In his blog, Mike Grehan discusses his view of search engine optimization (SEO) and how sites out there break the guidelines of search engines. Grehan opens his discussion by questioning whether or not it is unethical for people to break the guidelines despite the fact that the pages are completely relevant to the search queries. It’s obvious that a site breaking the guidelines generate a lot of spam due to its desire to increase its PageRank. Grehan compares this type of spam to email spam. He claims that among the increased spam emails that people receives, some of these might actually be of interest. Relating to webpages, if a page is relevant, then the issue of breaking guidelines should be of no matter to the end user (searcher). However, he raises the issue that there’s a possibility that people might not trust search results if too many webpages have broken the guidelines to get their page to the top. According to Grehan’s research, people have less trust in email due to spam.

I agree with Grehan’s overall perspective because the normal person would not realize that companies and organizations do everything to give their pages the highest PageRank. As end users, we need to learn how to recognize unethical tactics employed by some websites so that we can trust the genuine ones that are relevant to our searches. Like what Grehan said, if one day, all we get from search engines are spam, then search engines would slowly die out. So it is important that no one should break the guidelines even though links may be relevant to search queries because there is the same chance that these links are spam.
