Sometimes. Google builds snippets primarily from page content and uses your meta description only when it judges yours describes the page better. On 24 Tamil Nadu engineering college homepages that exposed meta tags, 8 carried no description. Of the 25 that resolved a title tag, none was missing one.
Sometimes, and less often than the advice around this question implies. Google's snippet documentation says it builds the text under a search result primarily from the page content, and reaches for the meta description only when that element describes the page better than the page does. It is an option you hand Google, not an instruction Google follows.
What does Google actually do with the tag?
Google states that snippets are created automatically from page content, and that they preview the part of the content best matching a specific search. That is why one page shows different snippets for different queries. Your description enters that process as a candidate.
On length, the documentation is blunter than most advice about it.
"There's no limit on how long a meta description can be, but the snippet is truncated in Google Search results as needed, typically to fit the device width."
So any exact character count you have been handed is somebody's working convention. Ours is 140 to 155 characters, which we use for consistency across a site. It is a house rule of ours, not a threshold Google publishes. The guidance is worth reading directly rather than through a summary of it in Control your snippets in search results.
Which field actually goes missing?
We fetched 30 Tamil Nadu engineering college homepages as raw HTML, no JavaScript executed, in a single pass in late August 2026. A title tag resolved on 25 of them and a meta block was exposed on 24. Those two sets are not identical, so their counts cannot be added.
| Field | Sites where the field was resolvable | Missing or unusable |
|---|---|---|
| Title tag | 25 | 0 |
| Meta description | 24 | 8 |
| Meta description present but unusable | 24 | 2 |
Not one site was missing a title. A third of the sites exposing a meta block had nothing in the description. Both fields sit in the same few lines of HTML, so the gap is not technical difficulty. Our reading is that a CMS writes the title by default while a description needs someone to write it deliberately, though we did not record which CMS each site runs.
Neither of the two unusable descriptions would look broken on a dashboard:
- One was the bare domain name, sitting where a placeholder was never filled
- One was an empty tag

A title on a page with nothing behind it
Two of the 25 sites that returned a title tag returned no readable body content at all. The title arrived. The page did not.
That matters more than a missing description. Google's title link documentation states that where it cannot access the content on a page, it falls back to off-page content such as anchor text from other sites. Those two homepages hand Google a claim about the institution with nothing on the page to check it against. Google draws on nine sources to build a title:
- Content in title elements
- The main visual title shown on the page
- Heading elements, such as h1
- Content in og:title meta tags
- Other text made large and prominent through style treatments
- Other text contained in the page
- Anchor text on the page
- Text within links that point to the page
- WebSite structured data
Google's own worked example of a title it rewrites is an admissions page: a title element still reading 2020 admissions criteria while the visible heading says 2021. The cases it corrects are listed in Influencing your title links in search results.
Where the body is built by JavaScript, the prior question is whether a crawler sees it at all.
Who is answering this question on page one?
We pulled the Google India results for the query meta description on 3 September 2026 through the Ahrefs SERP index. Seven organic results appeared in the top 10, and an AI Overview sat above all of them.
| Source of the answer | Organic results in top 10 | Sources cited by the AI Overview |
|---|---|---|
| Companies selling SEO or web services | 5 | 6 |
| Google's own documentation | 1 | 1 |
| General HTML reference | 1 | 0 |
"Every page-one result defines the meta description or explains how to write one. None reports what the field looks like on real sites in a real market."
So what should a college actually do?
The check takes about two minutes per page and needs no tooling beyond a browser.
- 1
Start with the homepage and the admissions page, because those carry the queries that convert
- 2
View source and search for the description meta tag, counting an empty tag as missing
- 3
Write the description to describe the page rather than to hit a character count
- 4
Check the title says what the page is, and check the year if the page carries one
- 5
Confirm the body text is present in the raw HTML, not assembled after load
The counts above come from engineering colleges only. We have not measured arts and science colleges, schools or polytechnics, and would not assume the numbers transfer. A separate fetch three weeks earlier found the same pattern in a different sample of the same population, reported in what most Tamil Nadu engineering college sites get wrong, which counted 12 of 30 homepages with no meta description.
"The two studies report the same pattern on different samples. They do not share a denominator or a site list, so the two sets of figures should never be merged into one."
We run the same fetch on any institution site and send the result unedited, with nothing attached to it. How we work with institutions is set out on our schools and colleges page.
Key takeaways
- Google uses the meta description sometimes, not always, and generates most snippets from the page itself
- Google publishes no character limit for the field and truncates snippets to the device width
- Across 24 Tamil Nadu engineering college homepages exposing meta tags, 8 had no description and 2 had one that was unusable
- Across the 25 resolving a title tag, none was missing, which suggests the field that survives is the one nobody has to remember to write
- Two homepages served a title tag with no readable body behind it, leaving Google a claim it cannot verify on the page
Frequently asked
Will writing a meta description improve our ranking?
Google's snippet documentation describes the field as a source for the snippet, not as a ranking factor. The gain is in how accurately your result describes the page, and whether a parent clicks it, rather than in position.
How long should a meta description be?
Google states there is no limit, and that the snippet is truncated as needed to fit the device width. We work to 140 to 155 characters for consistency across a site, but that is our own convention rather than a Google standard.
Our CMS fills the title automatically. Is that enough?
Often, but not always. Google names half-empty titles, obsolete titles and repeated boilerplate as cases it corrects. An automatic title carrying last year's admission year is the example Google itself uses.
Does this apply to schools and arts colleges?
We measured Tamil Nadu engineering colleges only, on one date, with one instrument. The pattern is worth checking on any institution site, but these counts should not be quoted for a population we did not sample.
Can you check our site and tell us what it says?
Yes. We run the same fetch on any institution site and send the result back unedited, with nothing attached to it.
