Auction Meta Tags


of 5 


The purpose of meta tags is to allow web utilities to extract pertinent information from html web pages. The data is embeded into the header portion with a name and content construct. All meta tags are contained within the header tags.

<head> ... </head>


Auction uses meta tags to harvest event data from various auctioneer and auction house websites. Much of the information is contained in the basic meta tags like title, description, subject, and keywords. Some of the tags are used in a specific method that is a slight variation from internet standards while others are entirely custom for the auction industry. In all cases the names are in simple english and self explanatory.

Other Considerations

Meta tag field names are not case sensitive and can contain hyphens or underscores to improve readability.

PHP code:

 preg_replace('/[^a-z]/', '', strtolower($string))
