Seems like a strange tip, Adsense is about SEO? A lot of people focus on tuning their ads to improve the click-through rate but if there is little to no traffic, there will be low earnings. The primary focus to improve your earnings should be to focus on tuning your site so that it shows up high on the search engine rankings. I have a section of the site dedicated to optimizing your site for improving your Google rankings. 

I was able to improve my trafffic more than 10 fold using the tips in that sections and it improved by earnings by about 10 fold as well. 

How many times have you been to a site and seen a Google ad that was completely irrelevant to where you lived or worse, clicked on an ad and found that you are not eligible for the offer or promo because of the place where you live. Quite a few advertisers create Ads and target them to globally or nationally when their real audience is much smaller. 

When creating an Adwords Campaign, you can specify which geographical location the ad should be displayed. The Adwords wizard shown the image below allows you to drill down to Country-> State -> Region -> City as you can see from the image below. The wizard allows me target United States -> California->Los Angeles-Acton. 

If you look at most of the sites, they usually have a left navigation, center content section and a right navigation area.  My site is structured that way and I have experimented with ads on both the left navigation and also the right navigation to see if there was any difference in the click-through rates. Based on a few experiments, I have come to the conclusion that the ads in my left navigation performed a lot better than the ads on the right.  I don't know the reasons why but there was a 2-3 time improvement in the click-through rate. 

Maybe its because English language sites are organized left to right and users may tend to focus their eyes on the left part of the screen rather than the right.

Please read Tip #1 before proceeding.  

Tip #8 is a tip that is sometimes easy to and sometimes not so easy. Having the main keywords in the domain name part of the URL is apparently a big plus, but its not always easy to get that. The next best option is to have the keywords as part of the rest of the URL. As an example, these are some of the pages which get me top rankings in Google

1. Famous Logos - http://www.dinesh.com/History_of_Logos/Worlds_Best_Brands_and_Logos/ which is much better than http://www.dinesh.com/lg/wfmlogo.html
2.  World Famous Logos - http://www.dinesh.com/History_of_Logos/Worlds_Best_Brands_and_Logos/
3.  Ajit Jokes - http://www.dinesh.com/India_Jokes-Humor/Ajit_Jokes/

Tip #6 is a tip that I did not know would influence the rankings. This is something most of us do not do and it has to do with placing ALT tags on images. This really has two benefits

1) Google apparently uses it in some way to determine your page's topic

2) This will also show up in image searches which means more traffic to your website.

Also, if you have more than one image on a page, you can put variations of the keywords on each of the images. I would recommend that you keep this tip in mind when you are creating new pages with images.

Tip #5 has to do with placing the keywords within emphasis tags such as <U>, <I> and<B>. The objective of this is tip is again to highlight the main keywods.

The downside of this tip is not to overdo the uses of these tags. Google will actually delist/ban you from the index if it feels your page is trying to cheat the engine. I personally have not made much use of this particular tip.

Tip #4 has to do with placing the keywords within an <H1> tag and that too as close to the top as possible. The objective of doing this is to highlight the main topic of the page.

<H1>Banjara Palace Restaurant- Tasty Andhra food in Malleshwaram Bangalore. </H1>

The downside of this tip is not to overdo the H1 tag. Google will actually delist/ban you from the index. I personally have only 1 <H1> tag on a given page.

Tip #3 is also a fairly simple tip. Make sure that the keywords you have selected appear in the <META> tag as follows

<META name='description' content='Banjara Palace Restaurant Tasty Andhra food in Malleshwaram Bangalore'>

<META name='keywords' content='Banjara Palace Restaurant Tasty Andhra food in Malleshwaram Bangalore'>

There is some debate about the usefulness of adding the META tags as the Google Search Engine apparently ignores this. However, my thought is that there is no harm in implementing this for two reasons
1) Google may decide to use it in a future version of the algorithm (which is changing all the time).

2) Adding these META tags may tune your pages for some other search engines.

The fact that you are reading this article means that you have some interest in tuning your website in order to get additional traffic to it. As you all know, I insist that anyone claming to get you top rankings in Google is probably cheating you in some way. The tips I am suggesting are ones that I have personally tried and have had very good success with. I wish you luck with the same.

The first and most important thing you will have to do is determine the keywords you are tuning your website for. The trick here is to determine what your potential users are likely to search for. Also remember, do not try and tune for generic keywords because there will be a ton of other sites who have already tuned for it. Lets take an example. Lets say you have an Indian Restaurant called Banjara Palace in Bangalore. The first instinct may be to tune for "Banjara Palace" or "Indian Restaurant". Anyone who already knows your name is not your target audience, although its important to tune for your name as well.  Even if you get in the top list for Indian Restaurant, whats the point, someone in Japan who searches finds you will probably never come to Malleshwaram for lunch.

If you think carefully as to how your customer may be looking for you, you may come up with a different set of answers.

1. What type of cusine is your customer looking for - Andhra, South Indian

2. What words will they be looking for - cuisine, food

3. What location will they be searching for - Malleshwaram, Bangalore

4. What description will they be looking for - cheap, tasty

Based on this information, you may come up with a new set of keywords "Banjara Palace Restaurant - Tasty Andhra food in Malleshwaram Bangalore"

Remember, choosing the right set of keywords is the most important step. Spend a lot of time before you proceed to implementing the other tips.
