Comparison pages are excellent for SEO, but they usually don't bring much value to readers.
If these visitors want to know how your product is different from your competitors', chances are they're already using one of those alternatives.
One way to make your comparison page more actionnable is to use it to explain them how they could easily switch from their current alternative to your product by importing their content.
Depending on the difficulty of the migration, show them a simple step-by-step tutorial or offer your help to import their data.
