There are two places reserved for Top Ad at the top of adsme.lk. If your ad is posted in the top ad, it will appear to the audience at the top more times.
This will appear in yellow to increase the amount of viewers to see than a regular ad. A top ad is valid for 15 days, and your ad gets thousands of extra views in those 15 days.
Bump ad is where your ad will be placed at the top of the listing. Every day, your ad will show up above the regular ads.
This helps to keep your ads above the other ads on adsme.lk every day without any extra cost or effort. This is repeated for up to 15 days.
