After your WordPress theme is installed, I recommend making sure the default URL of your website drops the "www" before your site URL. You may have noticed that Google stopped displaying the "www" in the site navigation bar in the Chrome web browser.
This will bring you from a URL that looks like https://www.yourblogname.com over to a more simple https://yourblogname.com.
You can change this quickly by going to Settings > General and double checking that there's no "www" in the "WordPress Address (URL)" and "Site Address (URL)" fields:
All of the pages on your blog will now be redirected automatically to the version without the www, which looks much cleaner and tends to feel more trustworthy to readers.
