How a description works
A description is the block of ad text that sits under the headlines. In Google Ads it is limited to ninety characters including spaces, and you supply several per responsive search ad rather than writing one final version. Google then chooses which to show, usually one or two, and the choice varies with the search, the device and the space available.
Unlike a headline, a description is not guaranteed screen time at all. On a crowded results page, on a small screen, or in certain layouts, a second description may not appear and the text may be cut. Anything that has to be read must therefore sit near the front of the line, not saved for the end.
Why descriptions matter
The headline earns attention; the description earns the click from people who are nearly persuaded and have one thing left to check. That is usually a practical question: do you cover my area, do you handle my situation, how quickly can you start, what does it cost to find out. Answering it in the ad converts a browser into a visitor.
It is also the cheapest place to filter out the wrong people. A description that names a minimum project size, a service area or a qualification you require will lose you some clicks, and those are clicks you were paying for and would never have converted. On a small budget, which is the normal situation for businesses advertising in Nepal, that filtering is often worth more than the extra traffic.
Common mistakes with descriptions
The most common is restating the headline in longer words. If the description adds no new information, the reader gets nothing for the second glance and the ad has used its space to repeat itself.
The second is saving the point for the end. Because the line can be trimmed and the second description may never run, a description that builds to its conclusion often loses the conclusion.
The third is filling ninety characters with adjectives. Professional, reliable, affordable and customer-focused are claims every competitor is also making, so they read as noise. A single concrete fact does more work than a full line of praise.
How to act on it
Write each description to answer one objection, and write it front to back: the answer first, the supporting detail after. Give each one a different objection so the pool covers a range of readers rather than one.
Include a plain instruction somewhere in the set — book a call, request a quote, check availability — phrased as an action rather than a slogan, and make sure the page behind the click lets the reader do exactly that. Check the length with the ad copy character counter before saving, since the limit is refused rather than trimmed. Then read the asset ratings once enough traffic has passed and replace the weakest lines instead of rewriting all of them.
