About search engines
Well first of all does your site have a lot of content? You should have anywhere from 300-600 words on your site to be search engine friendly. It is ok to go over 600 but you should have atleast 300 words(not pictures with words on them) And also you should disregard the meta tags for title and subject the search engine spiders pay no attention to them. Your meta description is what you should put the work into have that towards the top with keywords right under it. The keywords are not very important but some search engine spiders still use them. Your description should be between 25-30 words but try not to go over that and try to research some of the most searched for keywords in the fields that yyour sites are gonna be in and try to incorporate them directly into your description. Let me know how that all works out for you
