I’ve just stumbled upon a nice little tool from Google to help you with keyword ideas. Have a look what happens when I search on ‘mumpreneur’ here. Instead of getting just a list of results, I get a ‘wonder wheel’. It’s a bit like a mind map: just enter your term, then click on the suggested similar terms to find even more possible keywords.
To find it, do your usual search, then select ‘options’ on the left of the blue bar running across the screen above your results. Then, scroll down to click on ‘wonder wheel’ in the left column. Then, you can have fun looking for new keywords which people might use when searching for your products or services.
