To create titles click on WAC Xtra tab and then on Title Builder. Title Builder creates titles from two sources - one local database and one WAC database.
1) Local database - This is a local database of over 30,000 titles which are very generic and can be used with any keyword. You can choose these for lower tiers for a quick blast.
2) WAC database - This is our article database. While local database will guaranteed build titles for any keyword, this one might fail for narrow keywords.
We do provide an option to use both to create titles. After they are built, click on "Spin Titles Together" to create a spintax from them.
