Image SEO: Optimizing Photos for Google Search and Local Discovery

For industries with high visual appeal—such as builders, landscapers, wedding cake designers, florists, and interior renovators—Google Images is a primary discovery engine. Prospective clients frequently search visual terms like 'modern cedar deck Palmerston North' or 'custom celebration cakes Manawatū to gather inspiration before making an inquiry.

Without proper image optimization, your photography remains invisible to search engines and acts as a performance bottleneck that slows down your website.

Search crawlers inspect the file name before reading the surrounding page copy:

• Bad File Name: IMG_49201.jpg or screenshot_2026-09-12.png (Zero algorithmic value)
• Good File Name: residential-heat-pump-installation-palmerston-north.webp

Always use lowercase letters separated by hyphens. Include your core service and geographic location where relevant, without engaging in keyword stuffing.

The alt attribute serves two critical functions: screen reader accessibility for visually impaired users, and indexing context for search bots.

Follow these guidelines when authoring alt text:

• Be Accurately Descriptive: Describe the subject and action taking place.
• Include Natural Context: 'Qualified electrician wiring an upgraded switchboard for a residential renovation in Hokowhitu, Palmerston North.'
• Avoid Keyword Stuffing: Never write 'Electrician Palmerston North best cheap electrical repair'.

Serving uncompressed 4MB JPEG or PNG images directly from a camera destroys mobile performance on New Zealand 4G/5G networks.

Aim to keep hero images under 150KB and standard body photography under 70KB.
