I used to average around 800 uv daily but now am just getting about 600 uv daily. This is despite the fact that I am still as hard as before. Am I the only one noticing this?
I think you are not using good title on your posts now a days or may be you have changed your style to some extent..
That happens to many sites, sometimes you get boost in rankings and traffic sometimes it lowers due to Google Dance...
have you check your rankings.. it might declined, that might be the reason.. but yah that's usually normal..
It's a usual bounce.. got it many times.. One of my blog is doing around 1.2k raw daily now it's on 7-800 raw daily.. but it happened before, then it went up.
You can try a bit of promotion once again. I will revamp my site too because it lacks traffic unlike before. Speaking of Google, they say they are not even updating the page ranks yet.
This can be due to the below reason 1. your keyword drop on SERP 2. Less people search on the keyword
use all statics tools you can and define what work best for your visitors. after you understand exactly what's your site strength try do it more of it... adding links is good idea as well
Your fluctuate ratio is not that high. If your traffics were 800 then dropped to 100 then you should worry. However, it would better if you check for your long rail keywords / inner page ranking instead of just your main targeted keyword at homepage. You might find more clue about the dropped traffics.
