SEO Tips:
1 This page size is 215.32KB. The average web page takes up 320KB on the world wide web. Googlebot will crawl the first 100KB of html on a page. The page size should ideally be less than 100KB. We recommend that you should minify your HTML. Minifying THML refers to eliminating unnecessary bytes, such as extra spaces, line breaks, and indentation. For minifying HTML, PageSpeed Insights Chrome Extension can help you generate an optimized version of your HTML code.
2 The homepage load time is 1.897 seconds (113.5 kb/s). It is too slow. Fast and optimized pages lead to higher visitor engagement, retention, and conversions. How to speed up your website? I think this tool PageSpeed will be helpful to you.
3 You do not specify a canonical URL on your site. It's common for a site to have several pages showing the same contents. If search engines know that these pages have the same content, we may index only one version for our search results. How do I specify a canonical URL?
4 This site has more than 12 Script HTTP request(s). The page could eliminate more than 11 HTTP request(s) if you combined all scripts on the same host into one.

6 We did not find CSS-based print-friendly versions on your site. You can use the very same HTML but applying a different stylesheet, in which you can disable menus and other elements that make no sense on paper. Just use the media="print" attribute in your head link.
