I bought a website, http://www.bigdealsonweb.com, and it has Allinoone and Platinum on it for SEO titles, description, H1 etc. I added Yoast, as I prefer Yoast. My question is, with 3 or even 2 SEO plugins, what happens to the titles and other meta, and which plugin takes precedence? I could delete the other plugins, but I dont want to manually go and fix the meta for the 72 posts made before I bought the site. Sorry for the newbie question!
