Organic traffic always stuck

anyone has this problem?

I been monitor for some weeks, noticed the highest organic traffic is like
only reach certain numbers that it cannot increase any more over
for an example

let's say the max organic traffic per day is 300 , some days will be less 200 or maybe 100
than back to days increase back but at most reach 300

is seem can't over 300.

is due to your keywords because is limited? or?

Are you publishing new content which should bring more traffic?If not then It's normal to see no increase in traffic. Another reason would be no ranking changes on SERP.

Publish Some good content, find keywords in your niche that has good traffic and post content according to that keyword
When they will start ranking you will more traffic

Also look for similar keywords related to your current ranking keyword which are giving you traffic.
Change your content according to those keywords too
It will help you better in getting traffic that you desire

Content is king also ranking number 1 for a keyword with low search volume wont produce much results

How about back links side
It should helps too isn’t
