## **🧭 Open URL Indexer**

In Search Atlas, open **Authority → Indexer**. Select **Index URLs** to submit URLs, or open the available top-up option to purchase additional credits.

## **💳 Buy additional credits**

1. Open the URL Indexer top-up window from the Authority or Billing area.
2. Enter the number of credits you need.
3. Review the total and complete the checkout.

URL Indexer credits cost **$0.10 per credit**. The minimum purchase is **10 credits**, and purchases increase in steps of 10 credits.

## **📊 Understand credit usage**

Each submitted URL uses **1 URL Indexer credit**. For example, indexing 400 URLs requires 400 credits, regardless of how many different websites those URLs belong to.

Purchased credits are added to your available balance and remain there until used. They also stack with the URL Indexer credits included in your monthly plan.

## **🌐 Index URLs from other websites**

You can purchase credits for URLs across different websites, including websites that are not included in your Search Atlas plan. The credit requirement is based on the number of URLs submitted, not the number of websites.

## **🧾 Use existing HyperDrive Credits**

If you have HyperDrive Credits available, Search Atlas applies them toward the purchase first. Any remaining amount is paid through the standard checkout.

## **✅ Check your balance**

Before submitting a large batch, review your available URL Indexer balance in the top-up window. After purchasing, refresh the page if needed, then return to **Authority → Indexer → Index URLs** and submit your URLs.
