How to Write a Tagline for Your Book (And Why You Need To)

Okay, how many of you don't know the difference between a logline and a tag line? *raises hand* Yeah, me too. But lucky for us my friend Marcy Kennedy is here to explain. And wow, there is a BIG difference!

As you read on you'll notice below Marcy's also running a webinar on pitching. If you have not yet taken a WANA International course, I wholeheartedly recommend them and Marcy, who is smart and savvy! (Full disclosure--I have taught webinars myself through WANA, and I love the spirit of community and their mission to help writers. Plus the online classroom Big Blue Button Technology can't be beat as a tool for learning!)

Also, if you'll indulge me a bit further as I so rarely openly endorse like this, I would be remiss if I didn't also mention WANACON coming in October. I attended the last online con, and unfortunately I am out of town for this one, but trust me, it is going to be amazing. You can't get this level of instruction and expertise for the price anywhere else.

*meep-meep*  Okay, turning things over to Marcy!

As writers, we hear about loglines all the time—how to write them, why we need them, when to use them. And so, when we hear about this thing called a tag line, it’s easy to make the mistake of thinking tag line is just another name for a logline.

It’s not and we need both because the tagline is what goes on your book cover.

 A logline tells you what a movie or book will be about—the main conflict, the main character, and the stakes.

 A tag line is a catch phrase. It doesn’t tell you anything specific about the story, but it does give you a feel for it in a way that a logline can’t. A tag line is what you see on movie posters.

To help you see the difference between a logline and a tag line, let’s go through examples of both.

Lord of the Rings 

Logline: A young hobbit needs to destroy an ancient, powerful ring before the evil overload consumes the world in everlasting darkness.

Tag Line: One ring to rule them all.

The LOTR logline gives you the main character (a hobbit), the main conflict (the hobbit wants to destroy the ring and the evil overlord wants to keep the ring), and the stakes (all the good in the world will be destroyed).

The tag line gives you the emotional feel of the book. It will be dark and serious. You could probably even guess that it will be an epic fantasy.


Logline: A sheriff must find and kill a man-eating and frighteningly intelligent shark before it murders again and scares away all the tourists who support his beach-front community.

Tag Line: Don’t go into the water.

Do you see how the tag line doesn’t really tell you anything about the movie? Based on just the tag line, Jaws could be about poisonous jelly fish or a deadly current. It’s not meant to tell you the plot. It’s meant to evoke emotion. It sets the tone for a story that’s going to scare you. You know it’s going to be either horror or a thriller.

When you’re writing your tag line, ask yourself what tone you want to set for your book. What emotions do you want to evoke?

Now brainstorm 5-10 possible tag lines, trying to keep them under 10 words each. If you want, share your attempts in the comments, and give feedback on the attempts of someone else!

Thank you for that clarification, Marcy, and to Angela, for bringing this to my attention. Excellent, short definition of both! Easy to remember, and with the number of things I have to remember, the easier, the better.

Bish Denham said...

Okay, I definitely learned something new today!

Angela Ackerman said...

This really made me see the power a tag line has, and why we should work so hard to craft just the right one. I think it makes a huge difference to drawing the reader in. :)

Thanks for hanging out with us today, Marcy!


Marcy said...

Thanks for having me here, Angela! As an avid Bookshelf Muse fan, it's an honor to be posting here.

@M.L. - I agree. The easier we can make this, the better and more likely we are to remember it when we need to.

@Bish - Glad I could help :)

Patti said...

Thanks for this, I was one of the people who raised my hand at the beginning. Now I can put it back down.

Natalie Aguirre said...

Thanks for the tips, Marcy. I didn't know the difference. Loved your examples.

Deb Salisbury said...

I didn't know the difference, either. Great tips!

Becca Puglisi said...

Marcy, this information is really really useful. I had no idea there was a difference between tag lines and log lines. I love learning new stuff :). Thanks for being here!

Marcy said...

Patti, Natalie, Deb, and Becca - I'm glad I was able to sort it out for you. They're both great tools once we know how they're supposed to be used.

Jessica L. Brooks (coffeelvnmom) said...

Love this post! Marcy, you make it look so easy! :) I was trying to write one yesterday and ended up doing the whole *head desk* thing and giving up! Glad to know the difference between tag and logline... very informative! (Do freelance writers allow you to hire them just to write those? Ha ha. Just kidding.)

Karen McFarland said...

Marcy, you are a really good teacher. You have a way of simplifying a task in order to make it understandable. "Don't go in the water." Got it. It says enough without giving away the plot. I will bookmark this post just in case a miracle happens and I actually publish something and need a tagline. lol. :)

Pen N. InkBlog said...

Thank you Marcy. Beautifully defined.
I'll start thinking about that.

Empty Nest Insider said...

I came over from Susanne's blog, and I'm glad I did! I never heard of a logline before. Thanks for the great examples of tag lines. I agree that they are a great way to lure readers in.


Marcy said...

Jessica - I hope this saves your head from any more contact with your desk :) I don't write them for people, but I have consulted to help writers polish their pitches.

Karen - Thank you. I think that's one of the nicest compliments.

Pen N. Ink & Julie - Glad I could help!

Stina Lindenblatt said...

Love tag lines. Just can't write them. :P

Rosemary Gemmell said...

Great definitions - thank you!

Karen Lange said...

Thanks so much for the info! Appreciate your insight.

Lori Schafer said...

Thanks, Marcy. I absolutely did have the two concepts confused!

myriteofpassage said...

Thanks for the great tip, Marcy. It's fun to practice too ... getting the knowledge into the cells. More great value, Bookshelf Muses :)

Unknown said...

Hand raised here, too, for not knowing the difference. For me the tag line for my Underdead books came easily--it's the distillation of the latest book's plot into the logline that's the head-against-the-wall-banger. OW!

Not Undead, merely...UNDERDEAD.

Marcia said...

Wonderful examples. Tag lines are so tough, but fun!

Tracy Campbell said...

Angela, so glad to see smart and saavy, Marcy share the differences between a tag and a log line. I hate to admit this, but I didn't realize the difference, but now I do. And Marcy, the examples were perfect. :-)

I have been struggling with a tagline for my author website. Maybe it is too early in my career to define myself with a tagline--I've only written one book.

What is your take on author blogs or websites having taglines?
