What the hidden data in a photo file does, what Google reads from it, and why the file name matters more than any of it.
Geotagging writes a location into the photo file itself, where software can read it and people can’t. It’s cheap, Posted Social does it on every client shoot, and it’s the smaller half of the job. The file name and the alt text are the bigger half, because they’re the parts an AI assistant can read and check, and showing up in AI search as a local service business comes down to giving it facts it can check.
What’s inside a photo file
A photo file holds more than the picture. Behind the pixels sit three layers of text, each written by a different tool and read by a different audience.
| Layer | Who writes it | What it holds | Who reads it |
| EXIF | Your camera or phone, automatically | Date, device, camera settings, and GPS coordinates if location services were on | Photo apps. Most websites and apps delete it when you upload |
| IPTC | A person, in editing software | Creator, credit line, copyright notice, caption, keywords | Google Images, which shows creator and credit beside an image search result |
| XMP | Editing software (Adobe’s format) | The same information as IPTC, in a newer format | Anything that reads IPTC. Google reads this version first |
Strictly speaking, geotagging is one line in the EXIF layer: the coordinates. Geotagging the way Posted Social does it means filling all three layers, because the coordinates are the part with the least proof that it helps, and the creator tag is the one Google has said in writing that it reads.
Does geotagging help local SEO?
It depends which claim you mean. Some of what you’ll hear about photo metadata has been confirmed by Google, some has been tested without a clear answer, and some is wrong. Here’s each pile.
What Google has confirmed
Google looks at three of the lines a person can type into a photo file: who took it, who gets credit for it, and who owns it. When one of those photos shows up in a Google Images search, Google can display that information beside it. Google also tells website owners to keep those three lines even when they wipe the rest of a file’s data to make it smaller.
For everything else about a photo, Google says to focus on the words attached to it that a person can see: the alt text, the caption, the text around it on the page, and the file name. That’s where Google’s own guidance puts the effort. Structured data is the other piece Google names. That’s the code that labels a page for machines, the same idea behind schema markup for local businesses.
On the coordinates specifically, Google’s search team has said in public that there’s no need to geotag images for SEO.
What’s been tested without a clear answer
The open question is whether coordinates inside a photo help your business rank higher on Google Maps. Local SEO practitioners have run multi-week tests to find out, and they disagree. One test found no change. Another found a small bump for “near me” searches and nothing else. Google hasn’t said anything either way.
One more wrinkle: when you upload a photo to your Google Business Profile, Google removes the coordinates from the file. So if Google uses them at all, it uses them in the moment you upload, before it throws them away.
What isn’t true
Geotagging by itself will not move your ranking on the map. And tagging photos with the coordinates of a town you’d like to work in won’t make Google show you there. When that was tested, rankings for searches that named those towns went down, not up.
The three things Posted Social writes into every photo
Every photo from a Posted Social shoot leaves with three things written into the file.
Coordinates. The business’s address as GPS coordinates in EXIF. This is the one the tests disagree on, and it goes in anyway. It costs nothing, and it means the photo and the Google Business Profile agree on where the business is.
Business data. Name, address, and phone number, typed into the file’s description lines and formatted exactly as they appear on the profile and the website footer. Keeping those details identical everywhere Google finds them is part of AI search visibility, and a photo file is one more place to get that right.
Creator tag. “Posted Social” on the creator line. This is the line Google shows in image results, and it stays with the file. A customer who reposts the photo, or a local paper that runs it, carries the credit along, because information inside the file goes wherever the file goes, and a caption stays behind.
None of the three replaces the file name. They’re the part that gets done once and ages well.
Why do file names and alt text matter more?
Because they’re plain text, and text is what search engines and AI assistants read without guessing. Metadata is inside the file. The file name is on the outside of it, and the alt text sits on the web page next to the picture. Crawlers, the programs search engines send to read pages, look there first.
The file name should say what’s in the photo, whose business it is, and where, in lowercase words separated by hyphens. Take the made-up plumber from the FAQ sections post:
- Before: IMG_4471.jpg
- After: acme-plumbing-tankless-water-heater-install-kirkwood-mo.jpg
The renamed file tells a crawler the business, the service, and the suburb before it opens the file.
Alt text is the written description a website stores with each image, originally for people who use screen readers. Write it as one sentence you could read aloud: “Acme Plumbing technician installing a tankless water heater in a Kirkwood, Missouri basement.” Not a keyword list, and not the file name again. It lives on the web page, not in the file, so you write it on your website, image by image.
The same rule behind writing blog posts that AI search cites applies here: a description that stands on its own gets quoted. One that needs the page around it doesn’t.
How to tag photos from a brand shoot
Nobody enjoys renaming ninety files after a shoot. The fix is doing the work before and during the shoot, so the files arrive already sorted.
- Write your shot list, the list of photos you plan to take, in words a customer would use. For each one, the service and the place: “tankless install, Kirkwood.” That list becomes the file names. If the shoot covers a month of posts, plan it from the PACE content allocation model.
- Copy the coordinates and the exact name, address, and phone from the Google Business Profile. Copied, not retyped.
- Shoot, pick the keepers, then tag. Only those get metadata. Editing software can add all three pieces of information to every photo in a folder at once, so this step takes minutes.
- Rename from the shot list. Business, service, place, and a number to tell them apart. Ninety files that follow one pattern can be renamed in one pass, not one at a time.
- Write alt text at upload. It lives on the page, so it can’t be done in advance.
Posted Social runs this on every content production shoot. The shot list is the step most businesses skip, and the one that makes the other four fast.
Where the photos go, and what survives the upload
Metadata survives on your own website and almost nowhere else, which is one more reason the file name carries the weight.
| Destination | What survives | What to do |
| Your website | The file you upload keeps its metadata. The smaller copies your site makes for different screens often lose it | Upload the full file. Write alt text on every image |
| Google Business Profile | Deleted when you upload | Name the file first. It’s the only text that goes in with the photo |
| Directories (Yelp, Apple Business Connect, Bing Places) | Usually deleted | Upload the same renamed file and fill in any caption box they give you |
| Facebook and Instagram | Deleted | The caption and location tag do the job instead |
Start with the photos you already have
Find the twenty photos on your website that show your best work. Rename them the way the file name section describes: business, service, place. Add alt text, and re-upload. Then upload the same twenty to your Google Business Profile with the new names. That’s an afternoon, and it puts a good file name and alt text, the two things with the most evidence behind them, on the images customers already see.
The metadata is for your next shoot, when the files are new and the editing software can tag them all at once. If you’d rather hand the whole sequence off, Posted Social handles naming, tagging, and alt text in every SEO and AI optimization engagement. Contact Posted Social to start with the next shoot.
