I got this from google this morning in reference to having my keywords in the ad title.
KEYWORD IN TITLE
You can use our keyword insertion tool to show a search term from your
keyword list in your ad text automatically. This tool minimizes the manual
edits required to create unique ad text for accounts with large amounts of
keywords.
Please use keyword insertion with the requirements detailed below. If your
ad(s) and/or keyword(s) are not in compliance with all requirements, they
will be disapproved by AdWords Specialists.
I. Keyword Insertion Format
To use keyword insertion, include {KeyWord

efault Ad Text} in your ad
text where you would like the keyword a user searches on to appear. The
keyword inserted in your ad is capitalized depending on how you format the
word 'keyword' in the curly brackets.
In this example, the keyword 'fast red car' could appear in an ad in the
following ways:
{keyword

efault Ad Text} = fast red car
{Keyword

efault Ad Text} = Fast red car
{KeyWord

efault Ad Text} = Fast Red Car
II. Other Requirements
- Default Ad Text: You must include default ad text in case your keyword
exceeds ad text character limits. If you do not include default ad text,
your ads and/or keywords will be disapproved.
- Character Limits: The headline can include up to 25 characters, and the
following two description lines can include 35 characters each, including
spaces.
- Non-Latin Characters: If you create text ads using non-Latin characters,
please be aware that the character limit may vary. Ads in languages with
double-byte characters, such as Arabic, Chinese, Japanese and Korean, can
contain the following number of characters, including spaces: 12
characters in the title, 17 characters in each line of ad text, and 35
characters in the display URL.
- Editorial Guidelines: Ad text using keyword insertion is still subject
to our Editorial Guidelines, which can be found at
https://adwords.google.com/select/guidelines.html. Therefore, if your ad
text and/or inserted keywords are not in compliance, your ads and/or
keywords will be disapproved.
III. Example
1. Original ad text:
Visit {KeyWord: the Amazon}
Gorgeous Vacations For The
Entire Family; Try Us Out!
TheAmazonJungle.com
Notice in the title, 'KeyWord' is shown with initial capitalization.
2. Ad text seen on a search for 'amazon jungle':
Visit Amazon Jungle
Gorgeous Vacations For The
Entire Family; Try Us Out!
TheAmazonJungle.com
Notice in the title, the keyword 'Amazon Jungle' is shown with initial
capitalization.
3. Ad text seen on a search for 'amazon rain forest':
Visit the Amazon
Gorgeous Vacations For The
Entire Family; Try Us Out!
TheAmazonJungle.com
Notice the default ad text shown in the title, because the keyword 'amazon
rain forest' is too long.
