Ad assets

Ad assets make your ad bigger and push other results down.

Sitelinks, callouts and structured snippets, once called ad extensions, add lines under your ad. Results that take more of the screen get looked at and clicked more (Lewandowski, 2017), and most clicks happen before anyone scrolls (Nielsen Norman Group).

Google shows an asset only when it predicts the asset will help, so add more than you need. Try yours in the mockup generator above.

How Google mixes your lines

Unpinned, one ad has 50,235 versions. Pin a few lines to take control.

Give Google 15 headlines and 4 descriptions in a responsive search ad, pin nothing, and it can build 50,235 different ads. Google predicts which to show instead of testing them all. But on the few thousand searches a month a B2B SaaS ad group gets, your proof and your call to action can wait a long time for their turn.

Google still mixes the lines inside each position, so it keeps testing. But every version it builds reads in order: their search, your proof, the next step. That is 18 headline orders to learn from, not thousands.

01

Pin by job, not by line

Pin two to four headlines per position. One per spot freezes the ad. None lets Google pair lines that repeat.

Ads with some lines pinned had the best cost per conversion, ROAS and CPC. Optmyzr, 1M+ ads

02

Fewer clicks, better buyers

Pinning lowers click-through rate a little. In return, more of the people who click go on to sign up.

More pinning, lower CTR, higher conversion rate and conversions per impression. Adalysis, 5,900 accounts

03

Ignore the push to Excellent

Google rates a pinned ad lower on Ad strength, but Ad strength doesn't decide your auctions. Average is fine.

Ads rated Average had the best cost per conversion, conversion rate and ROAS. Optmyzr, 1M+ ads

Selling B2B SaaS? Skip the blank headline boxes.

A mockup shows how your ad looks. It can't tell you what makes your buyers click. Start from an ad written about your product, and launch it without being a PPC person.

FAQ

Questions before you make a mockup.

Is the mockup generator really free?

Yes. There is no sign up, no limit and nothing to install. Type your lines, check the ad on desktop and mobile, and download it as a PNG.

Do you see or keep my ad copy and images?

No. The tool runs in your browser, and your images never leave it. A share link carries your text inside the link itself, after the # sign, which browsers never send to a server. Images are not part of the link, so whoever opens it adds their own.

Will Google show my ad exactly like this?

Close, not exact. Google picks which headlines and descriptions to show for each search and changes its layout by device and placement. Use Show another version to check how your lines read in different orders, and keep every line within its limit.

Can I send the mockup to my CEO or a client?

Yes. Download PNG saves the preview as an image for a deck or an email. Share preview copies a link that opens this page with your text already in place, so they can click through the other versions themselves.

I sell B2B SaaS. Can Hero Marketer write and launch the ad for me?

Yes. Give Hero AI the search you want to show up for and your landing page. You get keywords with what they would cost a month, and an ad written about your product, not a template. You check it in a preview like this one, then launch the campaign in your Google Ads account. Signing up and connecting your account are free. Ad copy uses about 0.2 credits and keyword research about 0.1. Credits come in $20 packs with no monthly fee, and unused credits are refundable within 90 days of purchase.
