The web is big. Really big. You just won't believe how vastly hugely mind-bogglingly big it is. I mean, you might think it's a lot of work maintaining your website, but that's just peanuts to the whole web. (with profound apologies to Douglas Adams)Search engines like Google read through all this information and create an index of it. The index allows a search engine to take a query from users and show all the pages on the web that match it.
The User-Agent line specifies that the next section is a set of instructions just for the Googlebot. All the major search engines read and obey the instructions you put in robots.txt, and you can specify different rules for different search engines if you want to. The Disallow line tells Googlebot not to access files in the logs sub-directory of your site. The contents of the pages you put into the logs directory will not show up in Google search results.User-Agent: Googlebot
Disallow: /logs/
This stops Google from indexing this file. META tags are particularly useful if you have permission to edit the individual files but not the site-wide robots.txt. They also allow you to specify complex access-control policies on a page-by-page basis.<html>

We're excited to announce that AdWords Editor is now available for Mac users. Just like the Windows version, AdWords Editor for Mac allows you to navigate your AdWords account quickly and easily as well as make bulk changes to keywords and ad text. Mac users running OS X (10.4 or later) can download the application from the AdWords Editor website. For a full list of features, check out the release notes section of the website.
And if you're wondering how you might use a group, how about:
We hope you enjoy Google Groups; we really enjoy working on it, and it's been very rewarding to see all the useful things you and so many others have done with it.
1. Test - Even a finely tuned account can typically be improved. You may have keywords that are no longer driving quality traffic, ad text that is getting stale, or landing pages on your website that aren't converting. Google AdWords lets you experiment with everything from new keywords to different ad text to different landing pages. If you're not testing, you may be missing out on opportunities to increase your return on investment.
2. Evaluate - As important as testing is, it's also important to measure the impact of your experiments on performance. Trust the results you see and make changes that can help you achieve your goals, whether they are to increase traffic or conversions. Online advertising is trackable and your AdWords account provides a lot of insightful performance information.
3. Iterate - AdWords has many more features than it did five years ago. To achieve the best results on your campaigns, you'll want to do more than just create an account and forget about it. Running a successful account requires time and attention. Once you have evaluated your tests, you may find that it's time to start over and do it again.
We will be performing AdWords maintenance from 8 a.m. to 8 p.m. PST tomorrow – Tuesday, January 9, 2007. While all AdWords advertisements will continue to run as normal and you will be able to log into your account, you may not be able to run or retrieve reports, or upload image or video ads during this time.Posted by Judy, Inside AdWords crew
