Great question! I've been working in the SEO industry for over 13 years, so I'm happy to help if you want some guidance.

I'm a fan of Search Engine Land's daily email newsletter, but the best way to get a steady stream of SEO tips is by following top SEOs on Twitter and LinkedIn. Every time I read an article or watch a webinar with someone in the SEO industry that's new to me, I immediately follow them on social media. Here are a few:
Joe Youngblood @YoungbloodJoe
Andy Crestodina @crestodina
Aleyda Solis @aleyda
Brian Dean @Backlinko
Neil Patel @neilpatel
Barry Schwartz @rustybrick
Danny Sullivan @dannysullivan

And follow the big players like SEMRush, Search Engine Journal, Search Engine Land, Google, Bing, Moz, and the like. They are always posting tips.

Hope that helps! Feel free to reach out if you'd like learn a bit more about SEO.
