Hi again!
Different analytic tools might show different results when counting page views and visitors. In a split testing tool, what’s really important is proportions (how many visitors completed my goal compared to the total amount of visitors).
That said, I must admit that I’m surprised with the results being that different. One possible explanation could be, WordPress is counting your visitors twice. When a user accesses the buy page (recorded in WordPress), Nelio redirects it to the alternative version of that page (recorded both in WordPress and Nelio). As a result, you see about twice the visits in WordPress as those you see in Nelio.
If you’re wondering why Nelio’s redirecting visitors in the Buy page, given the fat that this page is not the tested page, but the conversion page, that’s because of Nelio’s “consistency” setting. When it’s enabled, all pages in your site load alternative content. This way, if you changed the title of a page, or the featured image of a post, or anything, alternative content will be loaded everywhere, so that if the tested page is referenced from another page, what you see there and on the actual tested page is “consistent”.
I hope this clarifies all your questions!
If there’s anything else I can help you with, please let me know.
Best,
David
