I would like each page in my link directory to have a page title and meta tags that are relevant to the category of links on that particular page. How can I do this with LinkMachine?

Besides #CONTENT#, there are several other key words that you can include anywhere in your link page template file, and LinkMachine will replace them with the appropriate text for the page being generated. #CTG_NAME# will be replaced with the name of the page's category, and #CTG_DESC# will be replaced with the category's description. You can use these key words in the title or meta tags of your page template to insert information about each link page's category there.

Another option is to create a custom page template for each individual category page in your link directory. After creating a custom page template for each category and uploading all of them to LinkMachine (as described here), you can select which template to use for each category, under Change Settings >> Link Categories. On this page select the name of a category, then choose which template to use for that category from the pop-down menu labeled Category Link Page Template, and click Update Template. Do this for each category that you'd like to have a customized page. The initial setup time this takes is worth it - this method allows you to place category-relevant keyword phrases in each page's title and meta tags, and even to include articles, ads, affiliate links, etc., that are specific to each individual page's category.
