Reading a post with all text and no pictures is like eating a salad without any dressing- it's very healthy and does you a lot of good but trying to get through a plateful can get a bit drab and tiring.
While keyword embedded content is certainly one of the ways to increase traffic to your blog, adding a couple of colorful and lively photographs will instantly enhance its appeal.
A Picture Speaks A Thousand Words Sure, blogging is all about chatting and exchanging information but one relevant picture could convey more information to your reader in a second than all the words in your blog put together.
How do describe to your readers the exact color of the product you are talking about? If you are posting a book review on your blog, how do you describe the charming illustration on the cover? A photograph of the product or of the book cover could achieve in a flash what you could never hope to achieve with all the words in your blog post.
So where do you get your Pictures from? It's always best to use your own if you have a relevant photograph in your cache.
If you don't, you could always choose an image from the several that come with publishing rights including those available on Flickr.
com or those that are published under a Creative Commons license.
In the event that you cannot find a suitable picture, you could post an arresting graphic that is distantly related and add a witty heading that connects the two.
