A single adsense unit is returning all of the following optimization messages...
- There are 4 JavaScript files served from pagead2.googlesyndication.com. They should be combined into as few files as possible.
- The following 5 publicly cacheable resources should have a "Vary: Accept-Encoding" header: googleads.g.doubleclick.net/pagead/test_domain.js, pagead2.googlesyndication.com/pagead/expansion_embed.js, pagead2.googlesyndication.com/pagead/render_ads.js, pagead2.googlesyndication.com/pagead/show_ads.js, pagead2.googlesyndication.com/pagead/sma8.js
- The following cacheable resources have a short freshness lifetime. *same files as above*
- Put CSS in the document head, ttp://googleads.g.doubleclick.net/pagead/ads... has CSS in the document body: 3 style block(s) in the body should be moved to the document head.
Now I realize there are other considerations but can anything be done to improve any of the above? The inline css especially? A single adsense unit involves an awful lot of objects already.
