The digital head at a mid-sized fund house opens Search Console on a Monday and filters the report to image search. The SIP-versus-lump-sum infographic, the most shared asset the team made all year, barely shows up. The file is called final-v7-approved.png. It has no alt text. Every return figure sits inside the pixels, and the page around it says only “see the chart below”. Google has almost nothing to read. Image SEO for a financial brand is mostly the work of putting a chart’s facts into text that a search engine, an AI answer and a compliance reviewer can all read.
What you need before you start image SEO on a finance site
Before anyone renames a file, image SEO needs four named owners, one agreed approval route and a short list of inputs. Without them the work stops at the first chart that carries a return figure.
Two definitions first. Image SEO is the set of choices that help search engines find an image, understand what it shows and match it to a query: the file itself, its name, its alt text, the words around it and the markup on the page. Alt text is the short written description stored in the image’s HTML, read aloud by screen readers and used by Google to understand the picture. Google’s image SEO guidance calls alt text the most important metadata for an image.
Name these four people in writing:
- The web or SEO owner, who controls templates, filenames, the sitemap and structured data.
- The design lead, who exports the files and keeps the editable source of every chart.
- The data owner, usually someone in the product, fund or actuarial team, who confirms every number and its as-of date.
- The compliance reviewer, who approves the chart and, just as important, the words that will sit around it.
The inputs are a list of every image on your money pages and blog, last quarter’s Search Console data filtered to image search, the approved source document behind each chart, and your claims register if you keep one. A claims register is a sheet listing every number, rate and rule your site states, with its source and approval date. If you have none, the inventory in step one becomes its first draft.
Agree the approval route before the first export. Compliance should know that each chart will now carry a filename, alt text, a caption and a summary paragraph, and that all four count as published copy. In our experience, teams that skip this conversation get the chart approved and then wait again for the text.
Phase one: every chart starts with an inventory and a source line
The first phase changes nothing visible on the site. It produces a list, and that list sets the pace for everything after it.
Step 1. List every image that states a fact. Crawl the site or export the media library, then keep only the images that carry a number, a rate, a rule or a product claim: return charts, premium tables saved as pictures, fee comparisons, eligibility flowcharts and ratio infographics. Decorative photos can wait. For each image record the page it sits on, the filename, whether it has alt text and whether the same figures appear anywhere in the page text.
Step 2. Tie every figure to a source and a date. Next to each image, write the document the numbers came from (a factsheet, a product brochure, a key facts statement, a board-approved rate card) and the as-of date. Mark any chart whose source no one can find. Those come down or get rebuilt; an engine will quote a stale figure as readily as a current one.
The second step is where image SEO meets regulation. A mutual fund chart that shows returns is an advertisement, and SEBI’s mutual fund advertisement code requires the standard risk warning to appear in it. An insurer’s product infographic is usually an advertisement too, and the IRDAI regulations on protecting policyholders’ interests, issued in 2024, require every insurer advertisement to show the insurer’s registered name with its trade name or logo prominently. A lender’s loan-cost chart should match the key facts statement, which RBI requires lenders to give borrowers before the loan contract is signed, annual percentage rate included. Your inventory should flag which of these applies to each image.
Keep the inventory as a spreadsheet. It becomes the working file for every later step and every refresh.
If a number lives only inside the pixels, nobody can correct it without a designer, and no engine can quote it with confidence.
Phase two: engines read the text around a chart, more than the chart itself
Google reads an image through its HTML, its filename, its alt text and the words placed near it. Phase two puts the chart’s facts into all four, in three steps.

Step 3. Publish each chart as a real image element with a plain filename. Google’s image guidance says it finds images in the src attribute of an img element and does not index images set as CSS backgrounds. Many finance sites put hero charts and calculator results in CSS backgrounds or in a slider script, and those are invisible to image search. Rename files to describe the content in short, lowercase words, for example sip-vs-lump-sum-10-year-illustration.png. Google lists BMP, GIF, JPEG, PNG, WebP, SVG and AVIF as supported formats. If you serve sizes through srcset, keep a fallback src.
Step 4. Write alt text that says what the chart shows. Keep it to one sentence that names the chart type, the subject and the period: “Bar chart comparing a hypothetical ₹5,000 monthly SIP with a one-time ₹6 lakh investment over ten years.” Do not paste the whole data set into alt text, and do not stuff it with keywords; Google warns against that. Alt text on a regulated chart is published copy, so it goes to compliance with the chart.
Step 5. Put a text summary or data table beside every chart. W3C’s accessibility tutorial on complex images recommends a two-part text alternative for charts and infographics: a short description in the alt text and a long description elsewhere, ideally visible in the main content. For a finance page the long description is a two-to-four sentence summary under the chart, or the underlying figures in an HTML table, with the source and as-of date in plain text.
