I am planning to put a 970×250 large ad format on my site.
It would be located just below the header, above the main content or main body.
How can I put that ad without affecting the CLS?
What do you think is the best method for this?
I tried to put a 160×600 or 300×600 skyscraper ad on the side bar, but it seems to affect CLS.
Right now I haven’t installed any ads yet.
