September 26, 2018  •  Jessica Johns

In today's digital age, it's important to find new ways to reach your audience online.

Search engine optimization (SEO) is a process that helps you optimize your content for search engines so you have a greater chance of appearing in the top results for relevant search terms. From your book description, to social media profiles, to your blog and author website, having a basic understanding of SEO will help you improve your content and increase discoverability and reach.

Incorporating SEO keyword tools into your book marketing strategy is a vital part of improving SEO. Getting to know keyword tools and strategies can help you understand how consumers search for books, their favorite authors, and related topics. You can also identify consumer keywords, topics, and phrases to inform content marketing and advertising campaigns.

Below, we’ll cover a few of the paid and free SEO and keyword research tools that help find the right keywords to reach your audience. We’ll also give you a few tips on how you can incorporate these keywords in your title data, author blog, social media marketing, and other book marketing strategies to expand your reach online.

SEO Keyword Research Tools for Book Marketing

We’ve put together a quick list of SEO keyword research tools that you can use to find the right keywords for your book marketing. This is by no means an exhaustive list, but it’s a great place to get started.

As you use these tools, remember that your goal is to find keywords to align your book and author profiles and pages with real people—providing context they care about in a way that will resonate with them. You don’t want to game the system. Keywords should always be relevant to your audience, to the content of your book, and to the topics and interests that you write about.


Go directly to the source to research what potential buyers are searching for, what they’re ultimately clicking on and buying, and how they describe your book or comparable titles.

  • Type your book’s topic, genre, or theme into the search bar to see top auto-complete suggestions.
  • See which titles are at the top of related search results.
  • See who is buying ads for your target keywords.
  • Look at what titles are ranking in what product categories.
  • Read book reviews to identify the words and phrases readers and fan use to describe books.
  • Use Advanced Search to filter search by author, keywords, category, pub date, publisher, and more.

You can also see if your book is indexed by Amazon for a specific keyword. Being indexed means Amazon understands a book to be relevant for a keyword or phrase and has tagged and linked them together appropriately. By searching for the ISBN or ASIN (Amazon’s unique product ID number) with a plus sign (+) followed by your target keyword(s), you can make sure that you’re optimized for Amazon.

However, it’s important to note that being indexed is not the same as ranking in search results. You can be indexed and still not rank highly, and it’s also possible to not be indexed and still rank.

Google Trends

With Google Trends, you can enter up to five search terms or topics to see:

  • Relative search volume and popularity
  • Seasonal shifts and trends
  • Regional interest
  • Related topics and searches

Google Trends data is anonymized and indexed (dating back to 2004), so you can see how search habits have changed over time and where there is meaningful interest and activity.

Google Trends is a great starting point for understanding search trends and consumer interest in different types of books, genres, authors, and other topics that might align with your work.

Cost: FREE - making it a great tool to add to your SEO keyword toolkit.

Google Keyword Planner

Google Keyword Planner is Google’s official keyword research tool. It is intended for use with AdWords but can also be used on its own to find keywords, number of average searches per month, and competition difficulty. You can even create a keyword plan right in the dashboard, to save it to your account or share with someone else.

Cost: You can create a free account to use this program, and there is no cost to search outside of AdWords. You may be asked to enter credit card information upon account setup, but you will ONLY be charged if you run an AdWords campaign.

Keywords Everywhere

Keywords Everywhere is a browser extension tool that requires registration with a free API key. You can install this extension for Chrome or Firefox and get an API key. Once installed, Keywords Everywhere automatically embedskeyword search volume and competition data within supported sites and tools. So, you can see estimated monthly searches and more, populated in search engines like Google, Amazon, and YouTube as well as within other keyword tools like those covered here.

Clicking the extension icon in your browser toolbar will also give you additional options to get metrics on uploaded keywords, or to see a keyword density analysis for a webpage.

LibraryThing is a Wikipedia-like community and cataloging site for books where users can tag, review, and add detailed data about books and authors.

Use the “Tagmash” feature to find comparable titles based on similarities in genre, content, tone, and style. List a few key aspects of a book to find other books with those attributes – rhyming board books about trucks or urban fantasy featuring witches and demons. Advanced operators (using minus “-“ to demote and double minus “--“ to exclude titles tagged with a particular term) let you further refine and filter your search (ex: books about vegan nutrition, but that aren’t necessarily cookbooks).

Cost: FREE - conduct unlimited searches with a free account. (As a bonus, if you join LibraryThing, you can add and update information about your own books, too!)

