Dynamic titles are easy, they don't cost anything and they usually have a good effect on CTR and conversion rates. The phrase that the searcher uses in their search will come up as the the title of your AdWord. This saves you having to create an individual ad for each keyword and means that your ad will be more targeted. In the title field of your ad simply put {keyword:your backup title here}. The backup title is in case the search phrase is too long for the title field or if AdWords can't display the search for some other reason.
Dynamic titles are very effective, improves the clickthrough and conversion rateswhen implmeneted. As standard practice I always use the dynamic keyword insertiontool on all my clients accounts.
Do a google search for DKI Adwords (DKI=Dynamic Keyword Insertion) -- very easy to implement, but ensure that any keywords you have under that ad group will make sense when auto-added to your ads.
yes, DKI helps to build the most relevant web pages, perfectly targeted for specific user groups and keywords themes, with some effort and also it is an advanced adwords feature.
DKI is very useful, 'cause it allows people to see what they need to see. With the help of DKI you can add group of words, if your website concerns different type of books, you are added with books, historical books, fantasy book, fiction book, etc. so, when one looks just for books, he/she will find just books. When one searches for historical books, he/she'll see historical books, etc!
It's very good to get your Click Through Rate up there and can attract the eyes of the surfer, so you should use it when you can definitely.
