800 followers stuck is almost always a distribution problem, not a
content problem — you're posting into a void. X-specific mechanics, in
priority order:

THE ALGORITHM REALITY
X weights REPLIES and reshares far above likes, and it shows your post to
a small test audience first — if that group engages, it expands reach. So
early replies on your own posts matter more than the post itself. That
one fact reorders everything below.

WHERE GROWTH ACTUALLY COMES FROM AT YOUR SIZE
Not your posts — your REPLIES. At 800 followers your posts reach 800
people. A sharp reply under a 50K account reaches 50K. Reply strategy is
the growth engine under ~5K followers; original posts are for the people
that reply brings.

  The move: 5–10 thoughtful replies/day to accounts one tier above you,
  where you add something, not "great post 🔥." A reply that stands
  alone as a thought gets profile clicks; agreement gets ignored.

THREAD ENGINEERING
When you do post long-form, thread it. First tweet is a standalone hook —
it's the only part most people see, and it's what the algorithm tests.
The thread pays off the hook; the last tweet has the CTA. A thread whose
first tweet needs the second to make sense dies in the test audience.

PROFILE OPTIMIZATION — the conversion step
Reply strategy drives profile clicks; the profile converts them to
follows. Bio must say who you help and why to follow in one line. A great
reply that lands on a vague profile loses the follow.

COMPETITIVE INTEL
Find 5 accounts one tier up in your niche, study what of THEIRS gets
replies (via search), and enter those conversations early. You're not
copying content — you're finding the rooms where your audience already
is.

THE WEEKLY LOOP
Post daily, reply 5–10×/day up-tier, thread your best idea weekly,
check which replies drove profile clicks, do more of that.

What's the niche? That decides which 5 up-tier accounts to target first.
