Everyone with a blog should want to have their blogs reached by popular search engines, such as google. Well, one important step is to ensure you have meta tags setup! I'll list here the walkthrough for blogger users!

1-First go to your dashboard and click on "Layout"
2-Click "Edit HTML" and find this line .
3-Directly beneath it, copy/paste these:

<meta content="ADD YOUR SITE DESCRIPTION HERE" name="description"> <meta content="ADD YOUR KEYWORDS HERE" name="keywords"> <meta content="ADD YOUR NAME HERE" name="author">

That's it! But make sure you choose your description and keywords very wisely, otherwise it won't be as effective!
