Google rolls out algorithm updates once or twice every month (and that's just the ones we know about!), but not all of them have an equally strong impact on the SERPs. To help you make sense of Google's major algo changes in the past years, I've put up an up-to-date cheat sheet with the most important updates and penalties rolled out in the recent years.
Starting with Google's Pigeon update back in 2014, local SEO has been getting more and more like general, non-local SEO. About a year ago, Possum seemed to make things even trickier with different SERPs returned in response to teeny-tiny variations in search queries. By looking at several studies, I tried to put together the factors that are most important for local rankings in Google. Some of those were… unexpected to say the least.
As Google's search results grow increasingly personalized, accurate rank tracking is becoming a challenge. The concept of accuracy itself has become somewhat vague: if there are as many SERP variations as there are locations, which one should you consider "accurate"? In this post, I'll look at the different ways Google personalizes search results, their impact on SEO, and tips to ensure that personalization doesn't falsify your ranking data.
Google's results can be misleading, biased, or just wrong — and when we spot the obvious blunders, we tend to laugh them off. "That's alright, computers make mistakes". But what about the information that we don't know is incorrect or incomplete? And what about deliberate wrongness? Let's look into Google's search quality crisis, the possible reasons behind it, and the implications it has for how we form opinions about the world.
Paid link building isn't something a lot of SEOs are willing to openly talk about — not if they do it, anyway. Perhaps that's what makes it a tactic that's mysteriously attractive and so freakin' dangerous at the same time. For this post, I spoke to 10 professional SEOs, asking them for their honest (and anonymous) opinion on paid link building.
