It would be nice if you could import 301 URLs in bulk but I could not find a way via the JoomSEF admin area.
I had tons of 301 redirects I needed to specify and entering them 1 by 1 via JoomSEF was too time consuming so I wanted to share how I accomplished this using a MySQL command.
I logged into PhpMyAdmin to access my Joomla database, clicked SQL and entered the following command:
INSERT INTO `jos_sefmoved` (old, new, lastHit) VALUES ('blog/designing-a-website', 'web-design/designing-a-website', '0000-00-00 00:00:00');
INSERT INTO `jos_sefmoved` (old, new, lastHit) VALUES ('general/designing-a-website', 'web-design/designing-a-website', '0000-00-00 00:00:00');
INSERT INTO `jos_sefmoved` (old, new, lastHit) VALUES ('blog/spam-traffic-increases', 'general/spam-traffic-increases', '0000-00-00 00:00:00');
I then clicked Go and above 3 entries were added as Rows within the table.
