YII is a free open source web application development frame work written in php5. It has the extremely optimized performance and it is a perfect choice for any kind of projects. Its high and impressive performance while comparing with other PHP-based frameworks immediately drew very positive attention. Its popularity and adoption continues to grow at an ever increasing rate.

YII is the fastest PHP frame work best for creating large scale Web2.0 applications. YII can be used for developing any kind of web applications. It is especially suited for high traffic web applications like portals,forum, social media sites and so on. The name YII(pronounced as ‘yee’) is the abbreviation of “Yes It Is”. Obviously it is the answer for the questions like:

Is it fast? … Is it secure? … Is it professional? … >> Yes, it is!

Why YII?

YII has the features like MVC,DAO/ActiveRecord,caching, authentication and role-based access control, scaffolding, testing and so on. It is light weight and has powerful caching support. Security is a part of this frame work. It includes input validation, output filtering, SQL injection and Cross-site scripting prevention.

YII is much faster because it is using lazy loading technique. It does not enable a functionality until or unless that has been invoked for the first time. For example it does not create an object unless the object is called for the first time. Other frameworks suffer from the performance hit because they would enable a functionality no matter it is used or not during a request.

1. Performance.

YII has the extreme performance compared to other frame works. The YII team have generated a statistics for the performance of different frame works based on “request per second” which describes how many requests an application written in a framework can process per second. From the graph given below the RPS is for “request per second”. The higher number shows the higher performance level of the frame work. The performance is significantly high when we enable the PHP extension APC.

2. Security.

Security measures like Cross-site Scripting Prevention, Cross-site Request Forgery Prevention and Cookie Attack Prevention are enabled. Also YII includes client side and server side validation. We can just enable or disable the validation rule. It is not required to write separate validation rule for the inputs like other frameworks. YII has built-in authentication support. It also supports authorization via hierarchical role-based access control.

3. Best Caching features.

YII provides various cache components to store cached data in different media. While comparing to other frame works YII has an excellent caching system. YII supports memcache, APC, XCache and DB based page and segment caching.

4. Friendly with third-party code

YII is also designed to work with third party codes. You can use code from PEAR or Zend Framework in your YII application.

5. Easy to extend / customize

It is very easy to edit or customize the YII based applications, since it has a very simple code structure. You can also use different kinds of extensions and widgets as per the requirements.

YII is purely object oriented, architecturally clean and very simple to extend it. If you are not experienced with the PHP frame works and want to develop some simple applications, then maybe you should try an easier framework. I recommend to everyone who knows object oriented programming should pick up YII and try it once.

Adwords is an advertising system that allows you to buy links on search engine results pages. Google AdWords is by far the most popular and widely used Pay-Per-Click (PPC) service currently used. Cost-per-click (CPC) bidding allows you to set a maximum price on the cost of someone clicking on your AdWords ads. This means that your ad runs for FREE until somebody clicks on it. You ONLY have to pay when somebody clicks your ad.

Selecting keywords is the most important part of any Adwords campaign, as well as other internet marketing campaigns. This is what will bring people to your site who are searching for what you sell. Also look for keywords that are not really that competitive at first or you will exhaust your budget quickly.

1.Think like a customer when you create your initial list

Write down the main categories of your business and the terms or phrases that might fall under each of those categories. Include terms or phrases, your customers would use to describe your products or services. Be more specific, while choosing the keywords.

2.Set a budget for keywords

AdWords has a very clever feature which allows you to set a daily budget. So first set a budget and then carefully check on the needed keywords.

3.Use the Keyword Tool to find and select new keywords

You can get keyword ideas by using the Keyword Tool. Take the list of keywords and put it into Google’s Keyword Tool.

Google will show you how many people are searching for your keywords every month, and how much advertiser competition there is for that word. It will also generate a bunch of additional keywords that are related to the ones you already put in. If you go down the list, you may see some good ones that you didn’t think of yourself.

Ideally, your best keywords will be the ones with the most searches and the least competition. The less competition your keyword has, the cheaper it will be to run an ad on that keyword.

4.Carefully observe the competition

Make sure you research what your biggest competition is doing, and take full advantage of that information. Is a particular keyword effective for them? What market are they targeting with their keywords? All if this information can help you determine which AdWords strategy will work for you.

5.Optimize and use a relevant landing page

When a person searches for one of your products or services, don’t have the landing page associated with that keyword be your homepage. It is much more useful to have them lead to the relevant page, so that the searcher finds what they want as quickly as possible.

Use limited good keywords and configure manually CPC , Choose perfect add location , not whole world target specific location and then enjoy the benefit.

If your website is new to search engine optimization and you don’t know which keywords will draw higher conversion rates, you can quickly test the popularity of different keyword phrases using Google AdWords campaign and later specialize in more popular ones for organic search.

The above is a very rough outline on google adwords , if you have any questions, we would be happy to talk to you!

Have you ever dreamed of building a website that interacts well with visitors, without having to hire the expertise of a scripting veteran? Have you ever imagined a User Interface performing well across all the commonly used browsers, that competes with the effects and interactivity of a flash driven website, all being delivered to you by a mediocre programmer without much scripting knowledge? If you have, then jQuery is what your looking for!
