SEO and meta tags setings

Hi!
Can You help me, please? I do not know how I can seting SEO for my website… I used a SEO + setings website by meta tags too, after, when it not working, I inserted meta directly into the pages, but SEO analyzer and browsers still can not find title, author, discription, keywords… nothing!

Please see this topic: https://forum.infinityfree.com/discussion/2263/seo-bots-are-not-reading-my-code-properly-on-infinityfree-hosting-why/p1

Thanks