Step five carries the most weight, and it is where the regulated decisions show. Take a hypothetical return chart on a fund page. The standard SEBI warning is baked into the bottom of the image, which is fine for the image. Put it in the page text as well, in the exact approved wording, directly under the chart summary. Engines and screen readers then read the warning next to the returns, and a crop or a thumbnail in an AI answer cannot separate the figure from the warning on your own page.
The same decision applies to insurers. If an infographic explains claim settlement steps, the registered name and logo lockup belongs in the image, and the registered name should also appear in the visible caption. For a lender’s EMI chart, write the annual percentage rate in the summary exactly as the key facts statement gives it, with the as-of date. When the summary and the chart disagree, the summary wins in search, because that is the part an engine quotes.
One more choice: infographics with a lot of text work better as a sequence of smaller images, each with its own alt text and summary, than as one tall poster. A tall poster gets one alt text and one thumbnail. Five panels get five chances to match five questions.
Phase three: markup and sitemaps tell Google which image matters
Once the chart and its text are in place, the third phase tells Google which image represents the page and who owns it. This is step six, and it has three parts.
Step 6. Mark up the preferred image, the licence and the sitemap entry. Specify the page’s preferred image through schema.org markup such as primaryImageOfPage, or through the og:image tag. Add image licence metadata: Google supports structured data or embedded IPTC photo metadata that names the creator, the credit line, the copyright notice and a licence URL, and a licence URL is needed for the Licensable badge in Google Images. Then list chart images in an image sitemap, which Google supports for images it might otherwise miss, including images on a CDN.
Three details trip finance teams up here. First, Google’s image guidance advises against using images with text as the preferred image for a page. A text-heavy infographic makes a poor og:image; a clean chart or a branded illustration without small print makes a better one, while the infographic stays in the body with its alt text.
Second, Google’s structured data policies say markup must be a true representation of the page content and must not describe content readers cannot see. If your markup says the chart shows a 12-month return, the visible summary must say so too, in the same words. Third, the image sitemap format Google documents today needs only the image location tag. The older caption, title, geo-location and licence tags have been removed from Google’s documentation, so put that information on the page and in structured data instead.
Phase four: a chart with a dated number needs a refresh rule
A finance chart goes stale the moment a rate, a NAV or a premium changes. The fourth phase is one step, and it never ends.
Step 7. Refresh the chart, its alt text and its summary on the same day. Set a rule for each image type in the inventory: return charts with each factsheet cycle, rate charts whenever the rate card changes, product infographics whenever the product document is revised. On refresh day, export the new file, update the alt text, caption and summary, change the as-of date and send all of it to compliance as one row.
Filenames need a decision of their own. Google’s image guidance asks you to reference an image by the same URL across pages so it can cache and reuse it. Our practice is to keep one URL per chart for as long as the data holds, and when the figures change, publish a new file with the new as-of month in the name, swap every reference on the same day and update the sitemap. That way the old figure stops appearing under your current pages, and nobody quotes last year’s rate from an image that still sits on a forgotten blog post.
Tie this rule to the claims register. When the data owner changes a figure there, the register should list every image that carries it. A rate cut in the register with no matching chart refresh is how an outdated EMI example ends up in an AI answer.
The seven image SEO steps at a glance
The table lists each step with its owner, a typical time and the artefact to keep for audit. The timings are typical practice for a site with a few dozen fact-bearing images, not a regulator’s standard; a large bank or insurer site will take longer.
| Step | Owner | Typical time | Artefact to keep |
|---|---|---|---|
| 1. List every image that states a fact | Web or SEO owner | Two to four days | Image inventory sheet |
| 2. Tie every figure to a source and date | Data owner | About a week | Inventory with source and as-of columns, linked to the claims register |
| 3. Publish as a real image with a plain filename | Web owner and design lead | One to two days per template | Filename convention and template change log |
| 4. Write alt text for each chart | Content or SEO owner, then compliance | A few days, plus review | Approved alt text column in the inventory |
| 5. Add a summary or data table beside each chart | Content owner, data owner, compliance | One to two weeks including review | Approved summaries with disclaimer wording and source lines |
| 6. Mark up the image, licence and sitemap | Web or SEO owner | Two to three days | Structured data test results and sitemap file |
| 7. Refresh on a set rule | Data owner, with compliance | Ongoing, per data cycle | Refresh log with dates and approver names |
How long image SEO takes and who signs off
For most finance sites, the first pass of image SEO takes four to six weeks from inventory to markup in our experience. Review time, not production, decides the length.
