Search Engine Optimization (SEO)
An important aspect of search engine optimization (SEO) is making your website easy for both users and search engine robots to understand. Although search engines have become increasingly sophisticated, they still can’t see and understand a web page the same way a human can. SEO helps the engines figure out what each page is about, and how it may be useful for users.
A Common Argument Against SEO
We frequently hear statements like this:
“No smart engineer would ever build a search engine that requires websites to follow certain rules or principles in order to be ranked or indexed. Anyone with half a brain would want a system that can crawl through any architecture, parse any amount of complex or imperfect code, and still find a way to return the most relevant results, not the ones that have been ‘optimized’ by unlicensed search marketing experts.”
But Wait …
Imagine you posted online a picture of your family dog. A human might describe it as “a black, medium-sized dog, looks like a Lab, playing fetch in the park.” On the other hand, the best search engine in the world would struggle to understand the photo at anywhere near that level of sophistication. How do you make a search engine understand a photograph? Fortunately, SEO allows webmasters to provide clues that the engines can use to understand content. In fact, adding proper structure to your content is essential to SEO.
Understanding both the abilities and limitations of search engines allows you to properly build, format, and annotate your web content in a way that search engines can digest. Without SEO, a website can be invisible to search engines.
The Limits of Search Engine Technology
The major search engines all operate on the same principles, as explained in Chapter 1. Automated search bots crawl the web, follow links, and index content in massive databases. They accomplish this with dazzling artificial intelligence, but modern search technology is not all-powerful. There are numerous technical limitations that cause significant problems in both inclusion and rankings.
