Before you start using programmatic SEO, it’s important to understand a few basic parts of how it works. Let’s break it down in a simple way with a new example.

Head Terms and Modifiers
Combining the head term with modifiers makes the complete keyword.
A head term is the main part of a keyword — it stays the same.
A modifier is the changing part — it helps you target different versions of the same idea.
Example:
Let’s say we run a travel website & create multiple page for hotel at a time. So, when we use programmatic SEO, it creates keywords like:
- Hotels in Mumbai
- Hotels in Delhi
- Hotels in Jaipur
- Hotels in Goa
Here, “Hotels in” is the head term, and the “city names” are modifiers.
Another Example Could be:
Head Term: Best street food in
Modifier: {city}
Final keywords: Best street food in Chennai, Best street food in Kolkata, etc.
Page Template
The page template has a fixed head term, while the modifier will change based on the search query. The data for the modifier will be inserted from your dataset or database.
And the template can be called the page template, and it’s critical for the process.
Database
Databases store modifiers and other related data points that are used to create pages in bulk according to the design of the page templates. The database can be in various formats, such as a Google Sheets file, a simple CSV file, a database, or an API format.
The number of pages generated through the programmatic SEO process will match the number of rows in the dataset.

How Programmatic SEO Works (Like Mail Merge)
Think of programmatic SEO like Mail Merge in MS Word, where you send personalized emails using one template and a list of names.
Similarly, with programmatic SEO:
- You create one template
- Connect it to a database (with city names, hotel names, etc.)
- And it generates 100s or 1000s of pages — each one targeting a different keyword.
Bonus: If you need to update the info (like hotel prices), you can just update your database, and all related pages can be refreshed quickly. This saves you a LOT of time.
