Image SEO for Financial Advisors: Alt Text, File Names, and Size
Most advisor websites have an image SEO problem the owner has never thought about. Photos uploaded straight from a phone or a stock library, named something like IMG_4729.jpg, with no alt text, weighing two megabytes each. Multiply that by a homepage, three service pages, an About page, and a dozen blog posts, and the issue compounds quickly.
Image SEO is one of the easiest wins on an advisor website. The work is mechanical. The signals it sends are real. And the speed improvements often move other rankings as a side effect.
This post covers the three image SEO problems advisor sites consistently have, what to do about each one, and what changes when AI search engines start reading your images.
Why images matter for advisor SEO
Images influence search performance in three ways, and most advisors only think about the first.
The obvious one is image search itself. When someone searches Google for "fee-only financial advisor Nashville," a small percentage of those searches surface image results. An advisor headshot with the right file name and alt text can appear in those results and drive a click.
The less obvious one is page speed. Unoptimized images are the single biggest cause of slow advisor sites. Slow pages lose impressions because Google demotes them on mobile. Site speed is a confirmed ranking factor, and the easiest way to fix it on most advisor sites is to compress and resize images.
The newest one is AI search. When ChatGPT, Perplexity, and Google's AI Overview generate answers, they sometimes parse alt text and image context to understand a page. Pages where images are properly labeled give AI engines more material to work with when deciding what your firm does and who you serve.
For most advisor websites, the page speed angle alone is worth the time.
The three image SEO problems advisor sites have
After auditing hundreds of advisor websites, the same three issues show up almost every time.
Problem 1: Generic file names
Photos uploaded with names like IMG_2843.jpg, DSC_0091.JPG, or shutterstock-stock-photo-4928374.png tell Google nothing about what the image shows. The file name is the first signal a search engine reads when crawling an image.
Problem 2: Missing or useless alt text
Alt text serves two purposes: it describes the image for visually impaired users using screen readers, and it gives search engines context for what the image shows. Most advisor sites either skip alt text entirely or fill it with the firm name on every image, which helps nothing.
Problem 3: Massive file sizes
Modern phones produce images that are 3,000 to 5,000 pixels wide and several megabytes in size. Squarespace will display them, but it sends the full-size version to mobile users on slow connections. The page loads slowly. Google notices. Rankings suffer.
The fix for each is straightforward once you know what to do.
File names that help Google understand the page
Before you upload an image, rename it. A good file name is short, descriptive, hyphenated, and lowercase.
Bad: IMG_4729.jpg Better: shaun-melby-headshot.jpg Best: shaun-melby-cfp-nashville-financial-advisor.jpg
The third version is what should be used on the About page where the image lives. It tells Google the photo shows the firm's founder, his credential, his location, and his role.
A few simple rules:
Use hyphens between words, not the underscore character or spaces
Keep names under 60 characters or so
Describe what's in the image, not what page it's on
Lowercase everything
Avoid generic words like "image" or "photo"
This takes about 30 seconds per image and is the single highest-value image SEO action you can take.
Alt text rules for advisor sites
Alt text should describe what is actually in the image, written for someone who cannot see it. Search engines read it the same way.
Good alt text for an advisor site:
"Shaun Melby, CFP®, founder of Melby Wealth Management, in a navy suit at the firm's Nashville office"
"Sample retirement income spreadsheet showing a tax-efficient withdrawal sequence"
"Map of greater Nashville with markers showing the firm's primary service area"
Bad alt text for an advisor site:
"Melby Wealth Management" (every image, regardless of content)
"Financial advisor" (too generic)
(blank)
A few rules to live by:
Describe what is in the image, not what page it lives on
Keep it under about 125 characters (screen readers cut off after that)
Don't keyword-stuff. "Nashville financial advisor fiduciary fee-only CFP retirement planning" is worse than a clean human description.
Skip alt text for purely decorative images (background patterns, divider lines) by leaving alt="" so screen readers skip them
On a typical advisor site, alt text fixes take an hour or two for the entire site.
Image size and compression for Squarespace
This is where most of the speed gains come from.
Squarespace serves images at responsive sizes automatically, but only up to the dimensions of the file you uploaded. Upload a 5,000-pixel-wide image and Squarespace will send something close to that to large displays. Upload a 1,800-pixel-wide image and Squarespace can never send a larger one than that.
