Do meta descriptions matter when search engines rewrite them

Introduction

The advice arrives from both directions. One source says every page needs a carefully written description; another says search engines replace them most of the time so the effort is wasted.

Both observations are true and the conclusion drawn from them is usually wrong. Descriptions are not a ranking factor and are frequently rewritten, and they still influence whether somebody clicks often enough to be worth writing for the pages that matter. The answer is about which pages, not whether.

1. Do meta descriptions matter for ranking is a settled question

Deal with this first.

They are not a ranking factor and have not been for many years. Any advice built on the idea that inserting keywords there improves position is out of date and can be discounted entirely.

2. They matter for whether somebody clicks

The actual mechanism.

The description is the sentence or two beneath your listing, and it is read while a searcher decides between several results. It affects behaviour without affecting position, which is a real effect with a different measurement.

3. Expect them to be rewritten a good share of the time

Set the expectation honestly.

Search engines often generate their own summary, usually pulled from the part of the page matching the query. That is frequently a perfectly reasonable outcome, particularly for pages that rank across many different searches, where no single written description could suit every one of them.

4. Write them where the page has one clear purpose

The rule that decides where to spend the effort.

A service page, product page or landing page addresses one thing, and a written description will usually be kept and will usually be better than an extract. Broad articles ranking for dozens of queries are the ones most likely to be replaced.

5. Say what the page delivers, not what the company is

The most common weakness.

Descriptions opening with a company history spend the space on something the searcher did not ask about. State what somebody gets from this page, in specific terms.

6. Keep it in the length that displays

A practical limit.

Around one hundred and fifty to one hundred and sixty characters usually survives, and mobile listings show less. Front-load the substance so a truncated version still communicates the point.

7. Make sure every page has a distinct one

Duplicates are worse than absences.

Platforms frequently repeat a single site-wide description across every page. That is less useful than no description at all, because it guarantees the same uninformative text on every listing.

8. Do not leave them empty as a strategy

A conclusion sometimes drawn incorrectly.

Because search engines write good summaries sometimes, some people stop writing them entirely. On your most commercially important pages that hands over the one piece of the listing you fully control.

9. Measure the change in click-through rate

The only feedback that answers the question.

Record the current rate for a set of pages in your search console, rewrite the descriptions, and compare after a few weeks. This settles the argument for your own site rather than in general, which is the only version of the argument that has any bearing on what you should do next.

Review descriptions when the page itself changes substantially. A description written for a service you no longer offer in that form is worse than an automatically generated summary, because it is accurate about nothing.

Conclusion

Accept that descriptions do not affect ranking and do affect clicks, which puts them in the category of cheap improvements rather than essential work.

Expect frequent rewriting, concentrate the effort on pages with one clear purpose where your version will usually be kept, describe what the page delivers rather than who the company is, stay within the length that actually displays, give every page a distinct description, avoid leaving your most commercial pages to automatic summaries, and measure the effect on click-through rate for your own site rather than accepting a general claim.
