Your website does not have an XML sitemap - to make it easier for search engines to find your pages it is wise to generate a sitemap.

A sitemap lists URLs that are available for crawling and can include additional information like your site's latest updates, frequency of changes and importance of the URLs. This allows search engines to crawl the site more efficiently.

Go here to know more on how to set this up: http://www.sitemaps.org/protocol.html

If you have a lot of pages (up to 500 pages is free) you can auto generate them here: https://www.xml-sitemaps.com

Enable compression for the following resources to reduce their transfer size by 128.9KiB (67% reduction).

  • Compressing http://code4app.com/source/plugin/zb7com_kefu/template/default/js/jquery.js could save 58.8KiB (64% reduction).
  • Compressing http://code4app.com/static/js/common.js?j0C could save 44.5KiB (71% reduction).
  • Compressing http://code4app.com/static/js/forum.js?j0C could save 15.6KiB (70% reduction).
  • Compressing http://s11.cnzz.com/stat.php?id=1258435564 could save 6.4KiB (65% reduction).
  • Compressing http://code4app.com/static/js/redef.js?j0C could save 1.9KiB (64% reduction).

Leverage browser caching
Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.

Leverage browser caching for the following cacheable resources:

  Consider Fixing:
Minify JavaScript
Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and execution time.

Minify JavaScript for the following resources to reduce their size by 17.6KiB (21% reduction).

  • Minifying http://code4app.com/static/js/common.js?j0C could save 11.8KiB (20% reduction).
  • Minifying http://code4app.com/static/js/forum.js?j0C could save 4.7KiB (22% reduction).
  • Minifying http://code4app.com/static/js/redef.js?j0C could save 1KiB (36% reduction).
Show how to fix
Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 2 blocking script resources and 2 blocking CSS resources. This causes a delay in rendering your page.

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

Remove render-blocking JavaScript:

  • http://code4app.com/static/js/common.js?j0C
  • http://code4app.com/static/js/forum.js?j0C

Optimize CSS Delivery of the following:

  • http://code4app.com/data/cache/style_1_common.css?j0C
  • http://code4app.com/data/cache/style_1_forum_forumdisplay.css?j0C
Show how to fix
Optimize images
Properly formatting and compressing images can save many bytes of data.

Optimize the following images to reduce their size by 54KiB (61% reduction).

  • Compressing and resizing http://code4app.com/data/attachment/forum/201604/07/120503mqbq8ktyh8188wcu.png could save 42.2KiB (62% reduction).
  • Losslessly compressing http://www.code4app.com/static/image/common/pt_item.png could save 3.4KiB (96% reduction).
