Each Tuesday I publish the popular "Things to Do in Houston, with Kids, this Week and Weekend" post.
If your event was listed, it would be included in a post like THIS one. (You post will go live the Tuesday before your event.) Being listed is $15.
If you want to be included in the introduction of that Tuesday Post, the cost is $200. For this $200, you also get mentioned in posts on Monday, Wednesday and Thursday.
So the $200 option for your Houston Events, also includes this coverage:
1. Monday, Top Things to Do this Week
2. Tuesday, Events Listing + Mention in Introduction
3. Wednesday, Video of Favorites
4. Thursday, Audio Clip of Favorites
All of these event posts stay on the front page of the blog (center, left column) all week. They are also listed very high in Google searches for "Things to Do in Houston with Kids" and similar searches.
If you want a dedicated sponsored post, it could look something like THIS. The cost is $450 for this, and I can include the event listings & highlight (a $200 value) for no additional charge.
