How many internal links do you think there are likely to be in a WooCommerce site with approximately 400 products? I knew there would be several times that number because each product page is accessed in a number of different ways. And then there are the articles, 43 articles currently. And then there are the product images and the links to the thumbnails and the main product images on the individual product pages.
Still, when I just scanned Flying Twigs with Sitebulb Pro, I was surprised at the number of internal links, which is currently 63,370. And that just goes to show how many internal moving parts there are to a website.
