Deciding to hire an SEO is a big decision that can potentially improve your site and save time, but you can also risk damage to your site and reputation.

Time sure flies! We’re coming up on another year end and, with that, we’d like to take a step back to review our AdSense highlights of 2012.
With your feedback in mind, we made updates to the AdSense interface including a refresh to the Ad review center and the ability to add multiple users to your account. We also introduced more reporting features, a new look to Performance reports, and enabled you to manage your account and block ads directly from your site with the new Publisher Toolbar.
You asked for more tips to help increase your revenue, so we showed ways to improve your site by using social tools, going mobile, making user experience changes, and using DoubleClick for Publishers Small Business. Many of you reported revenue uplift (up to 400% for some!) after implementing specific changes recommended through an email or the AdSense interface.

We had the opportunity to connect with many of you through our AdSense in Your City events (now called Learn with Google for Publishers), and through our newly created AdSense +page. We’d love to continue these interactions, so be sure to opt in to receive special offers, and follow our AdSense +page for the latest updates and Hangouts.
You let us know that you value hearing from other publishers, so we highlighted publisher stories throughout the year, including Philip Martin, who became an artist with the help of AdSense.
We made the payments process easier by updating the look of the Payments page in the AdSense interface and by extending payment options in Southeast Asia.
We introduced changes to ad formats to provide you more options and increase your earning potential.
You also told us that improved communication around the AdSense policies are important to you. We reviewed policy resources, provided some tips and announced ways we can work better together.
And finally, following our annual tradition, we’re happy to reveal our most visited blog post of the year: the announcement of AdSense availability in Indonesian. Please keep +1’ing our posts to let us know when you like them and also +1 our blog in the upper right-hand corner if you’re a fan.

It was a busy and fulfilling year working with you, our dedicated publishers. Stay tuned for updates on future improvements. Happy New Year 2013!

 Optimize the below three for better SEO:

• Meta Tags
• Navigational  links
• Rich Content

Meta Tags:

Meta Tags are very important for your website's visibility. Many search engines read them from your site when you submit it to them .Major meta tags that you can use:

Meta Title,
The only resource type that is currently in use is "document" This is the only tag that you need to put in for indexing purposes.

Meta Description,
Depending on the search engine, this will be displayed along with the title of your page in an index. "content" could be a word, sentence or even paragraph to describe your page. Keep this reasonably short, concise and to the point.

Meta Keyword,
Choose whatever keywords you think are appropriate, seperated by commas.

Navigational  links:

             At the right or at the bottom, but not on the left, of the page.  When the search engines "read" your site, they read from the top left to the bottom right.  Search engines place an emphasis on the first 100 words or text on the site.  You do not want these words to be navigational links or Javascript.  Ideally, you want to have your heading tags with your keywords in the beginning of your page.  This being said, placing your links/JavaScript on the right or bottom of your page ensures the search engine spiders get to the text first, giving more weight to what's important on your page.


Rich Content:

             The more content you have on your site the more likely someone is to find what they're looking for when they get there. Keep your site very content rich. Have a lot of pages.Update the site even twice a day if you have the time. Updating your site does not mean that you copy paste content from other sites.That will only push your rankings further down. Don't have any duplicate content. At the same time ,dont spam multiple content across the same website. When a search engine views or reviews a website, which they do at least every few months, it looks for specific characteristics found in the content of website landing pages.
