1. Original, Fresh Content
Content is king in the web world. People visit websites for the primary purpose of finding content, so make sure you deliver. Website content should be unique and up to date. Fresh content will keep visitors and search engines coming back for more. Don’t forget to proofread!2. Target Audience
From a quick scan of your website, visitors should be able to determine what you offer and how you can benefit them. A good website will have headlines and text that speaks to the target audience’s needs and wants. Many websites simply list what their company does without saying how they can benefit their target audience. Keep your audience in mind when designing your website to be sure that it will appeal to them and encourage them to take action (whether that is to submit a contact form, signup for a newsletter or buy a product).3. User-Friendly Navigation
A good website has content that is easy to find. Pages should be organized and named in a way that the target audience will easily understand. For instance, a services page would be better labeled “Services” than “Business Solutions.” Keep your navigation consistent from page to page to avoid any possible confusion. Double check all your links to make sure they are working. Make sure that your most popular content is no more than a click away from your homepage. If your website has a lot of content, provide a search box so visitors can quickly find what they are looking for.4. Simple and Professional Design
A good website will have an attractive layout that is easy on the eyes. Be sure your colors contrast well and your text doesn’t require a magnifying glass to read. Personally, I can’t stand reading large amounts of content written in white on a black background. It strains my eyes. Reducing the contrast a bit can help (light grey text on dark grey background).Lots of text can overwhelm a user. Breaking up text into subheads and bullet points will improve the layout of the page and make the text more scannable. No one has time to read every word on a page.
Use design elements to draw attention to or to enhance the content of a page. With every design element added, take a step back and make sure it serves a purpose and does not detract from the usability of the site. Put things where users expect them to be. However, do try to make your website look unique. Just remember that simple, professional design will be much more effective than flashy, overcrowded design.
5. Speed
How many seconds will you wait for a page to load before you give up and leave a website? Many factors can affect the loading time of a website including coding, number of graphics, the server speed, traffic volume on the website and the capabilities of a user’s computer.Make sure your server has the proper amount of space/bandwidth for your website and that your website code is lightweight. Use large graphics sparingly. Use CSS styles in place of graphics where possible. Waiting for large graphics or a fancy flash animation to load on each page will surely turn away some visitors.
6. Search engine optimization
SEO is one of the most commonly neglected aspects of a website, but a website is useless if no one can find it. Think about the keywords that users may search for to find a product or service you offer. Do some research to see how often those keywords are searched for through a tool like Google’s Keyword Tool. Use keywords in titles, meta tags, headings, file names and in the content of your site. Search engine optimization can mean the difference between getting 500 visitors a month and 500 visitors a day.7. Link building
Links are an important factor in determining where your website appears in search engine results. Find as many legitimate sites as you can that will link you your website. Add your link to your business profile in directories like Google Local, Yahoo! Local, Merchant Circle, Insider Pages, Yellow Pages, LinkedIn and more. Submit articles and PR to sites that will include a link back to your website. The best way to get links to your site, however, is to provide unique and interesting content that people want to link to. You can make it easy for them to share your content by providing links or buttons such as the addthis.com button.8. Tracking
A good website is a work in progress. A nice tool like Google Analytics will keep track of the number of people who come to your website, what pages they viewed, where they came from, what keywords they used in search engines, how many left after the first page and more. Unlike other media, websites can be easily tracked to see what is working and what isn’t. This data will help you to improve the quality and structure of your site.Bias information
Systemic error resulting in an inflated or deflated effect estimate occurring when the measurement of the risk factor or the disease is systematically different between the groups being compared.
Information bias leads to misclassification with respect to the disease or the risk factor. Diseased people may be classified as non-diseased and vice versa.
Exposed people may be classified as non-exposed and vice versa.

Examples..Women VS Men :10 Differences that make difference
When it comes to health, there are many crucial health differences between men and women. Yet many women do not know that they react differently to some medications, are more vulnerable to some diseases, and may have different symptoms. The Society for Women’s Health Research brought attention to sex differences in initiating the groundbreaking 2001 Institute of Medicine report, Exploring the Biological Contribution to Human Health: Does Sex Matter? The report underscored the need to better understand the importance of sex differences and translate that knowledge into improved medical practice and therapies.Following are some quick but vital facts about sex differences in health care that you probably did not know.
Heart Disease – Heart disease kills 500,000 American women each year – over 50,000 more women than men – and strikes women, on average, 10 years later than men. Women are more likely than men to have a second heart attack within a year of the first one.
Depression – Women are two-to-three times more likely than men to suffer from depression in part because women’s brains make less of the hormone serotonin.
Osteoporosis – Women comprise 80 percent of the population suffering from osteoporosis, which is attributable to a higher rate of lost bone mass.
Smoking – Smoking has a more negative effect on cardiovascular health in women than men. Women are also less successful quitting smoking and have more severe withdrawal symptoms.
STDs – Women are two times more likely than men to contract a sexually transmitted disease, and more likely to experience significant drops in body weight, which can lead to wasting syndrome.
Anesthesia – Women tend to wake up from anesthesia more quickly than men – an average of seven minutes for women and 11 minutes for men.
Drug reactions – Even common drugs like antihistamines and antibiotic drugs can cause different reactions and side effects in women and men.
Autoimmune Disease – Three out of four people suffering from autoimmune diseases, such as multiple sclerosis, rheumatoid arthritis, and lupus, are women.
Alcohol – Women produce less of the gastric enzyme that breaks down ethanol in the stomach. Therefore, after consuming the same amount of alcohol, women have higher blood alcohol content than men, even allowing for size differences.
Pain – Some pain medications (known as kappa-opiates) are far more effective in relieving pain in women than in men.
