how much landing page copy affects QS ?

keywords on headings, bold text, links, page title

On-Page SEO must have keywords on landing page copy. I would like to know how much Adwords requires it, and if i put keywords on headings, bold text, links and page title how it will affect QS.

SPECIALLY When:

1. each ad created for different theme such as Affordability, Production Time, Business type/industry.
2. landing page is made for each theme. thus highlighting that theme's features and showcasing items related to that theme.

If you get the "Landing Page: No Problems" in green and "Landing Page Load Time: No Problems" in green then you cannot improve your QS any more by improving your landing page (despite what keeps getting passed around among PPC expert circles).

Agree with Baylow.

QS is about 65% CTR. Obviously, changing the landing page will not affect this rather large portion.

About another 25% is keyword relevancy. This is either on or off. There can't be in-between relevancy just like you can't be "a little pregnant". You either are or you're not.

Keyword relevancy is about what your page is all about. Yet, many advertisers still see it as a chicken and egg thing. They want to bid on highly searched keywords like "paris hilton" when their site is about dog obedience training. So they change the site to try to make it more relevant to the paris hilton keyword. Your site is about one subject, bid on keywords related to the subject, nothing else.

The rest, about 10% is other factors. One that Google has said is page loading time. It may be the whole 10% or just half of it, other factors being stuff like privacy policy.

Adwords is not SEO and having keywords in headings, bolded or a certain percentage of the copy will affect QS very little, if at all. Google takes more of an overall view of the page and determines a theme. It then determines if your keywords match the same theme. The rest is up to you and get your click rate as high as possible with your ads.
