What do you like best?
The best aspect of Leadlander is being able to track individual users who come to your site and see what pages they have been to. If that user is known in your database as related to a specific email, then it will track them over time to see what their activity is. You cannot do any sophisticated reporting in this respect though, just lists of page visits and dates, and form submissions if you have them enabled to work with Leadlander. The lead scoring aspect is somewhat useful if you have no other way of tracking this in your CRM, but really does not fill in all the gaps.
What do you dislike?
A lot of things. Leadlander's UI is far out of date. It feels like it was developed in 2000 and then was never updated. Reporting is pretty basic, and it is difficult to associate the data they collect with your CRM other than manually or possibly with Zapier.
From a prospecting point of view, you get a decent list of companies who have visited your site, and that list is more accurate than Hubspot's prospecting tool, but less accurate than Lead Forensics. Lead Forensics filters out the user's ISP, so you will only get the actual company you are looking for, instead of 20 visits from Rogers that is probably someone's ISP instead of their company - but you definitely pay for it with Lead Forensics.
Recommendations to others considering the product
You need to understand what you are looking for from your goals. They are a yearly subscription, so it is best to do the trial and see if the interface, information, reporting, and integration capabilities are what you're looking for. If you are looking for something cheaper, Hubspot sales pro offers a slightly less robust prospecting tool with a great sales outreach automation set of tools that is worth the minimal monthly cost. Or you can look at Lead Forensics for a more modern and robust set of prospecting tools, though they are probably twice the annual cost of LL.
Do not get this product - or any lead prospecting product - if you do not intend to use the features. It is a wasted investment if all you want to do is look at the company names coming to your site. As with any tool, unless you take action and have solid, actionable outreach campaigns that make use of it, you won't see any valuable return.
What business problems are you solving with the product? What benefits have you realized?
I work for a B2B company, so knowing the companies of our visitors is important in directing our marketing and outreach campaigns to the right locations and industries. The business problem we have is associated with lead scoring and associating behaviour on the website with individuals to help us with more targeted and relevant outreach.
