Credibility refers to the trustworthiness of the information. If the evidence you use is false, than any argument you make will also be false.
Currency: the timeliness of the information
Relevance: the importance of the information for your needs
Authority: the source of the information
Accuracy: the reliability, truthfulness, and correctness of the content
Purpose: the reason the information exists
By scoring each category on a scale from 1 to 10 (1 = worst, 10=best possible) you can give each site a grade on a 50 point scale for how high quality it is!
45 - 50 Excellent | 40 - 44 Good | 35 - 39 Average | 30 - 34 Borderline Acceptable | Below 30 - Unacceptable
Reading a text in isolation can be dangerous. Thinking about evaluating sources as "good" or "bad" is misleading. There is a lot of grey and information is all about CONTEXT.
The way information is created today is interconnected and complicated; context is the key to understanding the credibility of the source. When you incorporate lateral reading into your process of evaluating a source, it encourages you to dig deeper to see the bigger picture and to wonder about how this source is interconnected with others. When you're properly evaluating a source, you're not just wandering around looking for an article to use for your paper, you're wondering about uncovering any bias within the source and how it fits within context of your knowledge, research, and purpose.
Lateral reading means you spend less time on the source you're thinking of using and more time searching for information about the source. Instead of going to the About Us page of a website to learn about the organization you've never heard of (vertical reading), you'd open up a new tab and search for other sources about the organization, it's founders, and it's reputation (lateral reading).
There are plenty of organizations that have a veneer of authenticity and neutrality as a disguise for advocacy or lobbying and plenty of publishers that have leaning agendas that won't ever run a story that doesn't support the narrative they want to portray. Lateral reading encourages you to ask many of the 5 W's (especially who, what, why) with the underlying goal of discovering "what sort of public memory does this information invoke?". These steps help you understand the context of the source, uncover nuances and subtle signaling that only are revealed through critical thinking.
Instead of asking whether this is a "good source" or a "bad source" ... you're asking "why would I use this source" and making your decision based on the context you've uncovered.

Stop: Understand who created this information and why
Investigate the Source: Know what you are reading before you read it
Find Better or Other Coverage: Look for other reporting or analysis on the claim

There are many methods for critically considering information resources. One is Joseph Bizup's BEAM model.
The BEAM method is especially helpful when deciding how to use a resource.
B: Background Background information is general information or factual evidence used to provide context
E: Exhibit Exhibit or Evidence are materials you can analyze or interpret
A: Argument Argument information comes from critical views from other scholars and experts. You can engage with these claims to become part of the scholarly conversation. You can refute, refine, extend, build upon, or affirm them.
M: Method Method information refers to the methods or theories used by the author to analyze and interpret the evidence. You can use these to adopt a concept, a work process, or a manner of thinking.

When looking at an information source, try asking yourself the Five W's.
Be aware of your own biases, look at the credentials for the author, fact check.
Facts About Websites
Commercial websites (.com) may contain useful preliminary information, product information, and links to other websites. Remember that commercial sites are attempting to sell a product; therefore, the information may be biased.
Educational websites (.edu) are maintained by universities or other educational institutions. They are created with the idea of providing information that will be helpful for students and faculty. Usually, the webmaster has previewed the information and the links included. However, you should always evaluate these pages critically before using them. Be aware that student assignments and projects may be located on .edu sites.
Government websites (.gov) are provided by all departments of the Federal government. They contain a wealth of information on a wide variety of subjects. Government sites are also excellent sources of statistical information that is often easier to find electronically. Standard evaluation criteria should still apply.
Organizational websites (.org) are sponsored by non-profit entities. Most have good information and contain excellent links. Remember to evaluate each page on its own merits. Because many organizations have their own agendas, information from these sites may also be biased.
Country and state websites (example: .us or .ks) may have a two-letter domain name. These sites may have very useful information. However, all information should be evaluated.
Other domain names may be located in web addresses. Remember to use the same criteria to evaluate all sites.
