I have 10 core products, lets call them A to J.  My old website had a page for each but I wish to consolidate them as the user experience is not great as many of the products are related.

My new site will give products A to D each their own page as they're big independent sellers and have lots of bespoke info for each.  I wish to put E to J on a single page as they're related so the user scrolling through them all will be the best experience.

My question...on the index page, I wish to have an image and link for each of the 10 products.  E to J will now all link to the same page.  Is using an anchor still best practice so the user arrives at the correct part of the page?  Or do I just put them at the top of the page for them to scroll down and see all that is on offer?  I could potentially even work out how to re-order the page so when the user clicks on a link, a parameter in the link will use a PHP script to put what they want at the top...or is that overly complicating it and potentially ruining SEO?

You won’t know until you test.

This is one of those things that might work or might result in fewer sales, nobody will know until you launch.

As to SEO. Combining products on one page is not good. Google prefers individual pages.

Thank you.  Are anchors still widely used to jump to relevant sections of another page?

Sometimes. Depends on the context.

What doesn’t work is linking to an anchor from a different page. The whole UI/UX gets messed up and people get annoyed.

In general, try to avoid using them.

How many sites do you see that still use them?

Which is what I am proposing.  I'll work out a better way as my suspicion was that it's not a good idea.  Thanks
