Understanding how search engines work, Google in particular, is important when working in SEO. The basics of crawling and indexing are amazingly useful to understand if you want to rank your own content.
Additionally, Google updates its algorithm several times a year. Understanding the more significant updates, and how they work, can help you to craft content and SEO strategies that are up-to-date.
We've written extensively about how search engines work, and included some of the top resources here. You can also browse the latest posts on search engines from the Moz blog below.

Google's head of web spam (a division of the engine's search quality division) recently posted a piece entitled, Why Google Won't Remove that Page You Don't Like. An excerpt: Every few weeks or so, someone contacts me and says “Hey Matt, there’s page out on ...
My coworker Mike and I were pondering lunch options today and decided to order from the Honey Hole, one of Seattle's best sandwich places. Every day the place has a line out the door because it's a popular haven for hungry Seattleites who want a belly full of sandwichy goodness, so sometimes we elect to call our order in and pick it up.
I was pinging people on Twitter about what to blog about, and Michael Vandemar suggested I take a look at his post about Google web search switching to AJAX. He and some other SEOs have recently noticed that Google search results URLs have been displaying the search query string after a ha...
Thousands of posts, news articles and analysis pieces have covered the central topic of battling Google's dominance in web search, but I've seen very few that have discussed what is, in my opinion, the most telling example of the search giant's dominance. The latest (made popular across Techmeme and many individual blogs) was this piece from C|Net's Don Reisinger:

With every tweak and change that Google brings to its search result pages, the "potential-ROI" balance on search tips ever more towards PPC and away from SEO. I realized this when I read Aaron Wall's Marketing Lessons from Google. Search marketing leaders demand results, so it's irrelevant that the means of practicing SEO remain the same. What is relevant is that Google is decreasing the ability of SEO to provide stable, measurable results. As Aaron points out in his post, Google seeks to undermine competing business models.
When search marketers get together at a pub and talk, the conversation inevitably turns to Google's near-monopolistic share of web search. For many of us that are new to the field, Google has always been the market leader and the focus of most of our efforts. But historically, this wasn't the case. Have a look from a historical perspective: ...
As I was stumbling around the web today, building some slides out for my Pubcon sessions next week, I came across some search results I couldn't help but blog about. Have a peek: ...
One of the central goals of all the major search engines has always been to limit the extent to which manipulative activity could affect the top search results. It's been my general opinion that there's no better place to start this enforcement than our field - search engine optimization - and the SEO companies that offer this service. It was therefore to my dismay to see the following search r...
There's been some talk in the past year of Google results appearing to be case sensitive. The phenomena appeared first in the UK and as of late in US as well. No, I'm not talking about crop circles. I'm surprised that much of this has been brushed off as datacenters or, perhaps, the anchor text of inbound links, as was smartly suggested in a recent Q+A here on the 'moz.
After watching Nate Buggia a few weeks ago speak about Live's Webmaster Tools I was struck by his statistic about the number of domains on the web. He suggested that there are 78 million domains. Could we manually review all of them?
What's the deal with all this advice that Google employees like to give us, then? Of all the search engines (and of many companies of Google's size and scope), Google appears to be the most open with its distribution of information, its interactions with its users and its willingness to give us advice.
Sometimes you come across a set of search results that just don't make any sense. For most ordinary users, I suspect they probably just move on to the next query, but for those of us deeply embedded in the world of search and SEO, these noggin'-scratchers just keep on itchin'. I've collected these ten over the past couple months and figured I'd share them on the blog with the hopes of g...
This guide came around as the result of a post I previously wrote for YOUmoz, which in itself came around as a result of a night of drinking and being sent an interesting Google SERP. That post focused on the URL parameters you can feed into Google to generate SERPs.This time however I’m looking at Google Maps....
I must have missed something. I always thought Google doesn't see links inside JavaScript code. As Rand writes in the Beginner's Guide, JavaScript passes no ranking or spidering value and pages behind JavaScript navigation may never be found by search engines if they are not reachable v...
