The Slickstream Difference

We sit outside of WordPress, which means when you sign up we build a model of your site and use it to populate all of our search and recommendation tools. Then you pick the ones you want to use, flip a switch, and we’re live! Your site can be running Slickstream tomorrow, with no complicated technical implementation required.

What is Slickstream?

Slickstream is a sophisticated market-leading user engagement suite designed for independent publishers. It helps you turn casual visitors into loyal readers that return again and again through intelligent as-you-type search, content recommendations, favoriting and membership capabilities, email sign-up, and other useful features. You can easily design captivating user journeys that lead visitors to exactly what they’re looking for. The result is higher pageviews, time-on-page, click-throughs, and return visits. As if that isn’t enough, Slickstream’s reporting gives deep insights into its performance and how your visitors are interacting on your site, far beyond what you can see in Google Analytics.

How will Slickstream help me?

Slickstream helps you to get the most out of the traffic that visits your site by turning casual visitors into loyal readers, increasing ad revenue.

Customizable features complement your brand and create a more premium site experience. The powerful recommendation engine serves up the best content to your readers so they spend more time on your site. Slickstream also saves you time, money and hassle from not having to rely on developers, multiple products, or other resources to do a bunch of manual site customization handled with one simple Slickstream installation.

Worried about first-party data? Slickstream helps with that too! Slickstream helps you authenticate traffic and build first-party data with logged-in site visitors.

Slickstream also offers an email sign-up feature that you can use to collect email addresses, but you can seamlessly use your existing email subscription method too. Slicksteam’s Highlighter feature draws attention to any element of your site you choose and has proven to significantly improve conversions.

Do You Support Languages Other Than English?

Yes we do. Our underlying recommendation technology is not English-specific, and we have already localized the Engagement Suite for German, Portuguese, Spanish, Dutch, French, Norwegian, Swedish, Croatian, Russian, Danish, Arabic, Hebrew, Japanese and more. Reach out to us and we can confirm if we support your language too.

Slickstream has great search functionality of course but the ability to favorite is awesome as well. Recommendations are spot on. The analytics are way cool; in fact, I use them just as much, if not more, than Google Analytics. Best of all the support is amazing and they are willing to configure just about everything to exactly how you want it. Cost is reasonable too. An easy 5 stars for this one!

I had Slickstream and then moved away from it. The service I went with didn’t do a great job on recommendations and in some cases made no sense. Slickstream made it so easy to reconfigure my site exactly the way I wanted and I love the analytics that I have concerning searches on my site.
