searchers focus on:
- Title: 30 %
- Snippet: 43 % *
- URL: 21 %
- Other: 5 % (cached, similar pages)
It's propably easy to change (with CMS) your landing pages' titles and body text, right? And the system creates nice, short and understandabe URLs which you don't have to worry about. Now you just have think about your search result as your short online ad. For example, if you're selling christmas trees either online or off-line, your title might be something like this: "Christmas trees - check out our special christmas tree offer". Google will show 65 characters from the title, so you have to remember that. And the start of your body text could be something like this: "Order your christmas tree well before holidays and get our special christmas tree offer. Order online and get a free christmas tree delivery or print your coupon to receive special chistmas tree offer in our store.
I hope you got the idea. With Adwords you can't use so many characters, so it's little easier to think copy text for search engines. And in my opinion, you should use same campaign idea and message both online (banners, newsletters, paid and organic search) and off-line marketing activities (radio, newspaper etc.). But somehow you should be able to measure those off-line marketing tricks, so you could evaluate your the whole marketing mix and what is the most profitable channel for your business.
* Snippet = the short paragraph that a search engine generates from page's body text or page discription (meta data) under the title to display the relevant information on the page for the query.
