Adjust tone to match your employer brand voice
Google Policies to keep in mind
Capitalisation
All caps (e.g. FREE JOBS NOW)

Non-standard capitalisation unless it's a recognised brand name, trademark, or common abbreviation (e.g. ASAP, coupon codes)
Punctuation & symbols
Repeated punctuation (e.g. Amazing jobs!!! or Best offer???)
Symbols used to alter spelling (e.g. fl@wers, f1owers)
Symbols used for emphasis instead of meaning (e.g. **Amazing**)
Emojis & special characters
Emojis are explicitly prohibited
Single-byte katakana
Any invalid or unsupported characters
Repetition & spacing
Gimmicky repetition of words or phrases
Reusing identical text across multiple headlines or descriptions in the same ad
Extra spaces or omitted spaces between words
Style & grammar
Incorrect spelling or grammar
Incomprehensible or nonsensical text
Phone numbers in ad text
Promotional language in the business name field
Trademarks
Using third-party trademarks without authorisation
Non-standard trademarked spellings require a review request and must appear consistently on the destination website
⚠️ Any violation of the above Google policies will lead to ad rejection in the channel.
Size warnings and upscaling
Images
If an uploaded image is below the minimum dimensions for a placement, NEXT will attempt to automatically upscale it to meet the requirement. Upscaling is applied within quality limits to avoid visible degradation.
If upscaling succeeds, the rendition is marked Valid and the campaign can proceed.
If the image is too small to upscale within acceptable quality limits, the rendition is marked Invalid with a clear explanation. You will need to upload a higher-resolution version.
Each rendition in the Asset Library shows one of three statuses: Valid, Warning, or Invalid. A warning means the asset will work but may not display at optimal quality.
Any images with upscaling above 2x, will be rejected in the channels.
Logos
If your logo is below the minimum dimensions for its shape, NEXT will show a "Resize for me" button. Clicking it upscales the logo in-browser to meet the minimum requirement and proceeds with the upload automatically.
If the logo format is unsupported (e.g. SVG), an inline error is shown immediately on upload and the file is rejected.
Upscaling Examples
Common sizes that would be rejected on Meta:
Size | Reason |
800×800 px | 9:16: 1920/800 = 2.4× |
1080×1080 px | 9:16: 1920/1080 = 1.78× → actually not rejected (warning only) |
1200×628 px | 9:16: 1920/628 = 3.06× |
1200×800 px | 9:16: 1920/800 = 2.4× |
600×600 px | 9:16: 1920/600 = 3.2× |
1920×1080 px | 9:16: 1920/1080 = 1.78× → actually not rejected (warning only) |
