SEO modules, which one shoul i buy?

[GusKa76]

Hi, I have prestashop 1.6.1.6 and need advice on what modules to buy improve the SEO. Because there are different, I would not want to find myself serving the same thing.

Which one should not I buy? Or would I have to buy all of them?

Do you recommend others?
