What do you like best about Insites?I like the customizability and support from the Insites team the most. They provide live support at all times, and if anything doesn't scan correctly for a report, they investigate and address it immediately. The engineering and product roadmap team is great, constantly releasing new scans based on customer feedback. My favorite is the ChatGPT scan for small businesses, which shows their AI optimization status. The reports are designed well, making it easy for both prospects and sellers to understand the takeaways at a glance. Their integration with tools like Salesforce, Duda Website, and APIs are top-notch. Our sales team loves it because it takes a 10-20 minute research phase and distills it into a single robust report, making our sales reps appear as experts faster. Review collected by and hosted on G2.com.What do you dislike about Insites?I don't want to emphasize this in my review because it's nothing but positive marks from me, but they could make their white labeling settings a little more centralized and easy to set up. We needed a lot of support to get the white label settings fully completed because there are so many of them in different places in the platform. This is very minor and only a factor for a large organization such as ours. Review collected by and hosted on G2.com.

What do you like best about Insites?I like that Insites is really helpful for initial sales scans, SEO optimizations, and reporting. It allows me to show off our product versus competitors during the sales phase and quickly resolve issues for clients during the service phase. I love their fantastic team, who are always available to ensure the tool is as effective as possible. The depth of the scans is very helpful, and the integrations with other platforms make resolving issues stress-free. Setting it up was very simple, and they helped tailor it to fit our exact needs.
