For example: If you're a shoe shop and you're having a sale, don't just title your blog post with the words "50% off Sale!" This won't help your blog post come up in search results. Try and add in some of the words your potential customers are searching the internet for. So, in this instance that may be your most popular shoes on sale.
Also, if it doesn't look too cheesy, add in the name of your shop. The more relevant articles and posts that mention your store name, even if it is linking from your own website - the better.
Do keep in mind though that if you pour it on too thick (like naming every brand you carry) the result will be the opposite and Google will mark it as a non-reputable site. So, just be clear, helpful and relevant with your titles and content. That'll lead you to success.
