Whenever you create a new blog post on your WordPress website, you are probably thinking more about creating the right content for your visitor rather than catering to a search engine robot. If you do focus on the robot, then you run the risk of writing for a machine rather than for your human audience.
What often happens is that many website owners will notice that the search engines tend to summarize each post of their website in the search engine results by entering a brief summary. This summary is generally the first 156 characters of the content in their post.
By design, this approach works quite well. Since most writers tend to begin each post with a general statement about what they will be discussing, it can provide for a natural and automatic process for giving potential visitors an idea about what content may appear in your post right from the search engine results page. Depending on your style of writing, this could work well or it could backfire.
Manual Meta Description
There is an alternative though. You have the option of manually creating the meta description for each post on your WordPress website. This can allow you to either stick with the first portion of your site as the default, or you can paste in a highly desirable portion that might stand out better in the list of search results. If your meta description does a better job of answering the inquiry of the searcher, then you stand to benefit from an improved click-through rate from the results page.
By default, WordPress installs do not have a separate meta description. You can easily change this by adding a plugin.
