Hey Joe,
The #1 best thing you can do to improve SEO is ensure your site has content in the DOM (unhidden and un-touched by JavaScript) which is relevant to the keyword or phrase you want to target. Within mojoPortal you are free to add keywords and metadata for each page however you like (under page settings, meta data), but I'd like to point out that these things are a lot less important to Google page rank than they used to be. Google has opted more and more to crawl all the page content that is visible on page load and consider that as the contextual value of the page.
This means that if you're targeting a phrase like "fishing tips", writing blog posts and making new pages about fishing tips with content that is meaningful and helpful to people who are googling for fishing tips is the best thing you can do. If you have keywords & metadata that are relevant to fishing tips it may help a bit, but if your keywords and metadata are deemed "spammy" by Google that can actually hurt you (I.E., if you have "fishing tips" in your metadata on a page that is actually about something else).
Hope this helps
