While using these search engines and meta-search engines I noticed the three most popular websites to come up was Wikipedia, WebMD, and APTA (American Physical Therapy Association). This is probably because these three websites give the most insight to the field of Physical Therapy. This shows that all search engines generally pull up the same important information for the most part. One difference I noticed was that google and yahoo pulled up a lot of results based on my location. The meta-search engine WebCrawler search results were by google and yahoo. I found that really interesting. It also explained why my results on there were a mix of both results I got before. Another difference I noticed was that every search engine and meta-search engine had ads at the top except google, which is at the bottom.
