What Are Semantic Keywords?
Semantic keywords are words or phrases that are conceptually related to a given keyword or topic. For example, “italy” and “dough” are semantically related to “pizza.” It’s important not to confuse semantic keywords with target keywords (keywords you want to rank for).
For example, you might want a page to rank for “pizza dough recipe” and related keywords like “how to make italian pizza dough.” But you wouldn’t really want it to rank for “italy.”
Why Use Semantic Keywords in SEO?
Semantic keywords help search engines understand your content’s subject matter, scope, and depth. And that can help you rank more prominently for relevant queries. This is because Google uses semantic search (not keyword search) to find search results. In other words, Google doesn’t just look for the user’s search terms on your page. It tries to match the meaning of the query with the meaning of your page.
For example, Google infers that people searching for “authentic pizza dough” want Italian-style recipes. And infers that pizza recipes containing terms like “rustic Italian” and “Neapolitan style” are relevant.
Google performs semantic analyses with the help of various systems, such as:
- Google Knowledge Graph: A database that maps relationships between people, places, and things
- Natural language processing: A form of artificial intelligence that helps computers interpret human language
When you optimize your content for these systems, you’re doing semantic SEO.
How to Find Semantic Keywords
Once you’ve chosen a keyword or topic to base your content around, look for semantically related keywords. Because they’ll help you create relevant, information-rich content that’s easy for users and search engines to understand. Here’s how to find semantic keywords:
Google Search
You can often find semantically similar keywords on Google’s search engine results pages (SERPs). Pay particular attention to the following elements (when they appear):
- Autocomplete suggestions: Look at the autocomplete suggestions that come up as you type your query into Google
- Related searches: Google may display related search queries that allow users to refine their search. These can provide great inspiration for semantic keywords.
- Bolded terms: In addition to bolding the search term used, Google may also bold related terms that appear in snippets
- People Also Ask: The People Also Ask (PAA) box is a SERP feature (an additional element in search results) that contains popular questions and answers from across the web. This can be a great source of semantic keywords and question keywords.
Google Trends
When you explore a subject in Google Trends, you can find related topics and search terms. Which you can use as semantic keywords. Head to Google Trends, enter a search term, and choose a result from the list:
Then, select the region and time range you want to explore. (You can also change the category and search type, if you wish.)
Scroll down to the “Related topics” and “Related queries” sections. “Rising” topics and queries are those that have had the biggest relative increase in search popularity over the selected time range. Switch to the “Top” results to see the most popular related topics or queries. The most searched result gets a score of 100. And the others are scored relatively (e.g., something with a score of 50 was half as popular).
Keyword Planner
Google Keyword Planner is a free tool that lets you find keywords for paid search ads. But you can also use it to find semantically related keywords. Visit Keyword Planner and click “Discover new keywords” to get started. Then, enter your target keyword(s) and click “Get results.” The tool will present a list of keyword ideas. And in the “Refine keywords,” section, you’ll find common term categories. Expand these categories to discover the specific terms to get inspiration for your content.
