A VOSON subscription provides monthly or annually renewed access to VOSON. The Free Tier subscription is included in every user registration, and is renewed monthly at no cost. In addition, monthly and annual subscriptions exist for both the Professional and Premium Tier service levels. Finally, we provide an annual Professional Student subscription, which has all of the benefits of our standard Professional subscription but at a lower cost to students.
The Free Tier is automatically part of every approved new Uberlink registration. The Free Tier includes the latest VOSON graphical user interface, which is supported in Mozilla Firefox, Google Chrome, and Apple Safari (Desktop and Mobile). There is a monthly allocation of 50 VOSON Activity Units (VAU) included (which resets every month), and each account can have a maximum of 10 databases.

The Professional Tier is a paid subscription and includes access to VOSON using the latest graphical user interface, which is supported in Mozilla Firefox, Google Chrome, and Apple Safari (Desktop and Mobile).

Web crawls are given a higher priority than Free Tier crawls. Support questions may be posted in the Community Forum.
The Premium Tier is a paid subscription and includes access to VOSON using the latest graphical user interface, which is supported in Mozilla Firefox, Google Chrome, and Apple Safari (Desktop and Mobile). There is a monthly allocation of 5000 VOSON Activity Units (VAU) included (which resets every month), and each account can have a maximum of 100 databases.. There is dedicated e-mail support and web crawls are given the highest priority (over both Professional and Free Tier crawls).
The VOSON Student annual subscription has all of the benefits of a Professional Tier subscription (see FAQ entry above) at a significant discount. Users must be active undergraduate or graduate students at an accredited institution of higher learning, proof of which must be available upon request. Students should Contact Us directly for further information and to obtain a discount code. Uberlink reserves the right to refuse the use of a Student subscription should proof of a student's active status be unavailable.
For small networks the Free Tier subscription included with every new account should normally be sufficient, and several web crawls of this size can be done with the Free Tier.
This will depend upon the size of the crawled network and upon what kind of analysis you wish to undertake. Although web crawls constitute the largest share of VAU consumption, analysis of large networks will also require a high VAU allocation. A Professional or Premium Tier subscription or (for fixed duration projects) Single Plan will usually accommodate larger networks with more than 10 seed sites.
The monthly VOSON Activity Unit (VAU) allocation for your subscription Tier must be used within its current month--unused balances can't be rolled over to succeeding months.
On the VOSON pricing page you will find all VOSON products, and you can filter the list using the navigation filter above the product display. Also on this page is a product comparison matrix, where you can compare Tier service levels. Clicking on any product will take you to the product's description page, where you can make your desired purchase. Upon a successful purchase your VOSON subscription will be activated--usually within just a few minutes.
