Comments, saves and shares: the engagement worth paying for

Almost everybody buys likes, because likes are the cheapest line on the price list. Almost every platform weights them the least.

What the platforms actually weight

Ranking systems differ in detail but agree on the principle: the more effort an action takes, the more it counts.

1. Shares and sends — the strongest signal on most platforms. Sharing something is a public endorsement.
2. Saves and bookmarks — "I want this later" is close behind, and it is the signal Instagram leans on most heavily for Reels.
3. Comments — high value, especially where they generate replies.
4. Watch time and completion — the entire ranking on video-first platforms.
5. Likes — the cheapest action a person can take, and weighted accordingly.

Buying is usually the exact inverse of this list, which is why so much of it produces no visible effect.

Saves: the best value on the list

Saves are inexpensive, weighted heavily, and — critically — invisible to other users on most platforms. Nobody can look at your post and see that the saves were bought, because nobody can see the saves at all.

For a post you genuinely want distributed, saves are the single most efficient purchase available, and hardly anyone makes it.

Shares: high value, use sparingly

Shares carry the most weight and are semi-visible: on several platforms the share count is public. A post with 900 shares and 12 comments is a shape that does not occur naturally, so buy shares in a quantity that fits the rest of the post's numbers.

Comments: worth it only if they are custom

Generic comment services deliver "nice", "🔥🔥", "good post" — and a column of those under a post is read correctly by every human who scrolls past. It actively damages the impression you were paying to create.

Custom comment services let you supply the text, one per line, and you are charged per line. Written properly — specific to the post, varied in length, a couple of questions among them — they do the opposite: they invite genuine replies, and replies are engagement you did not pay for.

Write them as different people. Three sentences of similar length with the same punctuation is one person typing three times.

Likes: still useful, just not for ranking

Likes remain worth buying for one reason: nobody wants to be the first. A post with zero likes gets fewer real likes than the identical post with forty, and that is a genuine effect rather than an algorithmic one.

So buy them for the cold-start problem, in proportion, and stop expecting them to move distribution.

Proportion is the whole game

Whatever you buy, the numbers have to be plausible against each other. Rough guides on a typical small account:

• Likes: 2–8% of followers.
• Comments: 1–3% of likes.
• Saves: 5–20% of likes on genuinely useful content, far less on ordinary posts.
• Shares: usually below the comment count.

A post that breaks these badly reads as bought even when every individual number is modest.

Timing, again

Engagement arriving in the first hour influences whether the post gets shown further. The same engagement arriving on day three is decoration. If you are only going to get one thing right, get the timing right and spend less.

What to buy for one important post

A pattern that works better than a large like order:

1. A small number of saves, immediately.
2. Likes proportional to your follower count, over the first hour or two.
3. Three to five custom comments, written as different people, spread out.
4. A handful of shares only if the platform shows the count and the rest of the numbers support it.

That costs less than a large like order and does considerably more, because it matches what the ranking system is actually reading.

Writing custom comments that do not read as bought

If you are paying per line, the lines are worth thinking about. What gives them away is uniformity, so vary everything:

• Length. Two words, then a sentence, then a question. Real threads look ragged.
• Register. Some capitalised, some not. Some with an emoji, most without.
• Specificity. At least one comment should mention something only visible in the post — a colour, a price, the second item on the left.
• Questions. One or two, because they give you something to reply to and replies are the engagement you did not pay for.

Ten minutes writing these is the difference between a thread that invites participation and a thread that announces itself.

Where the engagement lands matters too

Spreading a small amount across your last four posts usually beats concentrating everything on one. A profile where every post has some engagement reads as an account with an audience; a profile with one post at 800 likes and eleven posts at four reads as one purchase.

The exception is a post you are actively promoting elsewhere — an ad, a link you are sharing — where concentration is the point.

Saves are the quiet one

Of everything on the list, saves are the signal most people ignore and the one Instagram appears to weight highest. A save says the viewer intends to come back — it is the closest thing the platform has to a statement of value, and it is invisible to everyone but you.

That invisibility is the advantage. Nobody can look at your post and count the saves, so there is no amount that looks suspicious to a human reader, and the effect on reach is real. If you are choosing one thing to spend on for a post you want to travel, this is it.

Shares sit just behind them for the same reason: a share is a viewer spending their own credibility on your post, which is the most expensive thing anyone can do with it. Both are worth several times a like at a price that is rarely several times higher.

The thing worth remembering

You are buying signals, and signals are read in context. A number that does not fit its neighbours is worse than no number at all — it tells a viewer exactly what happened, and it tells the platform that the engagement did not come from the audience the post was shown to.

No comments yet — be the first.
