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.

Solving Duplicate Content Issues with Http and Https

I just took a premium account with SEOMoz and saw the canonicalization video. It was impressive except the https part of it. It said that, for https try to redirect to http in case of bot and otherwise show the https page, as https pages are meant for users not for bot.

Does "Query Deserves Diversity" Algorithm Exist at Google?

Most of us in the search space are familiar with the principles of the "query deserves diversity" (QDF) algorithm at Google, but this is almost certainly not the only intent detection process and algo-tweaking area the engine applies.

Google Follows Nofollowed Links in SEOmoz Comments?

I may be totally wrong on this, or maybe I've overlooked some obvious explanation as to why the content on the end of nofollowed SEOmoz comment links has been indexed and ranked.

Did You Mean? - No, I Didn't

I'm sure we have all seen it, or have had it happen to us. You are doing a search on Google and you get a results page that says "Did you mean, ####" at the top of the page. I firmly believe that this is a helpful tool to many people who are either horrible spellers, or had a momentary "brain-fart"! But what do you do when this affects your own search engine traffic?...

Is Google Making Site Search Redundant?

So here's an interesting thought... You're Google. You have every page on everyone's site in the world (or near as makes no odds) indexed. What more can you do with that information?Well, how about providing a search function for that person's site. Looks like that's what the big G is thinking at the moment at any rate.
