Is there any way to check if the cron job is running correctly?
If there are some pages analyzed, it's working.
On my site there would never be finished the site analysis
Analysis is never finished. That's the major feature in 4SEO. It constantly monitors your pages and when it thinks a page may have changed, it puts it back up onto the list for later, offline analysis (triggered by frontend visits).
That's how new pages are added to sitemap, or removed from it if you noindex them for instance.
If there was no page waiting analysis, then yes, the "cron" system would likely not work.
If I would manually start to do this
Triggering an analysis from the admin is only a way to:
- get started or check things out quickly during development
- when the site does not have any frontend visit (again, when developing usually)
After the initial setup, there's no need to run analysis from the admin.
One word of caution though: on many sites, there are pages that are totally useless to analyze. You should exclude them from the analysis process (see documentation on that here), if that's the case on your site.
