Here's a way to find natural keywords for your articles.
The situation is that you write on your blog in a natural way. When you're done, you usually have more than 500 or 750 words, which is enough for an article or several.
The next step is to find an article that has keywords that people naturally use, so that your article will be easy to find. Since you've already put your heart into this and it sounds just like how you would talk to someone in person. You don't want to have to change a bunch of paragraphs just to use some keywords.
The solution is simple: use adwords.google.com. However, this only works if you have a separate web address for each page (as blogspot does). You type in the exact name of the page you want to find keywords for, click the "Get keywords" button, and all the keywords for that page are now available for you to use.
At this point, you can use these keywords to make a new article title, which you can then finalise by searching for. You can also change the title of your blog post to make it easier for people to find it.
Now, it's interesting to note that you can also use these keywords as tags, labels, and so on. Which in turn makes it easier for people to find your pages and articles.
I just found a tool that claims to be able to scrape a site for an article. I'm testing it out now. Now you can take older articles (blog posts) and post them to a few hundred article directories. Each of these directories has ready-made key search terms that you can add to the articles.
Article marketing is a great way to make a lot of money online, and you can do it all from home.
(I wrote the above as a blog post; let's see if it worked...)
Update: Google Keywords found the following groups of keywords: blog, money, making money, earning money, money-making idea, making money online, and other ones like napoleon hill, audio blogger, adwords software, and adwords.
So, an example of an article title could be "How to make money online with Google AdWords without spending a dime by using your blog."
A search shows that a title like that doesn't exist. So I could just put that into my programme for sending out articles and let it go. As long as my bio linked to a relevant product, I'd get clicks. I didn't even have to write from the keywords; I just had to let the keywords come out naturally.
Now, this doesn't take you into the world of niche keywords, which are much more profitable, but that's just another way to research.
(And the above has 411 words, which is enough for an article. Nice.)
