If the title of your post does not contain the key words that you want to be searched by, use a custom URL, or the slug, to include the key words you want. Make sure you insert a dash in between each word. This allows your post to be searched up using the key words, even if those words are not in your title. 

Below is an example of a post with an abstract title -- using the custom URL, specific words such as "vancouver" and "real-estate" are included so as to allow this article to be searched using these words.
