Slickstream Favorites and Email Address Collection
Slickstream's favoriting system allows your visitors to show their appreciation for a post or page and also allows them to build and store a list of their favorite posts on your site. You can read more about it here. This system also serves as a membership system and can be used to increase the number of email addresses you collect from your visitors.
As a publisher, you can choose whether your visitors must sign in before they can favorite a post. This setting is in the config tab in your portal.
Sign up not required option:
The default setting is that your visitors are not required to sign in to build their list of favorites. In this mode, their favorites are stored in their browser storage so that their list is available to them whenever they return to your site using that browser. The downside of this, is that if they want access to their list from another device or browser it won't be available.
They do however have the option to sign in to "Protect your favorites". In doing so, they create an email/password combination that they can then use from any device or browser to view their list. You can also customize the messages your visitors see as they go through the sign up flow and the default state for the "Notify me" checkbox. See the screenshot above.
Sign up required option:
If you change the setting to "Require sign-in to favorite" then whenever a visitor favorites any page or post, a dialog box will pop-up requesting they sign-in before doing so.
All email addresses collected during the sign-in process are visible and available for download in your portal under the Membership tab. If you set up an integration with your Mailing List Management provider then all the email addresses collected can be automatically added to your mailing lists.
Which mode is right for my site?
The trade-off is very simple. With the default setting, there is no "friction" in the favoriting system and, thanks to the playfulness of the fluttering hearts, we see very high (~5% of page views) favoriting rates. However, far fewer visitors sign in, as for most, storing their list of favorites in browser memory is sufficient and they have no need to sign in. Which in turn leads to far fewer email addresses being collected.
Conversely, if you "require sign-in to favorite", the favoriting rate will drop substantially but you will collect many more email addresses.
So, it really comes down to what you value more: high favoriting rates or more email addresses.
With the advent of the potential importance of email addresses and the part they play in so called "first party data collection" forcing visitors to sign-up to build their favorite lists may well be an appealing option. For publishers using the Mediavine ad network, Slickstream directly integrates with their first party data API to leverage any potential ad revenue benefits of visitors that sign-up/sign-in. However, it's worth stating that collecting email addresses by any means is a difficult challenge. You can read more about Slickstream and first party data here.
Remember that you own all data that Slickstream collects, and it's yours to use as you see fit. Do keep in mind that when sharing that data with a third party you may have some privacy responsibilities to consider depending on the end application. Depending on how you use your data, you may want to customize the opt in message for your visitors. This is easy to customize as part of the sign up flow. See the screenshot below that shows where you can customize this particular text and this article describes how to customize all of the sign up flow messages.
Lastly, remember that you can change the mandatory membership setting at anytime without losing any addresses you have collected previously, so the best way to work out what is best for you may be simply to experiment.
