Accurately measuring results is one of the greatest opportunities that we have access to through online marketing. Analyzing and evaluating these measurements allows us to observe which practices yield the best results. We can organize these results into lists as a visual way of representing the resources that are performing the greatest for various topics. This leads to many websites in the online marketing industry producing “Best of Lists” throughout each year.

So in that spirit we’ve put together a list of the 50 “Best Of” lists covering the online marketing space. Note: The rankings are simply divided by categories, not in order of importance. We are using the numbers solely to prove that we did, in fact, get to 50.

Online Marketing

1. Forbes kicks off our list with their Top 10 Online Marketing Experts To Follow In 2014. The individuals on the list specialize in different subject matter from varying backgrounds. But each of them are all a wealth of knowledge when it comes to online marketing.

2. One thing that online marketing and blogs have in common is that they need to contain good content. Good content comes from great writing. Writtent.com knows all about that and has compiled a list of The Top 25 Must-Read Internet Marketing Blogs.

3. Gyutae Park’s Winning the Web website uses Alexa, PageRank, Technorati, and Feedburner among other metrics to measure its Internet Marketing Top Blogs. Total number: 370.

4 . Radius – a company that designed predictive and intuitive software to help companies re-imagine growth decisions – has compiled a list of The Best Marketing Blogs of 2015. What we like about this list is that the sites that made the cut were voted upon by readers, and therefore, people who are actually benefitting from utilizing these sources.

5. Kaiser The Sage’s (AKA marketing consultant Jason Acidre) has produced his Top 90 Online Marketing Blogs. He has provided a dense, but diverse list of blogs who hold the top authority in each of their specialties. There is even a section dedicated to some up-and-coming blogs to keep an eye out for.

6. Practical Ecommerce is a site that provides a lot of useful resources for online merchants. Here they have compiled a guide to 12 Useful Ecommerce Blogs.

9. The team at Branded3 say a good deal of blog ranking tables created recently use the hugely inaccurate and outdated Google PageRank as a method of measuring success. Their solution? A table that uses Alexa Rank and Technorati Rank to calculate the popularity of each site. The result is a list of the Top 100 SEO & Internet Marketing Blogs.

10. HubSpot created the Hot 100 Marketing Blogs list in order to make it easy for people to discover top digital marketing blogs. Hubspot has said, “We’re continually collecting 3rd party data for several thousand blogs that cover Internet marketing topics.” This certainly shows with the strength of the list they’ve put together.

11. The Top 20 Digital Marketing Blogs from Sparxoo. The first five below:

Forbes.com pulls together a great pictorial of the Best-Ever! Social Media Campaigns. Spoiler alert: The Blair Witch Project comes in at #1. Pretty impressive considering it was among the first social media efforts way back in the day (1999).

20. Not to be outdone, social marketing and media blog The Wall decided to go the distance with 40 more and release the Top 50 Social Media Campaigns. Oddly enough, The Blair Witch Project doesn’t even crack the top 50. Guess these lists are a bit subjective. Plus, with these guys being British and all they may have missed that buzz way back when.

21. Of course, you can’t even say social media these days without wondering what Marc Zuckerburg is doing for lunch. Social Media Examiner apparently also has the Zuck-bug and decided to create a 10 Top Facebook Pages post. Number 1? Red Bull. Apparently they’re in tune with their audience.

22. In the case of Smart Blog, the best means the worst. Rachel Crandall put together the best “Worst Of” list compiling 4 Twitter Campaigns That Went Horribly Wrong. Top of the list?
