Hi
If there's still room for using 4SEO on the original site for redirects (there are 4-5 URL's for each page due to multiple menus/categories) might it be worth ensuring those are done first, then I can be sure to redirect the new site's URL'S in the same manner, if possible.
That's usually something taken care of with canonical tags, not redirects. And if this is regular Joomla articles, then 4SEO should be able to automatically add canonical tags on duplicates.
If a user is in category A, and they click on a link to a tour, they kind of expect to "stay in the same category", not be redirected to another category. That's why usually no redirect happens, but instead a canonical tag in injected in the "duplicate" article, pointing at what's considered the "main address" of that article.
For example let's say currently can become pretty complex with https://site.com/style/location/booking type/category /tour name/tour#, bloody long-winded IMHO
Which is totally fine.
Our previous site was simply https://site.com/tour name
Which is a bit of an issue long term, because without categories, it's hard to apply things like redirects, canonical, noindex or other SEO-related tags.
The only way to redirect /tour to something else is to painstakingly add one redirec for it. If you want to noindex, redirects, etc 100 of such pages, you'll have to add 100 redirects, one by one.
If you have 100 products in the /europe/tours (with URLs such as /europe/tours/first-tour) and you want to express that the main URL is in the /tours/category (ie /tours/first-tour), then you can add a single canonical rule that says:
to all pages in the /europe/tours category, add a canonical to the same URL but in the /tours category.
I've not managed to find a single tour with less than three steps away from the site's basic URL,
Which 100% fine. And like I said, likely preferred in terms of management. URLs with 2 or 3 categories segment are fine, and they won't hurt your SEO results at all. URLs are just identifiers.
You are confusing 2 entirely different things:
1 - The URL structure (/europe/tours/first-tour vs /tours/first-tour): no problem, even recommended
2 - The "click-depth": that matters but is not related to URL.
Click-depth is how many click I need to get to your page from home page. Nothing to do with the URL. This is about your menu structure, and whether you directly link sub-categories from the home page menus, or from a second page.
Google does not care at all if your URLs are like /cat/sub-cat/sub-sub-cat/tour (well, don't have URLs with 1000 caracters!). What's important for them is whether a user needs to click through 20 times from home to get there.
Their theory is: things that are easily reached are likely more important. Things that are 20 clicks away, the website owner consider them less important, so we're also going to consider them less important (and maybe down-rank them, or even just not crawl/index them at all).
It's the clicks that matters, not how many segments you have in your URLs.
