SEO is an acronym for "search engine optimization" or "search engine optimizer." 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. Make sure to research the potential advantages as well as the damage that an irresponsible SEO can do to your site.

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!
