Some High Paying, Expensive Adsense Keywords
A few weeks ago while doing some keyword research for one of my hubs, I stumbled on some very high paying adsense keywords completely by accident. My plan was to write a hub for each one, sit back and retire as the Adsense earnings came rolling in, but as often happens with the best laid plans, life got in the way! I realised there was no way on earth I was going to have the time to write so many hubs, especially on topics I would need to do a great deal of research on.
So I thought to myself, after sitting on these keywords for all these weeks, I would be happier just sharing them with the HubPages community and relieve myself of the burden of them!

How to Use High Paying Adsense Keywords
In my opinion the best way to benefit form these keywords is to choose 2 or 3 that are closely related such as:
sell your house and rent it back
sell house to rent back
sell and rent back house
Then write a hub on that topic. It could be about the benefits and the pitfalls of this kind of solution to money problems. Think about why someone might be considering such as drastic solution to their problem e.g. to stop repossession of their home. Try to look at the problem from their point of view in your hub.
If it's a topic you don't know much about then do some reseach. Google news articles are a good way to get up to date information. Do a search on the topic you want to find out about.
Make sure the article you write is going to be of use to the reader and not an article just stuffed full of keywords! if your reader finds it useful they will probably bookmark it and this counts as a back link which is good for you. If your article is just spam, google will rank it down and you won't get any click through = no money!
Even though your primary purpose is to earn money still put in the effort and make sure your hub is well written and worth reading. Ensure your article or hub is content rich and that the information you provide is valuable to the reader.
