About Us

GrepWords is your source for keyword data at scale.

GrepWords was founded in 2013 by Russ Jones, a true pioneer in data science and SEO. Russ was a self-taught data scientist, who made a big impact in the industry through his work at Moz and here at GrepWords.

MarketMuse, a leading content intelligence and strategy platform, acquired GrepWords in 2020. Tragically, Russ passed away in 2021. Our goal is to honor Russ and his vision by adding value to the community, growing the GrepWords platform and building upon the legacy Russ leaves behind while honoring his vision and work in everything we do.

In 2021, GrepWords launched its updated platform, focusing on Keyword and SERP intelligence data and reports. GrepWords is growing, keep an eye on this site or follow us on Twitter to stay in touch and up to date.

Here’s a few things you can expect coming soon from GrepWords:

  • Intelligence Reports: Understand the competitive landscape for your industry of interest with details on ranking domains, visibility, market share and valuable keywords.
  • Scraping Endpoint: Scrape the content of a page and receive back HTML and structured JSON. Use this tool to analyze page content, store the text of a page, compare pages within a SERP and more.
  • Knowledge Graph Endpoint: Query via the API and get back related topics, content scores and word count targets for your key term.


We do not have a free trial. However, we do offer these example datasets:

  • Keyword lookup
  • Related keywords
  • SERP endpoint

If you’re looking for a custom solution, jump on a call. We can provide additional sample datasets as needed.

A rate limit is how many times you can call the API over a set period of time, in this case, a one-month period. Rate limits on our standard plan are as follows:

  • 100k SERP requests
  • 1 million keyword lookup requests
  • 1 million rows of related keywords

If you need more, additional requests can be purchased at a rate of $100 per 100k SERPs or 1 million keywords. If you anticipate needing this upgrade regularly, you may qualify for a 10% discount. We can also discuss a custom plan to ensure you always have access to the data you need, when you need it.

SERP: 50 requests per minute

Lookup: 500 requests per minute

Related: 15 requests per minute

If you require higher rate limiting please reach out to us to discuss your options!

Our standard, self-serve plan is month-to-month with no contract term required. If you partner with us on an enterprise solution, we work off of annual contracts.
The standard GrepWords plan pulls from our keyword database, while all SERP requests are live. We can provide live keyword data as part of an enterprise-level custom solution. If you’re interested in discussing a custom solution, we can walk you through use cases or design something specifically for you. Set up a call to learn more.
Requests typically resolve in 1-10 seconds, depending on the endpoint.
For our standard plan, most major credit cards are accepted. If you’re partnering with us on a custom solution, we can accept credit card, ACH and check payments.
Your unused API credits are refundable during the first 30 days.

GrepWords is based in the United States, headquartered in Boston, MA.
