Hi
since it does so many things on autopilot if it also has the abiltiy for manual customization.
100% of what it does can be customized manually, from the user interface. Which is why we built a modern, single-page-application user interface to provide a more confortable environment and do away with page reloads and slow reaction times.
It's even more customizable than sh404SEF or any other SEO extension because we have built-in "hooks": with a little bit of PHP code, you can customize most of the internal 4SEO data and output, in an extremely simple way. See 4SEO programming API here.
Again, you don't have to use programming to customize, everything can be done from the UI.
can you change those structured data items page by page as well ... for example on a specific page override the rules and mark things manually?
Yes, you just enter the desired URL to which the custom structured data applies to:
Most things in 4SEO are rule-based. The rules you define can apply to a single page or a group of pages or all pages - as defined by URL or component or categories:
It's very flexible and indeed you can just enter a single URL. Note that for meta data, canonical, sitemap inclusion, open graph image and a few other things, it's even simpler as we do have a list of pages:
Do you have the ability (I assume you do) to set which page is canonical or is it just done on auto?
Is there a way to manually adjust what is in the sitemap or is it always auto generated?
You can do it both ways:
- with a rule if you want to affect multiple pages with one rule
- or on the main Pages page:
Whether for canonical or sitemap inclusion, you leave it on Auto or force Yes or No per page.
It looks like it provides all the things sh404 provided and more but are there any features provided by sh404 that are not included in 4seo?
Yes, the big one: 4SEO does not deal with SEF URLs at all. It's designed to operate without even knowing how SEF URLs are generated, meaning it can work with just Joomla standard SEF URLs, with sh404SEF or with JoomSEF, MijoSEF or anything else under the sun.
Make sure to look at my recent blog post on what happens to sh404SEF, 4SEO and all our extensions in the near future with Joomla 4 becoming a reality.
