Image SEO for Financial Advisors: Alt Text, File Names, and Size
Here is an image problem most site owners have never thought about. Photos go up straight from a phone or a stock library, still called IMG_4729.jpg, with no alt text, at two megabytes apiece. Spread that across a homepage, three service pages, an About page, and a dozen posts, and it adds up fast.
Image SEO is some of the easiest work on an advisor site. It is mechanical, the signals are real, and the speed you gain tends to help everything else on the page. This post covers the three image problems I keep finding, what to do about each, and where AI search engines come into it.
Why images matter for advisor SEO
The obvious one
Image search
The big one
Page speed
The newer one
AI search
Three ways images affect how a firm is found.
Image search. Some searches for a phrase like "fee-only financial advisor Nashville" surface image results. A headshot with a sensible file name and alt text can appear there.
Page speed. Unoptimized images are the biggest cause of slow advisor sites that I see. Speed is a confirmed ranking factor, and on most of these sites the quickest way to improve it is to compress and resize the images.
AI search. When ChatGPT, Claude, Perplexity, or Google's AI Overviews put together an answer, the text around and attached to an image is part of what they can read. Properly labeled images give them more to go on about what the firm does and who it serves.
For most advisor sites, speed alone justifies the time.
The three image problems advisor sites have
Problem 1: Generic file names
IMG_2843.jpg, DSC_0091.JPG, and shutterstock-stock-photo-4928374.png tell Google nothing. The file name is the first thing a search engine reads about an image.
Problem 2: Missing or useless alt text
Alt text describes the image for people using screen readers and gives search engines context. Sites either skip it or put the firm name on every image, which helps nobody.
Problem 3: Huge files
A modern phone produces images 3,000 to 5,000 pixels wide and several megabytes in size. Squarespace will display them, and mobile visitors on slow connections pay for it.
File names that help Google understand the page
Rename before you upload. A good file name is short, descriptive, hyphenated, and lowercase.
Bad

Tells Google nothing.
Better

Best

Name, credential, city, and role.
One photo, three file names. The last is still under the 60-character guide.
The third version belongs on the About page where that photo lives. It says the photo shows the firm's founder, his credential, his city, and his role.
- Hyphens between words. No spaces, and no _ characters.
- Under 60 characters or so.
- Describe what is in the image, not which page it is on.
- All lowercase.
- No filler words like "image" or "photo."
It takes about 30 seconds an image.
Alt text rules for advisor sites
Write alt text for someone who cannot see the image. Search engines read it the same way.
Good alt text

