I have noticed for a long time (but have never asked about it) that we have many keywords that we will rank fine for, but then one week they are not ranked at all and the following week they will be back to around the original ranking. It seems to be a different set of words that this happens to on a weekly basis. Is this normal or is it an indicator that there is something amiss with our site?
Thanks for your insight. I hope you are doing well!
Yes, that's normal because rankings always vary for a thousand different reasons. In this case, you're likely just seeing results from different databases.
This is why you really shouldn't be measuring rankings anyway, because they're potentially different for every user, browser, computer, etc. See my article on why rankings are a poor measure of success.
(You should also note that if you're checking rankings in some automated fashion and Google finds out, they may very well implement a penalty on the site.)
Do you find your site traffic for those keywords to vary as well? That's what I would want to look at by using analytics to measure your success.
Hope this helps!
