Given at ad:tech Asean 2015 http://www.adtechasean.com/ July 8th in Singapore by MWI's CEO Josh Steimle @joshsteimle, who is typing this, so I'll break out of the third person.
I was assigned this topic, and it was a fun one. I love being able to give actionable tips, and this deck includes 10 of them--all free or very close to free. Most not all that time consuming either. Ranges from basics like "Get a mobile friendly site already!" (with some more details on how) to how to come up with ideas for blog posts. Oh, and of course, you can't leave out HARO (Help A Reporter Out).
