Everybody has an experience with websites being unreachable because of web hosting or technical problems. After that, we may forget to check that website again or spend so much time to see whether it is online or not.

Mr Uptime simply informs the user when an unreachable website becomes reachable again.

Usage is also simple. When a website in unreachable at the time you’re trying to browse, a small menu appears which helps you to add the website to the watchlist with 1 click. Another nice feature is watching a website for a text parameter to appear too. If that text appears on the website Mr Uptime warns you.

They create a new banner area for websites without effecting the current banner areas and easy to implement. On the other hand, pagepeel banners have a relatively high "click per view ratio".

Including Pageear to the websites requires the steps below:

- Download Pageear files.
- Unzip the filed in a folder.
- Create to images with sizes 100×100 and 500×500. 100×100 sized image is the one which will be shown when Pageear is closed and 500×500 will be shown when user mouse overs the Pageear banner. You can pageear_b.jpg ve pageear_s.jpg files as an example. BTW, .GIF and .PNG are not supported.
- Open the Pageear.js file wit a text editor and update the paths to the .JPG and .SWF files depending on your setup.
- Include Pageear.js and AC_OETags.js in to the webpages where Pageear banner will be displayed (example below).
- Place the writeObjects() javascript function under your body tag.
- That’s all.

Pageear can also be implemented easily with the ready to use Wordpress plugin, Joomla module or Typo3 extension (download links below).

<html>
<head>
<title></title>
