google search console showing drop in keywords ranking

Hello guys,

I have been creating backlinks slowly using tools, all links are web 2.0 contextual links. I have been building links from the past 6 months. I was ranking for 116 keywords if I see 6 months overview in my search console. From past 3 months I am seeing decline in my sites impression on google serp and number of keywords i was ranking for is decreasing as well. I want to know what could be the issue here? Is my site under sandbox? OR is it something else? I had been using indexers and drip feeding links as well. Not a whole lot of my links are indexed yet in google serp, as i have not been indexing links like crazy. Any inputs are appreciated.

Thanks

Add fresh content and build different links not just Web 2.0 it’ll come out

Not overusing the same anchors? You have plenty of diversity here?

These kind of links might have given a little boost to the website in the beginning, but not anymore. Keep in mind there's no sandbox effect.

The reason for your ranking drops is that these kind of links won't rank your keywords.
