Plans, Pricing & Payment

  • What is the difference between free and paid subscriptions?

    The serpstack Free Plan is a way of getting familiar with the API, offering basic API functionality and a limitation of 100 monthly searches.

    As soon as you need a higher volume or advanced API features, you can choose from one of the premium subscriptions or contact us for a custom solution.

  • Which subscription plan fits my needs?

    The most decisive factor when it comes to your technical requirements is the number of monthly SERP API requests you need per month. Other factors include HTTPS encryption and access to search engines other than Google.

    Signing up for the Free Plan is a great way of getting to know the API and implementing it without any commitments.

  • Which payment methods are supported?

    Payments can be made via credit card (Visa, MasterCard, Discover, Diner's Club, American Express). Enterprise and high-volume customers may request annual bank transfer payments to be enabled. You can change your payment method at any given time in the "Payment" section of your account dashboard.

  • Can I also pay yearly?

    Yes. If you choose annual billing, the total price of your subscription plan will be up to 15% lower than the total amount you would pay with a monthly payment frequency.

  • How can I change my payment frequency?

    In order to change your billing frequency from monthly to yearly or from yearly to monthly, you will be required to downgrade your account back to the Free Plan.

    Step 1: Navigate to the Subscription page, click "Downgrade" in the Free Plan section and confirm your downgrade. Downgrades are not effective immediately, your premium subscription will remain active until the end of the current billing period.

    Step 2: Once your billing period ends and your account downgrade has become effective, navigate back to the Subscription page and click "Upgrade" in your preferred subscription plan's section. You will now be aked to choose a new billing frequency.
