Backlink Checker | |
| Check how many external URLs are linking to your site (verified by Yahoo Search API). |
|
HTML Page Size Test | |
| Check your page’s HTML size. HTML size is the size of all the HTML code on your web page – this size does not include image, external javascripts or external CSS files. |
|
|
Favicon Test and Validator | |
| Check if your site is using and correctly implementing a favicon. Favicons are small icons that appear in your browser’s URL navigation bar. They are also saved next to your URL’s title when bookmarking that page. They can help brand your site and make it easy for users to navigate to your site among a list of bookmarks. |
|
Page Cache Test | |
| Check if your site is serving cached pages. Caches reduce server-load (since pages are generated less often) and speeds up page display (by caching page ouput vs compiling the php-page). Caches also reduces bandwidth requirements by up to 80%. Caching makes most sense for high traffic pages whose content does not change on every page view. Common caching methods are Quickcache and jpcache. |

|
URL Canonicalization Test | |
| Test your site for potential URL canonicalization issues. Canonicalization describes how a site can use slightly different URLs for the same page – for example: if http://www.example.com and http://example.com displays to the same page but do not resolve to the same URL. If this happens, search engines may be unsure as to which URL is the correct one to index. Learn more about canonicalization issues. |
|
Libwww-perl Access Test | |
| Check if your server allows access from User-agent Libwww-perl. Botnet scripts that automatically look for vulnerabilities in your software are sometimes identified as User-Agent libwww-perl. By blocking access from libwww-perl you can eliminate many simpler attacks. |
|
Site Loading Speed Test | |
| Check the average load time of your site, and how it compares to the load times of other sites (based on users’ average load time verified by Amazon Alexa API). |
|
Server Signature Test | |
| Check if your server signature is on. Turning off your server signature is generally a good idea from a security standpoint. |
|
Directory Browsing Test | |
| Check if your server allows directory browsing. If directory browsing is disabled, visitors will not be able to browse your directory by accessing the directory directly (if there is no index.html file). This will protect your files from being exposed to the public. Apache web server allows directory browsing by default. Disabling directory browsing is generally a good idea from a security standpoint. |
|
Visitor Breakdown Test | |
| Check where the visitors of your site are coming from (based on users of Amazon’s Alexa toolbar – verified by Amazon Alexa API). |
|
Image Expires Tag Test | |
| Checks if your page is using an image expires tag, which specifies a future expiration date for your images. Browsers will see this tag and caches the image in the user’s browser until the specified date (so that it does not keep re-fetching the unchanged image from your server). This speeds up your site the next time that user visits your site and requires the same image. |
|
|
|
Nested Tables Test | |
| Check if your site is using nested tables, which can slow down page rendering in the user’s browser. |
|
|
IP Canonicalization Test | |
| Test your site for potential IP canonicalization issues. Canonicalization describes how a site can use slightly different URLs for the same page for example: if your site’s IP address and domain name display the same page but do not resolve to the same URL. If this happens, search engines may be unsure as to which URL is the correct one to index. Learn more about canonicalization issues. |