The production work is quick. Renaming files, fixing templates and adding markup is a few days of web work once the inventory exists. The summaries and alt text take longer because each one states a regulated fact in new words, and each needs a reviewer. In our experience, teams that send summaries in batches of ten or twenty, grouped by product, get faster turnarounds than teams that send them one page at a time.
Sign-off runs in two lines. The data owner signs that each figure, as-of date and source line is correct. Compliance signs the chart and its text layer together: alt text, caption, summary and any disclaimer placed under it. The web owner signs nothing regulatory but keeps the change log, which is the record you will be asked for if a figure is ever questioned.
How to tell image SEO worked
You can tell image SEO worked when image search impressions rise for the pages you fixed, and when engines describe your charts using your own summary wording. Neither proves revenue on its own, so track both against a fixed baseline.
- Image search data in Search Console. Google’s Performance report has a search type filter for web, image, video and news, and shows clicks, impressions, click-through rate and average position. Compare the fixed pages for the eight weeks before and after the change.
- Structured data validation. Run the pages through Google’s Rich Results Test and fix every error on the image and licence properties.
- AI answer checks. Keep a fixed panel of buyer questions, such as “how does a SIP compare with a lump sum over ten years”, and record each month whether AI answers cite your page and quote your summary. Google says AI Overviews and AI Mode have no extra requirements beyond a page being indexed and eligible to show with a snippet, so clean, readable chart pages are the work that counts.
- Accuracy checks. Search for your old figures. If an engine still quotes a rate you changed, find the image or page carrying it.
Be careful with claims to the board. No one can promise an image ranking or an AI citation, and Google says meeting its requirements does not guarantee crawling, indexing or serving. Report what moved and what the panel shows. Our AI Search and GEO work uses the same fixed-panel method for whole sites, and the GEO and AEO FAQ for financial brands covers how AI answers choose sources.
What to do when an image SEO step fails
Most image SEO failures on finance sites come from four places, and each has a plain fix.
The chart is indexed but never shown. Check the alt text and the summary. If both are vague (“chart”, “graph showing returns”), the image matches nothing a buyer types. Rewrite both around the question the chart answers, then request indexing again.
Compliance rejects the summary but approved the chart. This usually means the summary says something the chart only implies, such as “beats inflation”. Rewrite the summary to describe only what the chart plots, with the source and date, and keep comparisons for the approved product copy.
The wrong image appears as the page thumbnail. Google picked a text-heavy infographic or a logo. Set a preferred image through markup or og:image, choose a clean visual without small print, and make sure it is high-resolution.
An AI answer quotes an old figure. Find every page and image carrying it, including old blog posts and PDFs. Update or retire them on the same day, refresh the sitemap, and log the change. If the old figure sits on a third-party site that copied your chart, the licence details from step six tell them where the current version lives.
What to tell your compliance team about image SEO
Compliance approves this work faster when it sees the scope in one paragraph. Paste this into an email and edit it.
We are making our charts and infographics readable to search engines. Each image will carry a descriptive filename, one sentence of alt text, a caption and a short summary or data table stating the same figures as the chart, with the source and as-of date. Disclaimers and the standard warning in each image will also appear, in the approved wording, as text under the chart. Nothing in the text claims more than the chart shows. You will receive each chart and its text as one row in a shared sheet, and we will keep a refresh log with your approval date for each change.
This is general guidance, not legal advice; your compliance team decides what each page must carry.
If your brand also needs to be visible inside AI answers more broadly, our AI visibility programme for BFSI brands starts with the same inventory.
People also ask
Does alt text help a financial chart rank in Google Images?
Yes, it is one of the strongest signals you control. Google’s image guidance calls alt text the most important metadata for an image and asks for informative, natural wording without keyword stuffing. For a regulated chart, treat alt text as published copy and get it approved with the chart.
Should a mutual fund put the standard warning in the image or in the page text?
Put it in both. SEBI’s advertisement code requires the standard warning in mutual fund advertisements, so it belongs in the image, and repeating the exact approved wording as text under the chart keeps the warning next to the returns for engines and screen readers. Your compliance team confirms the final placement.
Do infographics still matter for SEO when AI answers give the response?
They matter if the facts inside them are also written as text on the page. Google says AI Overviews need nothing beyond a page that is indexed and eligible for a snippet, and a chart with a clear summary gives an engine something accurate to quote. An infographic with no text around it adds little.
Can a finance brand use one image URL across many pages?
Yes, and Google’s image guidance recommends referencing the same image by a consistent URL so it can be cached. When the figures change, publish a new file with the new as-of month in its name and swap every reference on the same day, so no page keeps showing the old number.
