Tips for Better Searches Keep it simple. Describe what you want in as few terms as possible. Use descriptive, specific words. Avoid general or common words. Think of how the page you want will be written. Use words that are likely to appear on your ideal page. Tips for Better Searches
Stop and think for a moment about what your perfect answer will look like: 1. WHO cares about what I care about? Who do I trust to give me the information I need? 2. WHAT words would I use to describe it, what words would my trusted source use? Which would be most common? 3. WHERE would my trusted source publish this information? 4. WHY would someone use one format or another to communicate this information? 5. HOW will I know when I found what I want?
Are there any concepts that describe what you want that would actually appear on the page?

First ask the question who is the author? If you don’t find one, turn your skepticism meter to the top of the dial. Use to find out who owns the sites If the author name is listed, do a quick search on it to evaluate what others think of her/him. Scan The URL of the website. The URL is the web address of the page you are reading. It has this format:www.name of the website.name of article you are reading.com. This is the first door we need to tap in to get a glimpse of what the article is all about. Read the URL carefully and look for the following: Does the URL have a domain name and if so is it appropriate for the content? You should know that a site that has a domain name ending with.edu is more likely to be relevant for academic and educational content. Check out if the page is dated and if so, is it current enough? Undated factual or statistical information is no better than anonymous information. Be cautious when dealing with it. Look for indicators of quality information: are sources documented with footnotes or links? Do the links work? Are they reliable? If the article is reproduced from another source then is it complete, not altered, fake, or forged? Try to figure out the purpose of the website? Is it mainly commercial? Is the author trying to generate revenue by recommending things, enticing, or selling products? Is the website informative and provides data and facts? Use Google Page rank.This is a sophisticated algorithm Google uses to classify websites from 0 to 10 with 10 being at the top. Any webpage with a Google Page rank of 5 upwards is likely to be more reliable. Use Alexa Traffic rank (www.alexa.com). This is another useful tool to rank websites. Alexa ranks websites according to their backlinks and pageviews. It starts with 26 million down to 1 with 1 being the top ( Google has 1 in Alexa rank ). Any website ranked from down might is likely to be reliable.
