Writing search engine friendly texts is no rocket science. Here are some simple tips to score higher in Google.
1. Product title
Consider with the product title which keyword combination will be used the most when a customer searches for such a product. (for example: mouse pad with logo)
2. Intro
Also put this most important keyword combination in the first paragraph of the description.
3. Description
Have the keyword combination come back one more time in the text. Ensure variation by using other keyword combinations in the further description and by discussing the various versions and printing options. Make the text longer than 300 words, with the most relevant and promotional text is in the first 50 words.
