Q: How much does it cost?
A: As of now, Outlink Counter is in beta and the only plan is a free tier. Keeping a generous free quota is one of the highest aims of this project, even if paid plans were to be implemented some time in the future. New sign-ups might be temporarily disabled as the load reaches server capacity limits.
Q: What are the limitations?
A: Currently each account may save up to 1000 different links and 10000 clicks over a period of 28 days. This amounts to around 350 link clicks per day. Data older than 28 days is deleted and frees up quota. It is intended to raise these limits as server capacity increases.
Q: Can I just use Google Analytics / Matomo instead?
A: Yes, both of them are capable of counting external link clicks. Outlink Counter excels in ease of integration and ease of sharing. In case you do not wish to share statistics or already have one of the mentioned services in place, you are probably better of relying on them.
Q: How does it play with URL shorteners?
A: URL shorteners typically require shortening and replacement of links on the site in order to count them. The upside of this is that adblock cannot affect the counting. Downsides are that links often have to be shortened manually and that outlinks will stop working if the service is down.
Q: How does it play with Wordpress?
A: The Wordpress ecosystem features a bunch of plugins to achieve the tracking / counting part of Outlink Counter. This method is preferrable as it uses internal mechanics and data never leaves the server. If you do not plan to use the easy sharing feature of Outlink Counter you should stick to those plugin. They can for example be found via Google searches for "wordpress outbound link tracking".
Q: What about paid plans?
A: After a successful beta phase paid plans will be implemented. This will not change features of the free version (limits may even increase due to better infrastructure). Paid plans will come with new features like external link autodiscovery (via crawler), automated white-labelled email reports and translations.