The right approach for most advisor sites:
Headshots and team photos. Upload at 1,200 to 1,600 pixels wide. Compressed JPEG at quality 80. File size should land between 100 and 250 KB.
Full-bleed hero images. Upload at 1,920 to 2,400 pixels wide. Compressed JPEG at quality 75. File size should land between 200 and 400 KB.
Blog post inline images. Upload at 1,200 pixels wide. Compressed JPEG at quality 80. File size under 200 KB.
Charts, graphs, and screenshots. PNG format if the image has text or sharp edges. JPEG if it is photographic. Always under 300 KB.
Three free tools handle this work:
TinyPNG (tinypng.com) for compressing JPEG and PNG files
Squoosh (squoosh.app) for fine-tuning compression with a side-by-side preview
Image Resizer built into macOS Preview or Windows Photos for resizing before compression
Run every image through this process before uploading. The first time you do a full site cleanup it takes a few hours. After that, doing it once per image as you upload takes an extra 60 seconds.
If you went through our site speed for Squarespace post, image compression was probably the biggest single fix on that list. This is the work.
Headshots, team photos, and stock images
Real photos of real people perform better than stock photography on advisor websites, for both conversion and SEO.
For your About page and team pages, use professional headshots taken in the last two years. Name them with the person's name, credential, and role. Write descriptive alt text. Compress before uploading. This is the highest-impact image work on the site.
For service pages and blog posts where you do not have a relevant photo, stock images are acceptable as long as they don't undercut trust. A photo of an unrelated family on a beach for your retirement planning page is worse than no photo at all.
When using stock, rename the file before uploading. shutterstock-3984729.jpg becomes retirement-planning-couple-reviewing-financial-plan.jpg. Alt text describes what is happening. The stock origin is invisible to Google once you handle it correctly.
Charts, graphs, and infographics for SEO
Original charts and graphs are one of the most undervalued image assets on an advisor website.
A custom chart showing tax-efficient withdrawal sequences, or a graph showing the impact of starting Social Security at different ages, gives Google something distinctive on the page. It also gives AI search engines something specific to cite when your post comes up as a source.
A few rules for charts on advisor sites:
Make the chart readable on mobile. If labels disappear at narrow widths, it does not help anyone.
Save as PNG, not JPEG, when the chart has text or sharp lines
Include a text caption underneath that summarizes the takeaway
Name the file descriptively (social-security-claiming-age-monthly-benefit-chart.png)
Write alt text that describes the chart's content, not just its existence
Charts created with the firm's own data (anonymized client situations, regional cost-of-living comparisons, scenarios specific to your typical clients) outperform generic charts from a search standpoint.
Image SEO and AI search engines
AI engines like ChatGPT and Perplexity read alt text when parsing a page. Image filenames and surrounding text also feed into how the page is summarized.
For an advisor whose goal is to be cited when someone asks an AI for "financial advisor recommendations in Nashville," properly labeled images give the model more material to work with. The model can see that the page contains a photo of a CFP®, that the firm is in Nashville, that the services include retirement income planning, and so on.
This is one place where image SEO has compounded over the last two years. Pages that were already labeled well for traditional search are showing up in AI search results without any additional work. Pages that were labeled poorly are largely invisible to AI engines.
The 15-minute image audit
Pick your three highest-traffic pages (homepage, About, and your most-visited service or blog page). For each page:
Right-click each image and inspect the file name. Note any with generic names.
Hover over each image to see the alt text (or use a browser extension like Web Developer to display alt text inline).
Check page load time on PageSpeed Insights and note the largest contentful paint score.
If any of the three pages has more than two images with generic file names or missing alt text, you have a 30-minute fix ahead of you that will probably move impressions on those pages within four to six weeks.
After making changes, watch Google Search Console for those specific URLs. The signals to track are impressions and average ranking position. Per our standing rule on GSC data, query-level clicks and CTR are unreliable because of Google's privacy throttling. Impressions and average position are what move.
The takeaway
Image SEO is not glamorous, and it is not where the biggest ranking gains usually come from. It is consistent, mechanical, and high-impact at the page level. A site with clean image SEO loads faster, communicates better to search engines and AI engines, and gives every page a small but real signal boost.
