Now, I know we technically have a few days left in 2017, but I'm ready to dive head-first into a fond, full-blown retrospective. Each year we look back on what we've published, compiling and sharing the pieces you liked best. Normally we divvy it up via various metrics: traffic, 1Metric score, total thumbs up, total comments, the best of YouMoz, and so on and so forth. This year, however, we're doing things just a little differently.



A lot has changed in the past year...

The way we run the blog has changed in a few significant ways from the days of yesteryear. YouMoz, our user-generated content blog, was retired in the autumn of 2016 (though we hope to resurrect it in another form someday). We reduced our publishing frequency a bit, and refocused our content on core SEO topics after spending 2015 and 2016 branching out into other marketing subjects (like social media and content marketing). We also made some big changes with regards to commenting: we closed comments on posts older than 30 days (they became veritable spam factories), and implemented stricter moderation filters to better catch spammy comments fishing for either a link or easy MozPoints.

And if I'm being completely honest, I don't think the "Best of" posts from years past have offered you, our beloved readers, as much value as they should've. The most excited comments on those posts occur when someone discovers a gem they'd missed, when a post reaches out to you from the masses of online content clamoring for your attention and speaks to you. The way we formerly ranked "the best" resulted in a lot of overlap; the same few posts with lots of thumbs up, a busy comments section, and high traffic overwhelmed the leaderboard.

What criteria now determines "best"?

At the end of 2017, we're starting fresh. First, I've taken our ten most popular blog post categories by traffic — these represent the topics readers are actively seeking information on. Next, I thought about which metric matters most to me when I consider the success of a blog post. Traffic, thumbs, social shares... Nice to see, yes, but they don't paint a very clear picture of a post's impact. I found myself returning to my favorite blog post metric again and again: the comments.

A post with a lively comments section can be many things. Perhaps it sparked questions or debate; perhaps the findings were controversial; perhaps it was simply inspiring. Whatever the reason, a heavily commented-on post represents something that struck a chord, that convinced a person to peek out from behind their keyboard shield and contribute a thought, something that coaxed a little extra effort and commitment from our community. As a silent lurker myself, I am consistently blown away by the humility, genius, and generosity you all display in the blog comments section every day.

So there we have it: this year's Best of the Moz Blog 2017 is a list of the top five most-commented posts in the top ten blog categories. That's fifty unique blog posts throughout the year on a variety of topics, some of which you may have missed. Most blog posts fall into several of our categories, but every post will only be listed once; if it's hit the top five in a more popular category, I've taken it out of the running for the rest. It's my sincere hope that this list uncovers something useful for you, something that helps make your job and day just a little easier.

Without further ado, let's get this party started!

(If you're curious, check out the Best of 2016 and the Best of 2015, too.)

The top 5 Whiteboard Fridays

Whiteboard Friday is far and away our most popular blog category, earning three times as much traffic as the rest. Because it always overlaps with at least one other category, you're bound to get a tidy grab bag of SEO takeaways with this list!

The top 5 posts in On-Page SEO

The results of our recent Moz Blog Reader Survey highlighted on-page SEO as the topic you'd most like to learn about, so it's not surprising to see that this category sits right under Whiteboard Friday for popularity. There's an interesting theme that emerges from these top posts: it seems we're still working on many of the same things, but how we treat them has necessarily changed over time.
