Sitemap
To configure the site map, go to "Modules -> All modules -> Sitemap".
The site map is available when opening the site for robots in the section "Settings -> Global settings -> Open the site for indexing robots". Without the active flag, the sitemap will be empty.
The sitemap responds to the link http(-s)://site/sitemap.xml
In the settings, you can set the ability to generate a map each time the search bot visits or give it an already saved one (description will be below).
If the sitemap has more than 10k pages to generate, the map will be divided into several files.
Priorities
In the priority settings, you can set the priority of the URL relative to other URLs on the site. The priority assigned to the page does not affect the position of your URLs on the results pages of a particular search engine. Search engines use this information when processing URLs that refer to the same site, so you can use this tool to increase the likelihood that your most important pages will be included in the search index.
Change Frequency
The approximate time period after which a page may change its content. The value "always" should be used to describe documents that change every time these documents are accessed. The value "never" should be used to describe archived URLs. The rest is up to you, depending on the page refresh.
URL Blocking
The tool allows you to specify a small number of links that will not be included in the sitemap. Perhaps these may be technical links or closed content that is not available on the site, but is implemented in such a way that it is included in the site map.
Settings
Here you can configure the sitemap submission to the search bot. You can save the sitemap once and give it the finished saved files via the link /sitemap.xml or generate a fresh map each time the bot enters this link.
If the site has more than 30 thousand products, then depending on the server, the "on the fly" function may not have time to complete. To do this, you can configure the formation via the scheduler Cron. You should select the option "Give robots the saved version of the map" and set the task on cron.
Link to set the task in the scheduler:
php full path to the project/index.php sitemap make_cron_sitemap
Make sure that in /your project/application/config/config.php in $config['base_url'] = ''; (item 4) the domain of your site is specified correctly.
