Thank you so much for your help, althoffm but I solved my problem , with the mega help of Richard ...
and also the fact that I copied the .htaccess example Artio offers when downloaded, which I did not do before and that's one of the reason why it did not work.
So, for the next one you will feel soooo frustated with these SEF, once Artio is downloaded, copy the .htaccess example they give in the instructions, open artio, open "View/edit SEF URLs" and start working (changing the name of links)
Then go to the GREAT Richard's component , SEF patch extended...($11 TOTALLY worth it! and what a support...) and copy and paste the new link you just created with Artio into sef patch , enter you metatags and all, and voila...
A trick from Richard though: I could not have what I call the best of both worlds: Artio was working great, Richard's was working great but for some reason, I was loosing the great additional tags from Sef patch extended when artio was on and Richard's is MUCH better for metatags and everything concerning tags than Artio BUT Richard's cannot change the links name...
Still following me...
Just make sure the Artio bot is UNpublished! That's where I had a problem for a while. And now I just can't stop opening my links and check my tags...a true beauty!
So - site config SEO = ON
change your .htaccess file
Artio bot = OFF
Copy and paste the new links created with artio into SEF patch and start writing your metatags and ADD 5 more if you need with SEF patch.
And hopefully Google will not kick you out because you have a bunch of duplicate with your Sobi2 component...Oh well...nobody's perfect, right? If anyone has the trick to check that., I am listening.
Hope my very little experience and the loss of a lot of hair on Richard's head due to my millions of desesperate emails, will help someone. This guy, for $11 the component, believe me, gives you more support that Adobe for $1800!!!
