What ad quality measures
Ad quality is Meta’s judgement of the experience your ad gives the person who sees it. It is assembled from several kinds of signal. Some come directly from users: hiding the ad, reporting it, choosing not to see it again, or the opposite — watching, saving, commenting genuinely. Some come from the ad itself, particularly tactics Meta treats as negative, such as asking for likes, shares or tags in order to inflate engagement, sensational or withheld information, and images designed to mislead about what is being sold.
The rest comes from what happens after the click. A page that loads slowly, does not match the ad, buries the offer under interstitials or carries little real content all count against the ad, even though they sit on your website rather than in Ads Manager.
Why ad quality matters
It is one of the three inputs into total value, the score that decides who wins each auction. Poor quality means you need a higher bid to win the same placement, so a quality problem arrives on your invoice as a cost problem. Advertisers usually notice it as a rising cost per thousand impressions with nothing in the settings having changed.
In markets where most people are on mid-range phones and variable mobile data — Nepal very much included — the post-click half of this deserves more attention than it usually gets. A heavy landing page loses people before it loads, and Meta sees that as a poor experience it delivered.
Common mistakes with ad quality
The first is chasing engagement with bait. “Comment YES below” and “tag a friend who needs this” do lift the visible numbers, and they are precisely the behaviours the quality signals were built to catch.
The second is optimising the ad and ignoring the destination, so a good creative sends people to a slow page that answers a different question. The third is misreading the diagnostics: quality ranking is relative to other ads competing for the same audience, so a below average label means competitors are doing better with these people, not that your ad is broken. And it appears only once an ad has gathered enough impressions to compare.
How to act on it
Start with the truthfulness of the ad. If the creative promises something the page does not deliver, everything downstream suffers and no amount of bidding fixes it. Then check the page on a real phone on a real connection rather than on office wifi, and cut whatever is slowing it down.
Refresh creative before people tire of it, because a tired ad earns more negative feedback than a new one saying the same thing. Watch the quality, engagement rate and conversion rate rankings together, since they separate a weak creative from a weak destination. And drop the bait entirely: the short-term engagement it buys is paid back with interest in delivery costs and, at worst, in policy restrictions on the account.
