Hi Kate,
From a quick browse, one slight improvement that you could implement is a template for your title tags and meta descriptions.
Google uses your title tags as ranking signals, and at the moment, yours don't seem to follow any kind of pattern. Best practice would indicate that you include the brand name at the start or the end, and that you could pull in the title of each blog post to use in the title. You should also try to include some sort of keyword for the page in the title if you can.
Although the meta description is not used as a ranking signal by Google, it is one of the first impressions a users gets, so the meta description should be enticing and make the user want to click through to the page.
Hope it helps! Good luck!
