Alt text for every image
One clear sentence per photo, written after viewing it, with decorative images marked so screen readers skip them.
The Problem
Your Photos Look Great, but Google Can't Tell What's in Them
Most sites upload images straight from a camera or a designer's export. Search engines then find heavy files with names like IMG_4021, and alt text that's either empty or a list of keywords.
Empty alt
Most images have empty alt text or a keyword list.
Empty alt
A person views each image and writes one plain sentence about it.
Camera files
Photos upload at full camera size and slow every page.
Camera files
We resize to the widths your layout uses and convert to WebP or AVIF.
Hidden photos
Key photos sit in CSS backgrounds that Google doesn't index.
Hidden photos
We move photos that should rank into img tags with a fallback src.
File names
Files named IMG_4021 tell search engines nothing.
File names
Key images get short, descriptive names, and new uploads follow a naming rule.
You've paid for product shots, venue photos, or a portfolio, and none of them appear when people search Google Images. Open the media library and you'll find files named IMG_4021.jpg, uploads straight from a camera, and alt text that's empty or stuffed with keywords. Your theme shows some photos as CSS backgrounds, which Google doesn't index. Pages crawl on phones because a huge image fills a small box. Every week they sit there, those photos cost you speed and send nobody to your site.
We start by viewing every image where it actually appears, so each alt text says what the photo shows in that context. Then we rename key files, convert them to WebP or AVIF at the sizes your layout really uses, and move photos that should rank out of CSS backgrounds. An image sitemap lists them for Google. Your photos load faster and finally describe themselves, instead of sitting in search as IMG_4021.
Every image viewed first
Alt text describes what each photo shows on its page, not a guess from the file name.
Lighter files, same quality
Modern formats and right-sized versions cut page weight without visible loss on phones or retina screens.
Photos Google can find
An image sitemap and proper img tags surface photos that galleries and scripts used to hide.
Our Image SEO Process
From Free Image Review to Findable, Faster Photos in Five Clear Steps
You approve the image list and a sample of alt text before we write the rest. Nothing changes on your live site until you've seen it in a sheet or on staging.
We crawl your site, count the images on each template, and check file sizes, formats, alt text, and which photos sit in CSS backgrounds. You get a fixed price, the image count, and the heaviest images listed by page.
What's Included
What You Get With SEO Image Optimization
Every plan covers alt text, file names, formats, sizes, and indexing, so your photos help rankings and page speed instead of dragging both down.
Compare Options
DeveloperLook vs Alt Text Plugin vs Freelancer
An alt text plugin is quick and cheap for a big library, and a careful freelancer can handle a small site well. Here's where each one fits and where it falls short.
| Feature | DeveloperLookBest fit | Alt Text Plugin | Freelancer |
|---|---|---|---|
| Alt text quality | Written per image, checked by a person | Auto captions, often generic | Good if they view each image |
| Page context | Checked where each image appears | Reads the image file only | Varies by person |
| Decorative images | Given an empty alt on purpose | Usually described anyway | Sometimes handled |
| File names | Key files renamed, references updated | Not included | Often skipped on live files |
| Compression and formats | WebP or AVIF at layout sizes | Some plugins compress too | Depends on their tools |
| Image sitemap | Set up and submitted | Some plugins add one | Rarely included |
| Speed of delivery | 1 to 3 weeks by image count | Minutes once installed | Varies with workload |
| Cost | Fixed price from $450 | Free or a small monthly fee | Often cheaper for small sites |

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built and improved websites for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
Why Teams Trust Us With Their Image Libraries
We look at your photos the way a visitor and a search engine would, so the work reads well to people and gives Google clear signals.
We look before we write
Every alt text line starts with someone viewing the image on its page. That's how a photo of your blue ceramic vase stops being called product image 3.
Plain words over keywords
We describe what's in the picture and name a product or place only when it's really there. Google's image guide warns against stuffing alt text, and so do we.
Screen readers come first
Alt text serves blind and low-vision visitors before it serves search. Purely decorative images get an empty alt, so screen readers skip the filler.
No broken image links
When we rename a file, every page, gallery, and product that uses it updates too. If your CMS can't do that safely, we keep the old name and tell you why.
Checked on real phones
We review image quality and load order on mid-range phones, not just a fast laptop. Compression stops where a photo would start to look soft.
Your originals stay safe
We back up every original image before we touch it. You keep the originals, the new versions, and the full alt text sheet.

