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’vecompiled a comprehensive list. Here are just a few tips for authors, usingSEO across your digital assets:

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

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

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

You can submit keywords with your product data at various online retailchannels. Not all retailers currently accept keywords, but they are beingused more and more. These keywords typically do not appear on-site forconsumers to see, and they are a great way to optimize for terms that youcouldn’t include in the title of the book or the description. Here are somebest 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 blogtopics. Look at the keywords to discover trends in topics that appeal toyour ideal audience. Then, use these topics to develop new blog posts.

Remember, the goal here is not to stuff the keywords into your content, butrather develop helpful, relevant blog posts that your target audience willenjoy. We recommend using your SEO keywords naturally throughout your blogcontent, 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 searchingfor online, you’ll want to incorporate these keywords into your social media profiles and content. Not only will your social media profiles appear on searchengine result pages, but some consumers actually use social media channelslike Facebook, Twitter, Instagram, and Pinterest as search engines, bytyping in keywords to find relevant content and profiles. Use keywordsnaturally in your “about” and “bio” entries as well as in posts themselves,and look for opportunities to use popular hashtags that align with yourkeywords.

5. Include keywords in your optimized website content.

Make sure your site pages and blog posts are optimized for SEO and includethe relevant keywords you’ve discovered. Here are a few places you willneed 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 goalis to build quality links back to your site content. The more quality linksyou have coming to your blog and website pages, the more valuable yourcontent appears to Google, which helps improve your search engine rankingsfor relevant keywords.

Quality link building isn’t easy, but there are a few ways that you canwork 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.