You’ve Got SEO Keywords, Now What?

Now that you have the tools you need to get started with keyword research, let’s talk about what you should do with those SEO keywords after you’ve compiled a comprehensive list. Here are just a few tips for authors, using SEO across your digital assets:

1. Use keywords in book title, description, and other descriptive product metadata.

Use relevant consumer keywords, topics, and phrases in your book description as well as in your title, subtitle, series name and other descriptive elements whenever possible. Make sure the first 25 words of your description include the most relevant keywords that potential buyers might be searching on to find your book.

2. Submit retailer search keywords to improve search optimization and categorization at Amazon and other online retailers.

You can submit keywords with your product data at various online retail channels. Not all retailers currently accept keywords, but they are being used more and more. These keywords typically do not appear on-site for consumers to see, and they are a great way to optimize for terms that you couldn’t include in the title of the book or the description. Here are some best practices when it comes to submitting search keywords:

  • Use at least 7 keyword phrases (the more the merrier – submit as many as you can).
  • More specific and detailed keyword phrasesare better than single words, helping you incorporate a broader range of keywords that highlight the breadth and depth of interest about the book.
  • Put the most relevant and important keywords first.
  • Use keywords that are complementary but not duplicative of terms used in the book description or elsewhere. (So, no need to include the title or author name in your retailer keywords.)

3. Use keywords to develop new blog topics.

Your list of SEO keywords is a great place to start when planning new blog topics. Look at the keywords to discover trends in topics that appeal to your ideal audience. Then, use these topics to develop new blog posts.

Remember, the goal here is not to stuff the keywords into your content, but rather develop helpful, relevant blog posts that your target audience will enjoy. We recommend using your SEO keywords naturally throughout your blog content, while addressing the larger blog topic.

4. Incorporate keywords in your social media profiles and content.

Once you have a list of relevant keywords that your audience is searching for online, you’ll want to incorporate these keywords into your social media profiles and content. Not only will your social media profiles appear on search engine result pages, but some consumers actually use social media channels like Facebook, Twitter, Instagram, and Pinterest as search engines, by typing in keywords to find relevant content and profiles. Use keywords naturally in your “about” and “bio” entries as well as in posts themselves, and look for opportunities to use popular hashtags that align with your keywords.

5. Include keywords in your optimized website content.

Make sure your site pages and blog posts are optimized for SEO and include the relevant keywords you’ve discovered. Here are a few places you will need to use the keywords:

  • Headings: Your keyword should be used in the H1 (or title) as well as in at least one of your sub-headings.
  • Content: Use the keywords logically throughout the content. There is no longer an ideal ratio for keywords, but you don’t want to “stuff” your content with keywords. Instead, write page content that incorporates the keywords naturally.
  • Meta Description: The meta description is a short blurb describing what your page or post is about. Be sure to use keywords naturally in this description.
  • Image Tag: You should also include an image tag for any of the images that you use on the page. This is another opportunity to use your keywords.

6. Look for link building opportunities.

Link building is an important part of search engine optimization. The goal is to build quality links back to your site content. The more quality links you have coming to your blog and website pages, the more valuable your content appears to Google, which helps improve your search engine rankings for relevant keywords.

Quality link building isn’t easy, but there are a few ways that you can work to build links back to your SEO keyword optimized content:

  • Guest Blogging: When you write and publish a guest blog post on another site, you have the opportunity to link back to relevant pages on your site or blog, while also reaching a new audience online. Find relevant blogs or sites that accept guest submissions and look for opportunities to write about relevant topics.
  • Link Exchange: In addition to building links back to your own site, you should also link to relevant external content on your blog posts and site pages. Once you have linked to another article or site, reach out to the author to let them know that you’ve linked to their content, and ask if they could link to yours.

  • Posting Links: Look for opportunities to post links to relevant content on online forums, group discussions, or social media posts. Make sure the content is relevant to the initial discussion topic as you want to be helpful, not spammy.

Key Takeaways

If you want to reach your audience in the digital age, you need to improve visibility on search engines and online platforms like Google, Amazon, and Facebook. One of the best ways to do this is to find and incorporate SEO keywords into your book descriptions, web page SEO, author blog, social media marketing, and other online marketing assets. You can get started finding the right SEO keywords by using the keyword research tools listed above.

Once you have a list of relevant keywords, it’s time to incorporate these into your book marketing strategy. Use the keywords to develop the types of content that your audience will be searching for. The more quality online content you produce that’s optimized for SEO, the better your chances will be of reaching and connecting with your ideal audience online.
