So here’s a quick tutorial on how to insert Adsense advertisements into WordPress (in your posts). Simply go to Plugins, Add New to get started and find “WP-Insert”.
After that, go to the top right of the WP-Insert dashboard, you’ll see an “In Post Ads” feature, click on “Add New”.
Now you will be taken to the settings of the “In Post Ads” which you will see the option to show your advertisements at either “Above Post Content”, “Middle of Post Content”, “Below Post Content”, “To the Left of Post Content”, and last but not least “To the Right of Post Content”. Click on “Above Post Content”.
Also make sure to click the Red button at the bottom left of that window to enable the advertisements.
Paste your code into the top left space of the plugin settings where it says “Generic / Custom Ad Code”. After that hit “Update” and then go to a post on your blog and see if the ads show up.
As you can see the adsense code worked for me perfectly!. Hope that helped you. Oh and you might already see the advertisements in this post too, obviously.
