More impressions in Search Console means your pages appeared more often in Google Search under the report's counting rules. It does not mean the extra appearances were equally relevant, or that more people visited your website.
Before changing a title or rewriting a page, find out where the increase came from.
Keep the comparison consistent
Open Performance, then Search results, in the correct property. Compare equal completed periods. Keep the search type, country and device filters consistent.
An impression, a click and an average position describe different things. Google defines how these measures are counted, including cases where results behave differently.
Avoid drawing a conclusion from today's incomplete figures or a handful of impressions.
Find the pages behind the increase
Use Pages to identify which pages gained impressions. Select one, then inspect its Queries.
A hypothetical florist might see more appearances for a wedding flowers page. Searches for "wedding florist Bristol" could be useful enquiries in waiting. A rise in "paper flower templates" would suggest a different audience.
The site-wide total cannot make that distinction for you. Review the searches and the page together.
Some query detail may be withheld in reports, so do not assume the visible rows explain every impression.
Check whether the result matches the page
Read the page title and description in your website editor. Do they explain what the customer will find? Does the page itself deliver that information?
A workshop page should make the activity, location, dates and booking route easy to understand. Adding popular phrases that the page does not answer can make the result less useful.
Google can generate a title link and snippet from several sources. Your editor's preview does not guarantee the exact result someone will see.
Separate visibility from business results
If clicks and relevant enquiries are steady, rising impressions alone may not require an urgent change.
If a valuable page has lost clicks, investigate its searches, devices and dates. Check whether the offer changed, whether demand is seasonal and whether the page still works.
Choose an action that follows from the evidence. Clarify an ambiguous title, update a stale workshop date or leave a relevant, functioning page alone while you gather more data.
After a change, revisit the same page and filters over a suitable completed period. Record clicks and actual enquiries alongside impressions. A larger visibility total is only part of the picture.
