เพื่อความชัวร์ ผมเลยเข้าไปค้นดูจาก หน้าของ กูเกิลแอดเซนส์ ลองอ่านดูนะครับ
https://support.google.com/ads...swer/1346295#Ad_limit_per_page รายละเอียดตามนี้ครับ เผื่อบางท่านขี้เกียจกดไปดู คร่าวๆ ตามนี้ครับ
( ผมก็ต้องจดจำแบบนี้แล้วครับ)
Ad limit per page
Currently, on each page AdSense publishers may place:
Up to three AdSense for content units
Up to three link units
Up to two search boxes
Publishers may not place more than one "large" ad unit per page. We define a "large" ad unit as any unit similar in size to our 300x600 format. For example, this would include our 300x1050 and 970x250 formats, our 750x200 and 580x400 regional formats, and any other custom sized ad with comparable dimensions.
However, keep in mind that placing the maximum number of allowed ad units on a page might result in it looking cluttered. Read our optimization guidelines for tips on where to place your ads. For best practices on custom sized ad units, review our custom-sized ad units page.
The above ad limits also apply to mobile sites. In addition, two or more AdSense ads may not appear on the screen at the same time on a mobile site.
