourself.
Of course the fact that I mention these two big names is yet another example of the winner-takes-all nature of internet business: the bigger you are, the bigger you get.
If you're wordpressing on a hosted service, security restrictions may simply stop you doing it. Not much you can do about that except move.
You may have AdBlock or some other ad blocker switched on in your browser – and hence block your own links! Right click on the page and see if you have 'Block an ad on this page' and "Don't run on this domain" in your menu. Choose "Don't run on this domain" to exclude your own site from adblocker. Similarly with other adblock technology.
According to my calculation at the global rich list, if you're on the dole in Britain, you're likely one of the richest people in the world – an income of £80 per week, with no other benefits or income would put you in the top 14% richest people in the world.
We nearly always focus more on comparing ourselves with those richer than us, and ignore those who have less, as if they didn't count. Feeling pressured to keep up with the Joneses? Think of all those people out there who dream of being half as rich as you.
