1. Update XML Sitemap. My Drupal site has an automatic XML Sitemap module installed. XML is a programming language, similar to HTML, that search engines like Google and Bing can read. The XML Sitemap is used to provide the search engine your website's complete content and directory structure, and to communicate changes any time there's a new piece of content. My module will update itself regularly, but as soon as I've published a new post I go ahead and run the "cron" job that will update that sitemap, ensuring that Google gets a notification of my new content to be spidered right away. There are several similar plugins for WordPress.
2. Like the post. Somewhere on every blog post, you should have buttons to help readers share your content to social networks. If possible, include widgets for the more popular platforms so that it's easy to provide social signals, and you present visual evidence of popularity. First up is Facebook with a button to Like the post. This doesn't post an update to your feed, but it will place the post in your Likes box on Facebook for your personal profile.
3. +1 the post. Similarly, we need to provide Google+ with a social signal. When my readers come to my blog, I want them to see that there's activity. It's like a party where you show up and there's already people there having a good time. No one wants to be the first person there!
4. Share to Google+. Using the same +1 button, if I leave my mouse hovered over it, a dialogue box comes up that will let me post an update to Google+ and share my new blog. The update will automatically include the title, image and description, so all I need to do is add some commentary. This is where you need to be creative and devote some more time. First, it's important that you introduce your article. Explain a little what it is about or why someone would be interested, and then try to start a discussion by asking related questions. Second, take advantage of Google's formatting options and hashtags to make your post look good and be more easily found.
5. Share to LinkedIn and LinkedIn Groups. Most LinkedIn Share widgets will give you a dialogue box that lets you simultaneously post a status update as well as Group posts. Just as with Google+, the blog will be posted as a title, image and description, but you still want to add that introduction. It can be the same or similar to what you used on Google+. A lot depends on the kinds of conversations you have on one network or the other. Make sure that you're only sharing quality content with appropriate groups, and if you need to adjust the commentary for specific groups so that it creates a better discussion starter, share to those groups separately.
