Looking for a general "blog health" check

Hi experts,

I've been blogging for over 15 years using a self-hosted WordPress plateform. I'm not really monetizing the blog, it's mostly my portfolio and I focus on content creation.

Fifteen years is... ahem, a long time. Many things changed and I'm not exactly on top of latest dos and donts. The blog is fully functional but I'm sure it would benefits from a good cleanup and a fresh pair of eyes.

So I'm looking for someone to:

• Clean up old tables
• Perform a quick SEO check...
