Top 5 Sites To Advertise Your Site

Using free tools anyone can achieve a healthy AdSense income, and if they multiply the methods by 100 then they will do very very well with AdSense earnings. Social media sites are the first free tools that I have come to mind, but there is so many of them out there how is anyone supposed to know which one returns the most AdSense earnings.

I think the top 5 are Facebook, MySpace, Reddit, Squidoo, and Twitter.

2 Blog Adsense Tips

1. Ping your blog after each post. You can do this at a site such as http://www.pingomatic.com, which will send the ping to multiple blog directories at one time.

2. You use social bookmarks each time you make a post, tagging the post with your keywords. You can quickly and easily send out multiple bookmarks at one time by using a free service such as http://www.onlywire.com

More Google Adsense Rules

From https://www.google.com/adsense/policies

Invalid Clicks and Impressions

Clicks on Google ads must result from genuine user interest. Any method that artificially generates clicks or impressions on your Google ads is strictly prohibited. These prohibited methods include but are not limited to repeated manual clicks or impressions, using robots, automated click and impression generating tools, third-party services that generate clicks or impressions such as paid-to-click, paid-to-surf, autosurf, and click-exchange programs, or any deceptive software. Please note that clicking on your own ads for any reason is prohibited. Failure to comply with this policy may lead to your account being disabled.
Encouraging clicks

In order to ensure a good experience for users and advertisers, publishers may not request that users click the ads on their sites or rely on deceptive implementation methods to obtain clicks. Publishers participating in the AdSense program:

* May not encourage users to click the Google ads by using phrases such as "click the ads," "support us," "visit these links," or other similar language
* May not direct user attention to the ads via arrows or other graphical gimmicks
* May not place misleading images alongside individual ads
* May not promote sites displaying ads through unsolicited mass emails or unwanted advertisements on third-party websites
* May not compensate users for viewing ads or performing searches, or promise compensation to a third party for such behavior
* May not place misleading labels above Google ad units - for instance, ads may be labeled "Sponsored Links" but not "Favorite Sites"

Site Content

While Google offers broad access to a variety of content in the search index, publishers in the AdSense program may only place Google ads on sites that adhere to our content guidelines, and ads must not be displayed on any page with content primarily in an unsupported language. View a list of supported languages.

Sites displaying Google ads may not include:

* Violent content, racial intolerance, or advocacy against any individual, group, or organization
* Pornography, adult, or mature content
* Hacking/cracking content
* Illicit drugs and drug paraphernalia
* Excessive profanity
* Gambling or casino-related content
* Content regarding programs which compensate users for clicking on ads or offers, performing searches, surfing websites, or reading emails
* Excessive, repetitive, or irrelevant keywords in the content or code of web pages
* Deceptive or manipulative content or construction to improve your site's search engine ranking, e.g., your site's PageRank
* Sales or promotion of weapons or ammunition (e.g., firearms, fighting knives, stun guns)
* Sales or promotion of beer or hard alcohol
* Sales or promotion of tobacco or tobacco-related products
* Sales or promotion of prescription drugs
* Sales or promotion of products that are replicas or imitations of designer goods
* Sales or distribution of term papers or student essays
* Any other content that is illegal, promotes illegal activity, or infringes on the legal rights of others

Copyrighted Material

Website publishers may not display Google ads on web pages with content protected by copyright law unless they have the necessary legal rights to display that content.

CTR Tips

CTR is your click through rate.

If your overall site wide CTR is higher than 5%, then you are doing things right.
If you are below 3% you definitely have some improvements to make.

You want your ads to be related to your site. If they are off-topic the people searching your site probably wont click on them.

Here are the tips:

Create one topic per page.

Mark some of your keywords in bold or italic.

Use your keyword in your page title.