Good fit
Online stores with large product catalogs
You sell hundreds of products, and nobody has touched your product images' SEO since launch, so every alt text just repeats the product name.
Photographers, artists, and portfolio sites
Your work is visual, but your gallery pages rank for nothing because the images carry camera file names and no alt text for SEO.
Hotels, venues, and vacation rentals
Your room and venue photos sell the booking, yet they load slowly on phones and don't appear when guests search Google Images.
Teams fixing an accessibility report
Your accessibility scan flagged hundreds of missing alt attributes, and you want them written well enough to help search too, not just to pass a checker.
Agencies with image-heavy client sites
Your client's site holds thousands of images, and you need alt text and compression done under your brand without pulling designers off projects.
Not a fit
Whole pages need rewriting
You want titles, headings, and page copy rewritten, not just images fixed. Our On-Page SEO Services cover the full page, including its images.
Slow pages, not slow images
Your pages are slow because of scripts, hosting, or a heavy theme rather than photos. Website Speed Optimization handles the whole load, images included.
Full WCAG fixes needed
You need full WCAG remediation with forms, contrast, and keyboard fixes, not only alt text. Accessibility Remediation Services cover every success criterion.
Budget under $450
Your site has fewer than 50 images, or your budget is under $450. If your CMS's alt text field and a free compressor already cover your case, we'll tell you before we quote.

Frequently Asked Questions
Straight answers on alt text, file names, compression, duplicate images, and what the work costs.
Saimul IslamFounder & CEO, DeveloperLookStill have questions?

Projects start at $450 for sites with up to 250 images. The Search-Ready Images plan costs $950 for up to 1,000 images and adds srcset sizes and an image sitemap. Full Image Library costs $1,450 for up to 3,000 images, with a duplicate image review and a naming guide. Bigger catalogs get a fixed quote after the free image review.
Most projects take 1 to 3 weeks, depending on how many images you have. A site with up to 250 images is usually done in about a week. Libraries of 1,000 to 3,000 images take 2 to 3 weeks, because a person views and checks every alt text line. The clock starts once you approve the 20-image sample.
Image optimization in SEO means making each image easy for search engines to understand and quick for visitors to load. It covers alt text, file names, formats, dimensions, and where the image sits on the page. SEO for images also includes an image sitemap, so Google can find photos that galleries or scripts load after the page.
Yes, images help SEO when they're described, sized well, and placed near related text. They can bring visitors from image search and make a page more useful. Badly handled images do the opposite: heavy files slow the page, and empty alt text leaves Google guessing. Google Image SEO also favors original photos over stock files found on thousands of sites.
Yes. Google says it uses alt text together with computer vision and the page's content to understand an image, and the correct name is the alt attribute. Alt text also works as anchor text when an image is a link. Image alt text SEO comes down to one habit: describe the picture in plain words, without a keyword list.
Yes, a little. Google's image guide says short, descriptive file names give it clues, while names like IMG_4021.jpg say almost nothing. Renaming live files can break links, though. We rename key images only where your CMS updates every reference, and we give your team a naming rule so new uploads arrive ready.
Compression affects SEO through page speed. Google's image guide notes that images are often the largest part of a page's size. A slow main image also hurts Largest Contentful Paint, one of the Core Web Vitals. We compress to WebP or AVIF at the sizes your layout uses, and we stop before photos look soft on a retina screen.
No, duplicate images aren't a penalty, but they waste a chance to stand out. When one file appears on many pages, Google suggests referencing it with the same URL each time so it can reuse it. Stock photos make weak SEO images, though, because so many sites use the same file. Original photos give image search something new.
It rarely causes a ranking penalty, but it carries other risks. Images copied without a license can bring a copyright complaint and a forced removal. Hotlinking another site's file means its owner decides whether it loads. A copied photo also adds nothing new for image search to rank, so use your own or properly licensed images.
Only as a drafting aid on large libraries, with a person checking every line. AI captions often describe a photo vaguely or miss what matters, such as the exact product or the venue. In our alt text writing services, a person views each image in context and approves or rewrites every line before it reaches your site.
