is there any flaws in joomla? many of my joomla sites are poorly ranked and loads slow..any idea guys?
Without any SEF Component it is not easy to be ranked as Joomla's actual urls are quite non friendly. I would recommend JoomSEF
you will need some components for seo, sef and to speed you joomla ,i recommend you to use: Ircmaxell's Page Cache;open sef and SEF patch extended version,,,those components will rank better your joomla websites. P.S-if you need help you can PM me. Good Luck!
