4.2. Google Basics

Simply stated, Google is the standout leader in search today. It has the most traffic and the most new trends, and it's the only search engine with its own entry in the dictionary. Once a search-only entity, Google now offers e-mail, maps, feed readers, calendar, web analytics, and webmaster tools, not to mention a diverse menu of specialty search options, including news, video, image, blog, and local. See Table 4.1 for handy Google facts for SEOs.

Google has been an all-out trendsetter in the evolution of the search space. Link popularity? Google made it hugely important. Integration of specialty search results within standard results? Thank Google. A website's age being a factor in its ranking? Blame Google. We'll go into the details throughout the book, but let's face it: The world of SEO is playing Follow the Leader, and Google's at the head of the line.

Google Analytics, the free and robust website traffic analysis tool, has been widely adopted since its launch in 2005. This was arguably the single most important development in SEO in recent years, because it gave the world's website owners the ability to easily measure conversions. This has precipitated a shift in the collective SEO mind-set to valuing conversions, not ranks, as the most important metric.

The current hot topics around Google are its mission expansions: From TV to voicemail to the supermarket aisles, the big G is everywhere. Ambitious lately? Staying on top of the long, and ever-lengthening, list of services Google offers can be overwhelming for a website owner. But you don't need to, as long as you focus on the services your target audience cares about. Most people are still using Google at its most basic level, typing a phrase in the search box, and seeing what results come up.

Google's current relationship with SEOs and webmasters has its points of light along with some black holes. SEOs appreciate the monitoring and management options available through the Webmaster Tools service and outreach by corporate representatives via blogs, forums, and conferences, but many SEOs kvetch about Google becoming too powerful. One topic that really brings out the bristle is Google's announcement in 2007 that paid links (inbound links that are purchased in an attempt to improve search engine ranks) should be reported to Google, presumably so that Google can mete out negative consequences. Besides feeling that the web community shouldn't become snitches, many people consider this preferential ("Why aren't Yahoo! Directory links considered paid links?") or illogical ("Isn't there payment of some sort—labor or money or favors—involved in all web marketing efforts?").

Even as you gobble up the free tools, services, and advice from Google, remember that there's no such thing as a free lunch. Google is a for-profit company, and an incredibly powerful one at that. Google will look after Google and, in doing so, may make policy changes that can create seismic shifts in website owners' lives. It's always best to create your site for your users, not for what you think will cause Google to rank you higher this week.

PageRank, ShmageRank

Google's PageRank is a measurement of a page's worth based on the quantity and quality of both incoming and outgoing links. The concept behind PageRank is that each link to a page constitutes a vote, and Google has a sophisticated and automated way of tallying these votes, which includes looking at a vast universe of interlinking pages. Google awards PageRank on a scale of 0 to 10; a PageRank value of 10 is the most desirable and extremely rare. Like the Richter scale, the Page-Rank scale is not linear, so the difference between 4 and 5 is much greater than the difference between 3 and 4.

More often than not, pages with high PageRank have higher Google rankings than pages with low PageRank. And therein lies the link obsession. Throughout the SEO community, the scrambling for, trading, and even selling of links became such a focus over the past several years that Google modified its system and began to devalue certain kinds of links. It's widely accepted, for example, that links from content-deficient "link farm" websites do not improve a page's PageRank, and getting a link from a page with high PageRank but irrelevant content (say, a popular comic book site that links to a forklift specifications page) won't either. Google now displays updated PageRank values at infrequent intervals to discourage constant monitoring.

It's good to get links to your site, but obsessive link building to the point of excluding other areas of SEO is a waste of time. Keep a holistic head on your shoulders and remember these points:

  • Google's ranking algorithm is not based entirely on inbound links.

  • A high PageRank does not guarantee a high Google rank.

  • A PageRank value viewed today may be months old.

PageRank is still a fairly good indication of how Google regards your website's pages, and you'll learn how to gather your own measurements in Your SEO Plan. But in the Right Now of SEO, think of PageRank as a hobby, not a religion.
