For those of you who are not familiar with the term, a CAPTCHA is a feature on many user populated websites, such as Myspace with the purpose of blocking automated programs from spamming its users and for overall security. Here is how it works:
A user is required to enter a random letter and number password into a form before being able to submit information, log in, etc. This password is essentially given directly to the user in an image, rather than in text form, so that an automated program cannot detect the characters. The password the form field expects is the same as that shown on the image, but this sometimes causes problems.
Jeff Atwood at the Coding Horrors blog discusses whether CAPTCHAs are dead. This follows a news report that scalpers probably beat the CAPTCHAs at Ticketmaster.
Jeff links to a Chinese site that sells CAPTCHA decoders. The site quotes different prices for breaking different CAPTCHAs. An eBay decoder, for example, is being sold for $4000 and claims 70% accuracy.
What caught my attention were the unbreakable CAPTCHAs in the list. The Yahoo CAPTCHA is listed as unbreakable. That isn't surprising. Most of us can barely get it right ourselves.
Consider a Yahoo CAPTCHA. Sometimes you cannot tell the difference between a G or a 6? And the way that letters are often skewed, the difference bewteen certain uppercase and lowercase letters is virtually unrecognizable?
Contrast that with a Google CAPTCHA also listed as unbreakable. The Google image is clean and legible. Most of us have no difficulty getting it right. Google demonstrates that effective CAPTCHAs don't have to be unfriendly to users.
I am curious to learn which CAPTCHA libraries generate strong, yet user friendly challenges.

R6You have a business, and ever since you started the SEO campaign, business has been good and most of your business enquiries have been coming via your website. You are getting professional SEO support and an ongoing SEO program takes care of all your SEO work.They have optimized your website and now it attracts a fairly good quantity of relevant incoming traffic which has been resulting in good business enquiries and sales. Now, suppose you have other competitors for your business in your region and would like to know if your competitors also have an SEO campaign going on with their website. As you are ignorant on this issue it has been making you anxious. They have always been your stiff competitors so you can't just call them up and ask about it! So what do you do?
Ok, if you want to find out about your competitors are also optimizing their website it is a very simple process to find it out. It is not necessary for you to send some one out to spy on your competitors to get this information because it will only take you a few minutes to find out and confirm this information online. All you need to do is just go to your competitor's website and check on its HTML source Code!
This is how one should go about it. Go to the concerned web site's homepage on the browser and click on "view" and choose "source" and the HTML source code page opens up. If you are using Internet Explorer 2.x, right-click on the web page, and then click View Source. To view the HTML source code for a web page that contains frames, right- click the web page in a frame, and then choose "view source". Looking at this page you will be able to get the required information.
On this HTML source code page, just see if there are main keywords in the header tags KEYWORDS , the title tags

A4There are many advertising options out there for small and large businesses alike. A new phenomenon that has recently hit the scene is the use of sponsored link searches for advertising needs. Are sponsored links really the best way to allocate valuable advertising dollars?
A re occurring complaint I hear from many of my customers is that sponsored links are not developing the return on investment they desire. There are several key reasons to why this may be occurring. Sponsored links, or pay per click advertising, are links on the right hand side of most search engines. These links, historically, are only used by approximately 30% of the online search market. By using only sponsored links in your online marketing campaign, you have essentially cut out 70% of the market that may be searching for your business. Further, did you know that there is a constant bidding war on the sponsored side of the page? Business are having to spend valuable working time managing their sponsored link page to make sure the are staying on the first page, while not breaking the bank. Because most consumers don't search past the first page of search engines, it is a constant war to "out bid" your competitors and stay in those valuable spots. But what is to keep your competitors from clicking your links and costing you tons of money and headaches? Thankfully, Google (among others) have allowed you to set certain limits on the amount of money you wish to spend monthly on sponsored link searches. While pay per click ads may get you some form of business, I do not believe they are the end all in online marketing. It is important to recognize several key factors when thinking about investing in pay per clicks.
1) How can I minimize "fraudulent" clicks by my competitors
2) Are their other online options, for around the same cost, which can give me a better return on investment? and
3) Am I willing to cut our 70% of the search market by spending money on sponsored links?
For some businesses, pay per clicks work. I am not advocating that they don't. The law of "big numbers" may come into play here where if you do something long enough, the average return will be worth the investment. I have found other advertising mediums that allow my customers a better, more stable, return on their investment. Diversity is the key to the marketing game and in order to advertise to all corners of a market, it is necessary to weigh your options and decide if you have the time, and money, to play the "big numbers" game.
