Install the Cognatu Ads WordPress plugin, then go to Settings → Cognatu Ads and enter:

            
          

          
Then add [cognatu_ad] anywhere in a post or page.

        


        
        

          

            

            
          

          
Paste the <script> tag once in <head> or before </body>, then add slot divs wherever you want ads.

        


        
        

          

            

            
          

        


        
        

          

            

            
          

        

      


    

  


  
  

    

      
Why Cognatu?

No cookies, no tracking

          
Ads are matched to page content. Not visitor history. Zero third-party cookies required.

        

      


      

        
⚡

        

          
In parallel, or not at all

          
The auction never sits on your response path, and every SDK applies a hard deadline. If no ad is ready in time, the slot stays empty and your page is unaffected.
