To make your huppage more searchable on Google use the Google Keyword Seach Tool that will give you the most searched keywords.
Write your hubpage with relevance to your intended audience. Save as an unpublished hubpage. Then research the Google Search Engine Tool to find out the most searchable keywords and make the necessary replacements.
Do not publish your huppage article to get an URL until after you have replaced unsearchable words with keywords used by internet users.
You can not change the URL once you publish your hubpage article so you must first save the draft as unpublished. The Google search engine uses the URL to transport your article of keywords to internet users who are interested in your niche or topic of writing.
