Ad copy checker. Character limits that count Hebrew right.

Google responsive search ads take up to 15 headlines of 30 characters and up to 4 descriptions of 90 characters. Meta’s primary text has no hard limit, but in many placements text beyond about 125 characters is cut behind “See more”, so the tool warns rather than blocks there.

Headlines over the limit are flagged in red with how many characters to cut. The tool also flags an exclamation mark in a headline, which Google’s editorial policy doesn’t allow.

Characters are counted as grapheme clusters with the browser’s Intl.Segmenter: one count per character you see. A Hebrew letter with niqqud is one character on screen even though it’s stored as two or three code points.

When niqqud is present, the tool shows both counts, with and without the marks, because how each platform counts niqqud isn’t documented. If a line is close to the limit and uses niqqud, test it in the ad editor before you publish.

Hebrew ads often contain a brand, a product code or a number in Latin characters. The text input uses automatic direction, which follows the first strong character. A line that starts with an English word is laid out left-to-right, and punctuation at the edges can appear on the wrong side.

The checker marks lines that mix Hebrew and Latin, and warns specifically when a Hebrew line starts with a Latin word. The preview isolates each headline so you can see how it will read in an RTL results page.

The preview is a simplified search ad: the first three headlines joined by separators and the first two descriptions. Google assembles responsive ads in many combinations and may show fewer headlines, so the real ad can look different.
