Does Seatext Support Custom Parameters in URLs? Yes — Here’s How It Works

Direct Answer: Yes, Seatext Uses Custom URL Parameters

Seatext supports custom parameters in URLs. When a visitor clicks a link with parameters like ?keyword=, ?utm_campaign=, or any custom query string, Seatext reads that data and rewrites the landing page content to match the visitor's intent. This is how it delivers personalized experiences without creating separate pages for every keyword.

For example, if someone searches "apartment for rent" and clicks your ad, Seatext sees that keyword parameter and instantly adjusts the headline, offer, and CTA to say "apartment for rent" instead of a generic message. The result is a page that feels built for that exact search.

What Are Custom URL Parameters?

Custom URL parameters are extra pieces of data added to the end of a URL after a question mark. They look like ?key=value and can be separated by ampersands (&). Common examples include:

• ?utm_source=google – tells you where the traffic came from
• ?utm_campaign=summer_sale – identifies the marketing campaign
• ?keyword=apartment+for+rent – passes the search term
• ?product_id=123 – custom identifiers for your own use

These parameters are often used for tracking, but they can also trigger dynamic content. Seatext takes advantage of this by reading the parameters and using them to personalize the page.

How Seatext Uses Custom Parameters

Seatext's core function is to rewrite landing pages in real time based on the intent behind each click. It does this by reading the URL parameters that come with the click. Here's the process:

1. Visitor clicks a link – The URL contains parameters like keyword, campaign, or source.
2. Seatext reads the parameters – It identifies the key values, such as the search term or campaign name.
3. AI rewrites the page – Headlines, offers, product blocks, and CTAs are adjusted to match that intent.
4. Visitor sees personalized content – The page now feels built for that specific search, increasing the chance of conversion.

This works because Seatext is designed to read the campaign, keyword, and visitor intent behind each paid click, as stated in its product description. It doesn't just use standard UTM parameters – it can also work with custom query strings you define.

Which Parameters Does Seatext Read?

Seatext is flexible about which parameters it uses. Based on the source pack, it reads:

• Keyword parameters – The exact search term that triggered the ad (e.g., ?keyword=)
• Campaign parameters – The campaign name or ID (e.g., ?utm_campaign=)
• Source parameters – Where the visitor came from, such as Google, Meta, email, or referrals (e.g., ?utm_source=)

You can also set up your own custom parameters. For instance, if you use ?promo=summer, Seatext can be configured to recognize that and adjust the page accordingly. The key is that Seatext reads the URL and uses the values to inform its rewriting decisions.

How to Set Up Seatext with Custom Parameters

Setting up Seatext to use custom parameters is straightforward. Here's a step-by-step guide:

1. Install the Seatext snippet – Add the JavaScript snippet to your website. This usually takes under a minute and works with most CMS platforms like WordPress, Shopify, Webflow, and more.
2. Activate the relevant agent – For landing page personalization, activate the Google Ads Landing Page Agent or the Visitor Source Rewrite Agent, depending on your goal.
3. Define your parameters – In the Seatext dashboard, specify which URL parameters you want it to read. You can use standard ones like utm_campaign or create custom ones.
4. Test and launch – Start with a small set of keywords or campaigns to see how Seatext rewrites the page. Once you're satisfied, scale up.

No programming is needed after the snippet is installed. For most CMS platforms, activation is a simple switch in the dashboard: choose the page, activate SEATEXT AI, and start with a small set of keywords or campaigns.

Key Facts About Seatext and URL Parameters

Limitations and Things to Check

While Seatext supports custom parameters, there are a few limitations to keep in mind:

• Parameter naming – You need to tell Seatext which parameters to read. If you use a non-standard name, you must configure it in the dashboard.
• Single-page apps (SPAs) – If your site is a React or other SPA, you may need additional setup. Seatext has documentation for SPAs, but it's not as simple as a static site.
• Privacy and tracking – Custom parameters can contain sensitive data. Make sure you're not passing personal information that could violate privacy regulations.
• Testing – Seatext uses A/B testing to refine copy, but you should monitor results to ensure the rewrites align with your brand voice.

If you're unsure whether a specific parameter will work, test it with a small campaign first. Seatext's dashboard gives you control over what the AI changes, so you can review and approve variations.

Why This Matters for Your Paid Campaigns

When you ignore custom parameters, every visitor sees the same generic page. That's a missed opportunity. Seatext uses these parameters to make each click feel personal, which directly improves conversion rates. If you're running Google Ads or other paid campaigns, this is a simple way to get more value from your traffic.

Start by identifying the key parameters you already use in your URLs. Then activate Seatext and let it rewrite your pages to match. The result is a more relevant experience for your visitors and better performance for your campaigns.
