Those who use WordPress may be familiar with Ping-O-Matic for keeping blog search engines updated whenever a new post is written.
I discovered that Bing had more of my posts indexed than any other search engine. I could manually submit the link for each post to Ping-O-Matic, but that would be no fun. Instead, I decided to automate the process.
The Bing Search API is free for use up to 5000 queries per month. All you need is a Microsoft account to get a key from the Microsoft Azure Marketplace.
Once you have the key, you can set up two files: the first is called bing_basic.html, and the second is bing_basic.php. These files are a mashup from the Bing Search API guide and a function created for sending pings to Ping-O-Matic.
bing_basic.html:
<html>
<head>
<title>Bing Search Tester (Basic)</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<h1>Bing Search Tester (Basic)</h1>
<form method="POST" action="bing_basic.php">
<label for="service_op">Service Operation</label>
<input name="service_op" type="radio" value="Web" CHECKED /> Web <input name="service_op" type="radio" value="Image" /> Image
<label for="query">Query</label>
<input name="query" type="text" size="60" maxlength="60" value="" />
<input name="bt_search" type="submit" value="Search" />
</form>
<h2>Results</h2> {RESULTS}
</body>
</html>
bing_basic.php:

Put both files into the same folder on your website. When you open bing_basic.php in your browser, it should look something like this:
In my case, I wanted to get all the pages that Bing had indexed. I entered “site:deepinthecode.com” into the Query box and clicked Search.
After a moment, the page refreshed with the following results:
The “ok” status shows that the ping was received properly and the line below shows the status message. Following those lines are the hyperlinked post titles and the beginning of each post.
Had the ping not been received, the status would be “ko”, and the message would (hopefully) be descriptive of why the ping did not take.
The function in the PHP file can be modified for use with APIs other than the one for Ping-O-Matic, though I haven’t had time to make any changes there yet to see how well it will work with other sites.
