eBibleStudy.org is an excellent resource for biblically accurate information. On the site, you’ll find a collection of free Bible study lessons designed for adults or teenagers, written by Bible professors from Oklahoma Christian University.

BibleGateway is my go-to source for a reliable audio Bible. I use it daily and highly recommend it to all my family and friends. Also, I use it for quick reference work, but beyond that, I don’t know much more about the site.

BibleStudyTools.com is the largest free online Bible website for verse search and in-depth studies. I use it daily for looking up scripture in the interlinear Bible and Strong’s Concordance. 

Bible Hub is a great resource for serious Bible students. You’ll find a variety of Bible versions, a Greek/Hebrew Lexicon, Strong’s Concordance, and much more.
