I know this topic has come up a number of times, so I wanted to share with the group.

I am testing today making the call to action prompt show up with a fixed position (on mobile). Will be interesting to see if there’s an impact in registrations.

```
.signup-cta { position: fixed; bottom: 0; right: 0; z-index: 1000; }

```

Did this work well for you? What were the results?

I like that there’s a question on the metrics. Something we discourse community admins should do more of.

Unfortunately, it seems the change was pretty negligible.  
3.5% increase in registrations from May to July. 327 (July) vs 317 (May). No noticeable impact in PVs per user. Average daily logged in users also went up 2.5%.

I’d be interested in playing around as a variable on how long it takes before showing the overlay. And knowing how many users start the registration process (via Google Analytics event tracking perhaps)

Também usamos esse CTA de sobreposição por 2 semanas e ele aumentou as inscrições em cerca de 5%, o que não é algo espetacular, mas é bom.

Percebi que é um #Contribute > Feature aberto a contribuições da comunidade, conforme mencionado [aqui](https://meta.discourse.org/t/where-to-control-when-the-signup-cta-shows/43047/7?u=pad_pors). Há alguma chance de isso entrar na lista de recursos sérios?
