We can use tag clouds to know how often words are repeated in a text; we can visualize word frequency.
It's very easy to use; you just have to copy a text and paste it in the site and, after that, copy the embedding code and paste it in a post to be published in your blog.
Here's one of the sites you can use: http://www.wordle.net/
- Go there and click on "create".
- You can either choose to give your blog's url or paste the text of one of your post -your description for example.
- Once you've done it, you can choose the colour, font, layout (horizontal, vertical), etc. You'll find these option on top of the word cloud.
- Save it.
- Get the code where it says "Paste this code into your blog or home page to link to this Wordle:"
