Before using information found on a webpage, consider the following criteria to evaluate its credibility:
Search Google for your topic keywords. Look for government, education, and/or organization webpages as well as news/magazine publications. Be cautious if using Wikipedia as the content cannot be verified. If researching controversial topics, be aware of biased publications.
If you're searching for information about creating digital media such as flyers and brochures, organizations that discuss graphic design (such as magazines and professional organizations) are good places to start. You can also search for social media marketing and online marketing.
You can use the templates on these websites to create flyers, posters, websites, and more.
