Whenever I make any changes, I crawl a few key pages and download the rendered HTML output. You can use any crawler, but I prefer this free one:
HTTrack Website Copier
This gives me a before and after snapshot of the source code, then I use a text comparison application to compare them. This is helpful to point out any accidental omissions or screw ups that might have been committed (e.g., messed up title tags, wrong canonical tags).
Finally, consider installing an SEO plugin, such as:
I'd put this last plugin at the top of the list of must-haves on WordPress.
