Upgrade your site checklist
You already have a site - now you want to upgrade it, what should you do ? Make it fast - preferably not having any server side code (no php etc) just plain html Use Xenu to see that there are no broken links Redirect your site to the www domain Create a 404 page (or redirect to your homepage) Make it responsive ! Reduce the size of the site components Compress images (many online services) Dust off unused CSS selectors Minify CSS Minify JS Minify Html Instead of minifying the above resources (css, js, html) use Google's minifier which minifies all of the above on the fly (also uses cache) and even joins the CSS & JS together so you will have less server calls. Use GTMetrix to analyze then implement their suggestions Use Google Page Speed to analyze then implement their suggestions Don't stop implementing speed fixes according to the above analyses till you get above 90% speed score!
