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.

A4There are many small business owners doing ecommerce online who are struggling, trying to increase their top page rank ratings. This is very time consuming and expensive. A lot of ecommerce businesses do not have a budget to allow them to take advantage of link buying, or other endeavors to increase the page rank ratings they need to make the money the big guns do.
How do you build a website for PR0 to PR2?
Here are some helpful hints that will work for you to get a top page rank on Google.
Get a private domain name. This is essential in this business. Be online for a few months. Make sure you change your content regularly, at least once a week. Have at least fifty inbound links that work.
This next step is tricky but not difficult. Have between 50 to 100 plus articles on your site. Submit your website to all of the necessary directories. Begin to link your website in the forums. Become a member of Google's PayPerClick Program. Google will welcome you with open arms. You invest twenty dollars to join Google's PPC program once. Done correctly, you will get back this small investment within a few short months.
It is a wonderful idea to make friends with Google. It is the number one search engine right now. Google's index spiders search the internet, finding sites to rank them against relevance. This takes some time for the spiders to do their job, sometimes up to several months, so have patience because it will take a few months for your site to get indexed.
A page rank of 5 can be reached by generating at least 10,000 links. This sounds daunting but it is not impossible. When you have 200 pages of content with each page having thirty or more links to other pages, those inside links will generate 6,000. Google's spiders will count the links inside the site because the size of your website is just as important as the links inside of it. This is especially valid when all of your website's content is alike.
This method will work for you, but you will have to be patient and allow some time to pass. Give it a few months, then begin checking at Google to see where your page rank is. From here, you will have a good idea in a few weeks if it is moving up, or down in page rank. If it is moving down, then you need to tweak your site, or adjust the keywords and keyword phrases.
