Categories and tags across pages

Hello...can anyone here tell me if you have come across a way to complete the tasks here in the view link below.  I'm trying to accomplish this for a client and I feel like I've hit a roadblock

If you can describe here, with the video, it will be better.

Not everyone is patient enough to watch videos (for example me) ✌️

Have a page for each type of item...kitchens, bathroom, furniture, etc...needs to be this way for SEO purposes as she explains in the video

On the individual item  page (Refrigerator from a kitchen page , sofa from the furniture page, etc..)  the client wants to populate the category field with the property address.

Client wants to use the category info (The property address) to populate a summary block at the bottom of the individual page with items from other pages that match the same category.

Problem is...categories and tags are specific to each page and are not available this way.  I cant seem to set a summary block to pull category items off an item page thats not the same item page i'm on.

I hope that makes sense.

I loved the video but I see Tuanphan’s point. I guess we all have different preferences. 😀

As you’ve found, the Summary Block is super effective but can only connect to one collection (one blog in this case) at a time. The obvious workaround is to place all the items in a single blog and then create pages that filter this blog to recreate the individual pages that you currently have. Squarespace improved SEO for this a year ago.  However, you’ve said that you cannot do this, so I mention it for the benefit of others. 

The other way to achieve this is to leave the content where it is and then copy each collection into one super-collection. The first step is to retrieve the content from each blog collection using JSON. Next, the collections need to be synchronised and combined into one large collection. Once the data has been aggregated, the Summary Block can connect to this new collection and be filtered as required. This is complex and shouldn't be underestimated. If done incorrectly, page performance will suffer. Michael has built an excellent extension/plugin that takes care of all the difficult steps. I’d recommend checking whether this will help in your circumstances.

Hoping you and yours are safe and healthy.

Paul..I see why you're a circle leader.  Excellent response and feedback.  It's much appreciated.

Looking into the plugin and will study to see if this will be effective.  

Stay safe and health

Thanks again.
