SEO – Duplicate Contents

January 21st, 2010

I have been increasing my understanding of the Duplicate contents and its effect on Search Engine Result Page (SERP) by way of some experimentation. To understand why should google not like the duplicate content – consider a hypothetical case where I am a blogger and I have 10 blog domains. With $10 an year it is really not difficult to get 10 domains. Now I write one unique article and assume that the keyword  I choose is such  that it results in only say 10,000 pages and its is easy to bring it to top in google. So I write one unique article and it comes to the top in the google. Now I have 9 more domains. So I go on and copy paste MY article on the 9 domains with more or less the same content. I apply the same SEO techniques and bring all 10 of them of page 1 and page 2 of google.

What this results in ? A search with the keywords results in pages that are all same in content. The google users will certainly not appreciate it. They would have liked different pages in the 1st and second pages. And precisely for this reason, google does not like the duplicate contents.

In many cases google will index only one page if you have multiple contents of about the same content. I experimented it with the following two blogs that had the same contents. There are only minor changes.

http://referencedesigner.com/blog/fujitsu-lifebook-mh380-netbook-review-seo-experiment-1/712/

Both these pages were optimized for the keyword “fujitsu lifebook mh380 netbook review”. I found that google results only one page in the search result even though same number of the backlinks were created.  Was this also because both the pages were on the same webite ? To examine this I wrote another blog at

http://janatanews.com/2009/dec/Fujitsu-Lifebook-MH380-Netbook-review.php

This blog too, had mostly the same content. I had expected it to come somewhere in the search result. It did not. That makes me conclude  that

“Write original contents. Do not copy contents. It will not help you in SEO. You will not be able to rank high in search result.”

Note that, I am not yet considering the ethical practices of copy paste. They have their own implications and you can be caught for copyright violations for copying someone else’s contents. It is therefore imperative that you make it a habit of writing original contents in your blogs or website contents.

There are some finer points as well that you must pay attention. Assume that your webpages has a long disclaimer at the end of every page on your website. If that is the case and the actual content on the webpage is relatively small, then google can think that all pages have similar content ( the disclaimer), and may therefore mark pages at duplicate page. It is therefore necessary to keep the common content of the webpage to bare minimum. And if you need to write a short description with a url to the complete content.

Canonical url yet another topic that needs to be understood in this context. Probably in some other blog.

Making Healthcare Affordable – Bilirubin treatment example

January 21st, 2010

US medical system is under financial strains with high cost associated with the doctor fee, hospitalization charges, high medical equipment cost, soaring medicine cost. A typical insurance premium for a 4 member family in United States is in the vicinity of $1000 ( give or take a hundred dollars). This is beyond the affordability for most of the middle and lower income US families. If their employer or the State do not provide assistance, this will simply mean the they will have to be without medical insurance.

On the macro level, a number of policy decisions need to be made to make  health insurance more affordable for individuals, businesses and government. On Micro level, a number of small things can increase the cost efficacy of  the treatment plan and reduce the cost of the treatment. In today’s blog I will write about how to reduce the cost of Bilirubin treatment in neonatals.

How is Bilirubin Treated for Neonatal

Noeborn kids remain at Hospitals typically for two days for the treatment of Bilirubin. Typical cost to the patient or the insurance companies vary from $3000 to $5000. The treatment itself is surprisingly simple. It needs just the ultra violet radiation in controlled and measure fashion for about 48 hours to treat most of the bilrubin patients.

How can the cost be reduced

The excessive cost is resulted because the patient need to be at the hospital for two days. The cost is escalated due to the stay which involves nursing, cleaning, food and lodging along with the medical treatment. All of this can be avoided by not requiring the patient to be admitted to the hospital. The patient should be handed over a portable ultra violet emission device alongwith a method to measure the bilirubin by himself, in the same way blood glucose is measured.  The portable ultra violet device can be returned by the patient to the hospital at the end of the treatment. The patient should be instructed how to use the ultra violet emission device.

The method should be used for all non serious cases of the bilirubin. For all advanced cases of bilirubin, the patient should be hospitalized and the traditional method should be used.

A Low cost Ultraviolet LED Solution

Light emitting diodes (LEDs)  operating  in the 410 – 490 nm wavelength range (peak at 475 nm) have been developed. These gallium nitride(GaN)/sapphire LEDs can produce high irradiance with very low power requirements suitable in the ultraviolet spectrum. These LEDs emit  ultra violet light within the peak absorption range of bilirubin.. They promise to be low cost, portable and have long operational lifespans.

Bilirubin Detection – Pathological Advancements

Current practices in pathalogical diagnosis of Bilburin requires a large volume of the blood sample from the patient.  Several newer methods have been develped that will require smaller blood sample.  These memethods acquisit the current signals produced from bilirubin by an electrochemical sensor. Requirement of the smaller blood sample is another research area that need investigation and implementation.
