Rankings fluctuations can be panic-inducing, but they happen to everyone. Many of you who monitor your rankings in Google might do so weekly or daily or monthly.
Rankings drops and fluctuations are a part of life now that you’ve got a website. If you’re looking to rank for a specific keyword, they’re going to happen to you at some point, and they’re not usually a cause for alarm.
What should you do about this?
1. Do not freak out. A lot of people just lose their cool with their SEOs or with their team or with themselves.
2. I would recommend you to use weeks as your period, not days, and measure at least four to six weeks of rankings before you start to freak out over, "Hey, there's too much rankings fluctuation."
3. You should also compare your fluctuation to your competitors. So if you see, hey, I'm ranking here and I'm fluctuating a bunch, oh, but it turns the positions around me are also fluctuating, guess what? It's not you. It's the SERP. It's Google. Don't blame yourself for this.
4. I would try and compare your rankings to traffic. So it can be the case that if you're hitting your rankings on a particular day or from a personalized device or a geographic area or something like that, that you could be getting different kinds of rankings than what's being seen by most people.
5. The thing to be concerned about is steep falls over many pages in a quick period. So if you see that you've got 20 pages on your site, 50 pages on your site, they all lost rankings yesterday and fairly significantly, okay, that's cause for real concern.
