What do I know???

It's my turn to teach you all something, beloved Seekervillagers.I want to talk today about marketing. One aspect of it, becaue if I think of TWO things to talk about...I'll save teh second one for next time.
Keep in mind I barely know what I'm doing.
Teaching isn't my greatest gift....and that's sad cuz I was a teacher for eleven years.There is actual paperwork on file proving people often are dumber after I've tried to teach them something.It's notarized!!! There's the disclaimer, so now I'll tell you something I learned self-publishing. 
I'll begin with this...I have never loved my publisher more. It is interesting and challenging and humbling to try and do all the jobs Bethany House has been doing for me over the years.
I'm trying to figure out how to market my books.I really have no idea.Send out a newsletter and post to social media. What else? As my great attempt at marketing I bought an Amazon ad because I was told they are so easily tracked to see if they worked.
Except I did it and have no idea if it worked.Whatever tracking I can do, I can't do. When you're self-publishing EVERYTHING IS YOUR FAULT!!
But on the other hand, I can't tell that a single person bought a single book due to my ad.On the Other other hand, I'm not sure the ad is running yet.
So anyway, I go to marketing sessions at writer's conferences because FRANKLY those are the classes they offer to people who have books in print.
I often ignore them and go to more basic classes hoping to learn how to write.But I have to sneak in.
So I bought the ad.I have a professional editor and book cover maker and formatter.
I am trying to figure out where to go indie-publishing-wise after these five books come out.(I've got an idea)And in the meantime, I'm floundering.
Has anyone, by any chance seen an ad for my books...anywhere?I sure haven't.Tell me what I should do about marketing. (Oops, I just slipped away from teacher and turned to asking you to teach me!!!) What works? Have you ever seen an ad that made you click on a book?A blog post?A book reviewers blog? I have considered giving away the first chapter free..........but I don't know how. Still........that's in the List of Ideas folder.Help me!And ask me questions, too. Heaven knows if I can help you, but I'll try.And maybe we can help each other!Today I'll draw two names from the comment section to win a copy of one ebook, Loving the Texas Lawman and Loving Her Texas ProtectorTwo ebooks. Two winners.Also available in print versions.
