How to Use Regex Filters in Google’s Search Console to Optimize Site Performance

Regular expressions (regex) are a pattern-matching syntax that you can use to search for complex strings of characters. Google’s Search Console (GSC) provides the ability to filter and sort search queries and page performance data using regex.

You can optimize your website’s performance by analyzing search data using special regex filters.

The benefits of using Regex in Google Search Console

Regex allows you to read and analyze data without having to rely on the Google Analytics web application or other external tools. Here are the many ways you can use regex to optimize website performance:

  • Build queries to filter pages with the lowest CTR and determine how to optimize them for better performance.
  • Gain insights into the type of searches your pages are triggering, e.g. B. How-to questions, misspelled words, etc. Optimize your site to accommodate these searches.
  • Based on query intent, companies can fill knowledge and information gaps about their products and services.
  • Get as granular as you like with regex targeting specific products or pages. For example, understand the data and metrics of a limited edition offer within a certain duration.
  • Instant results based on previous GSC data, no need to set up filters and wait for targets.
  • Compare and contrast custom results for different datasets to gain further insight into your site’s search performance.

4 Regex examples to help you get the most out of Search Console data

Regex queries only work if your site has significant search impressions from which to glean data. Here are some commonly used regular expressions for manipulating website data.

1. Regex for questions in search queries


This regex string will show all question-related searches your site was shown for. Add more question modifiers like “should”, “would”, “won’t”, etc. to the query to get more results.

Use the resulting data to create short posts targeting Google’s featured snippets section, long blog posts that answer queries with sparse results, understand user intent to click on your site, and inspiration for content ideas.

Sort by click count to find posts with low click through rates to improve the content you provide on these topics.

2. Regex for finding long-tail keywords


This regex string results in searches of six or more words that imply a proper sentence or question.

This regex string results in searches of six or more words that imply a proper sentence or question. You can change the number 5 to any other number to shorten or lengthen the query string to find more long-tail keywords.

Use high-volume, long-tail keywords as H2s in blog posts to boost your site’s search rankings.

3. Regex to match misspelled keywords

Example: Ell?i?(s|z)?(a|e)?(b|p)?eth?

This sample query matches all misspellings and variations of the name Elizabeth. You can create similar regex to find brand related information e.g. B. Misspelling data for common brand names, keyword variations, etc.

A ? after a letter indicates that the letter may or may not appear in the string. Use the or function | to include all possible combinations for commonly substituted vowels or consonants. Add to (?-I) to your query if you want to be case sensitive.

put in front ^ to your query to match or append keywords beginning with your string $ to match keywords ending with your regex string.

Use this helpful testing tool to verify that your regex query is working as intended.

4. Regex to parse subdirectory search data


This sample regex shows the performance of all URLs for a given subdirectory, along with data about the search queries that triggered those results.

Use this query format in conjunction with your URL structure to find data on product groups, product categories, top selling brands, and more.

Copy and save the URL for useful regex queries to run again with a single click.

Optimize your website’s performance with Regex

You can use regex in GSC to analyze query-related data or page performance metrics to improve your site’s search performance. Once you master the art of using regex, use it for other purposes like software testing, HTML form validation, and more.
