Magento 2 – Product Import Successful but Not Showing on Frontend

At Magento, after every products upload, you need do a reindex .

At Magento 2, to run the reindex, you should setup cron job.

If you want reindex immediate then you should run php bin/magento indexer:reindex command from Terminal.

I think you have not generated the Static View Files. The static view files refer to the files which are not generated dynamically. These files include images, CSS and JS files. These files are located in the pub/static directory of your Magento 2, and some are cached to the var/view_preprocessed directory as well.

The static view files must be written to the Magento 2 file system using the Command-Line Interface (CLI). To do so, first of all delete caches, sessions & old files that are generated before. To delete caches and sessions, navigate to the following paths and delete everything:

MAGENTO2_ROOT > var > cache > *DELETE ALL*
MAGENTO2_ROOT > var > page_cache > *DELETE ALL*
MAGENTO2_ROOT > var > session > *DELETE ALL*
MAGENTO2_ROOT > var > view_preprocessed > *DELETE ALL*

Also, remove everything including old generated static files from below path except .htaccess file:

MAGENTO2_ROOT > pub > static > DELETE ALL EXCEPT .HTACCESS

Now finally to deploy static view files and re-index the indexers. Run the following CLI commands in Magento 2 root directory:

php bin/magento setup:static-content:deploy

php bin/magento indexer:reindex
