   With all the recent hoopla of Google's algorithm changes, specifically about sites that may be penalized for over optimization discussed by Matt Cutts of Google, we just have to make sure as Internet marketers and webmasters that we implement a few changes. I would not do a whole site overhaul unless you think your site really needs it, for the most part if it is working for you now and it is not broke don't fix it, just fine tune it! Here is the Audio Link: Google Over Optimization Penalties.

From listening to the audio clip I get a few great tips which I already use here at JavaScripts and More.

• Links on page: Create links that lead to more information and make those links within correlation.
  
• Unique Content: Create unique content that is found no where else on the internet.
  
• Social Engagement: Use Social networks to promote your content and create social buzz that people talk about. This creates unique and new content for the search engines to take in.
  
• Ad Placement: Place most of your ads below the fold. What Google wants is a better user experience and way to many ads will give an impression of a company looking to make revenue rather that providing useful content.
  
• Avoid Redirects: When someone lands on your page do not immediately send them to another page. These pages with redirects are not good user experiences.
• Buying Links: If you are going to buy links make sure they correlate to your site and that the links are descriptive

I have a few techniques I use here on this site to help my rankings.These tecniques I use work for this site and I have seen the traffic jump drastically and I'm sure by implementing some of these techniques you will also see more targeted traffic.

Correlating Sites: I create blogs from WordPress, Blogger MyOpera and such with links that correlate to each page on my main site. These sites are for informational purposes only and are descriptive with links that include the topic to each page of my main site.

Social Sites: I use Google+, Facebook, Twitter, Pinterest, Chill.com, Zurker and a Stumbleupon just to mention a few to promote my pages. I create contests and usefull content that teaches or gives tips on certain topics that people will like, re-tweet, re-pin(include additional links in your pins to your site) and share to create a viral lift.

Deep Linking: Deep linking will show up in Google's results as additional links below the main result for the search query. make these deep links descriptive and have the same title that matched the page you are linking too. If you have pages that you think are more important, don't put those links no farther 1 to 2 clicks from the main page, this will tell Google about he importance of those links and establish hierarchy.

Tags: Use tags to describe your page by using keyword variations and try to use them within your content on the page.Bookmarking Sites: use these sites to create bookmarks and make them public and descriptive pointing to your site. Google still uses links to rank your site, and when you have popular sites that link back to your pages this gives some of that authority to your pages.

Long Tail Keywords: These type of Keywords are more descriptive and easier to rank for. They can produce more targeted traffic and with Google's new Semantic Search, these types of Keywords will make a big difference in rankings as Google will better understand what the user is searching for.


Additional Resources 
Google has also released a video of a Search results quality meeting with some points to follow: 

In Closing, I would like to take a minute and discuss why you should not be to worried about over optimizing. Take a look at these other big sites like delicious.com, Digg, StumbleUpon and Social Bookmarking sites. These sites most likely will not be penalized even though they are rich with keyword content using cloud tags and categories that have single keywords and key-phrases.

  They have content that is constantly fresh, the sites have been around for a long time, their social engagement is astronomical and they give value to a good user experience. Like I said above, I would not do a site overhaul unless it is giving a bad user experience and is not offering unique content that cannot be found anywhere else on the internet.

Everybody knows about Pinterest by now. However there are certain things you can do to increse the traffic to your site using your pins.

  When I visit a site and see a infographic I pin it. I include a catching description of the pin and I also include my link to my website just below the description of the pin as a related link.Pinterest users that follow you or search for the same interests, will re-pin that infographic and included is your link in the description.

 Now that facebook has integrated Pinterest into the timeline, you can get more viral traffic from your url as the re-pins will show up on the Facebook profiles of whoever re-pinned the infographic you originally pinned or re-pinned. Don't forget about Twitter too! when your followers tweet or re-tweet your pins this also creates more traffic.

 If the infographic has a good title and description, you can add in the url to a certain page on that particular subject and reap the benefits of SEO by correlation.

Google Alerts Allow you to create alerts about any subject and shows you the newest results. You can create specific alerts and have them sent to your e-mail.

Creating Specific Alerts allows you to keep up to date with the latest information on what's going on in a particular Subject. Whether you want to create an alert for your name or your niche Google Alerts will show you the latest news.
  I created a Google Alert for HTML 5 Articles. This is how I find out about the latest developments in HTML 5 news. I can follow all the links and read up about HTML 5. I always note certain points when I visit each site.

• Unique Content: Since Google Alerts show new content I rarely have to worry how new it is however it can be a new post on a old subject so I read it over carefully and follow links contained within in case they point to references about the work and I can determine how new the content really is.
  
• Link Building: I always look for a way to add some valuable information so I can drop a link to my specific page that correlates to the subject on Forums and Blogs. ( especially  if they mention your name or business) you can drop them a thank you for the mention.
  
• Pagerank-Alexa Rank: I check out the Google Pagerank and Alexa rank to see if this would be a good place to drop my link, in return get some link Authority and possibly more visitors
  
• Contact Info: I always note the Author or Webmaster as I may want to trade links or buy advertising at some point. Also the Author may write Articles for my Specific Alerts that I may have set up as they may be an expert on the subject. Ask them if they may want to Guest Blog or write you an Article.
  

Now to get back to setting up the Alert's you have to have a Google Account and  then login.

Search Query:In the search Query Field is where you want to put in your Keywords or keyphrase, you can put Quotes around the query to receive the exact search term

Result Type: Select the drop down menu and select what type of results you want to see whether it be Everything, News, Blogs, Videos, Discussions or Books.( Good for Link Building)

How Often: Select whenever you want to receive the Alerts, As-it-happens, Once a day, or Once a week.

How Many: Only the best or All results. Only the best will give you the latest and most relevant results for your query. All results will give you everything.

Deliver To: Deliver to your E Mail address or an RSS feed.

  Now you want to drive traffic to your Content right? there are a few steps I do to market my content.

1. Headline: I make a good headline that easy and short. These headlines are in the URL and generally give a good point to the subject.
2. Screen Shots, Info-graphics: I take a few Screen Shots and post them up with tags showing examples and this helps add to your content. Pin these to Pinterest and Chill.com
3. Socialize: I then Socialize my content by posting to Google+, LinkedIn, Facebook, Twitter, Zurker, Pinterest and Chill.com for Videos.
   
4. In Closing: I write about what I think about the particular content and look towards the future improvements and how it can benefit marketers like myself whether it may be positive or negative.

  In closing I think Google Alerts has shown to be a valuable tool for Internet Marketers and Webmasters alike. Goolgle has many more tools you can use to keep up to date on the latest topics like Google Trends.
  There are so many ways to do effective Content Marketing, finding the ways and keeping on top of the latest news, tips, Discussions and strategies can be a daunting task, however Google is making it easy for Internet Marketers to follow the rules by making and sharing more tools and Google Alerts is one of many I use to make Content that drives in targeted Traffic with little to no investment in advertising.