Alt text examples from this section.
- Describe what is in the image, not the page it sits on.
- Keep it under about 125 characters, because screen readers tend to cut off after that.
- Do not stuff it. "Nashville financial advisor fiduciary fee-only CFP retirement planning" is worse than a clean description a person would say.
- For decorative images such as background patterns and divider lines, leave alt="" so screen readers skip them.
On a typical advisor site, fixing alt text everywhere is an hour or two.
Image size and compression for Squarespace
This is where the speed comes from. Squarespace serves responsive sizes automatically, but only up to the dimensions of what you uploaded. Give it a 5,000-pixel image and it will send something close to that to large screens.
| Image type | Upload width | Format | Target file size |
|---|---|---|---|
| Headshots and team photos | 1,200 to 1,600 pixels | JPEG, quality 80 | Under 150 KB |
| Full-bleed hero images | 1,920 to 2,400 pixels | JPEG, quality 75 | Under 300 KB |
| Blog post inline images | 1,200 pixels | JPEG, quality 80 | Under 150 KB |
| Charts, graphs, screenshots | As displayed | PNG for text and sharp edges, JPEG for photographic | Under 300 KB |
Upload targets for a Squarespace advisor site. These match the targets in the July 20 site speed post.
Three free tools do the work: TinyPNG (tinypng.com) for compressing JPEG and PNG files, Squoosh (squoosh.app) for fine-tuning with a side-by-side preview, and the resizer built into macOS Preview or Windows Photos.
The first full cleanup takes a few hours. After that it adds about a minute per image at upload. If you worked through the Squarespace site speed post, image compression was the biggest item on that list, and this is the detail behind it.
Headshots, team photos, and stock images
I think real photos of real people do more for an advisory firm than stock ever will. It is a trust business, and visitors can tell.
For the About and team pages, use professional headshots from the last couple of years. Name each file with the person's name, credential, and role. Write descriptive alt text. Compress before uploading. Of all the image work on the site, this matters most.
On service pages and posts where you have no relevant photo, stock is acceptable provided it does not undercut trust. An unrelated family on a beach, heading your retirement planning page, is worse than no photo.
When you do use stock, rename it. shutterstock-3984729.jpg becomes retirement-planning-couple-reviewing-financial-plan.jpg, and the alt text describes what is happening in the picture.
Charts, graphs, and infographics
Original charts are an undervalued asset on advisor sites. A chart of monthly Social Security benefit by claiming age, or a diagram of a withdrawal sequence, puts something distinctive on the page and gives AI engines something specific to cite.
- Make it readable on a phone. If the labels vanish at narrow widths, it helps no one.
- Save as PNG when the chart has text or sharp lines.
- Put a text caption underneath that states the takeaway.
- Name the file descriptively (social-security-claiming-age-monthly-benefit-chart.png).
- Write alt text that says what the chart shows, beyond the fact that it is a chart.
- Label hypothetical figures as hypothetical, and send the chart through compliance review like any other marketing piece.
Charts built on public data with your own framing (regional cost-of-living comparisons, scenarios typical of the people you serve) are more useful to a searcher than a generic chart copied from elsewhere.
Image SEO and AI search engines
I cannot see inside these systems, so I will keep this to what is checkable. An AI engine summarizing a page works from the page's text, and alt text, captions, and file names are text. An About page whose headshot is labeled with a name, a CFP® credential, and a city states those facts one more time in a place a machine can read.
That is the whole argument. Labeling images well costs almost nothing, it helps traditional search and accessibility regardless, and it leaves fewer gaps for an AI engine to fill by guessing. The rest of that work is in answer engine optimization for financial advisors.
The 15-minute image audit
Pick three pages
Homepage, About, and the service page or post with the most impressions.
Inspect every file name
Right-click each image. Note the generic ones.
Check every alt text
Inspect the image, or use a browser extension that shows alt text inline.
Run PageSpeed Insights
Note the Largest Contentful Paint for each page.
Fifteen minutes across three pages.
If any of the three pages has more than two images with generic names or missing alt text, you have about 30 minutes of fixing ahead. Afterward, watch those URLs in Search Console. Read impressions and average position, and compare a full 28 days after the change with the 28 days before.
Frequently asked questions
What is image SEO?
Image SEO is preparing images so search engines can understand them and pages load quickly. For an advisor site it comes down to three habits: a descriptive, hyphenated, lowercase file name, alt text that describes what is in the image, and a file resized and compressed before upload.
What should alt text say?
Describe what is in the image for someone who cannot see it, in under about 125 characters. For a headshot that means the person's name, credential, and setting. Do not repeat the firm name on every image, do not stuff keywords, and leave alt empty on purely decorative images so screen readers skip them.
What size should images be on a Squarespace advisor site?
Headshots and inline images: 1,200 to 1,600 pixels wide, under 150 KB. Full-width hero images: 1,920 to 2,400 pixels wide, under 300 KB. Charts and screenshots: PNG when there is text or sharp edges, under 300 KB. Resize and compress before uploading, because Squarespace will not shrink an oversized source file enough.
Do image file names matter for SEO?
Yes. The file name is the first thing a search engine reads about an image. IMG_4729.jpg says nothing, while shaun-melby-cfp-nashville-financial-advisor.jpg names the person, the credential, the city, and the role. Rename before you upload, use hyphens, keep it lowercase, and stay under about 60 characters.
Is it okay to use stock photos on an advisor website?
Yes, where you have no relevant photo of your own and the image does not undercut trust. Rename the file and write alt text describing what is happening in the picture. For About and team pages, use real, recent headshots. In a trust business, visitors can tell the difference.
The takeaway
Image SEO is unglamorous, and the biggest ranking gains usually come from elsewhere. It is steady, mechanical work that pays at the page level: faster loads, clearer signals to search engines and AI engines, and a small, real lift for every page you clean up.
