No meta description means Google pulls a snippet from wherever on the page seems relevant, sometimes the nav menu, sometimes a sentence that makes no sense out of context. TechySEO checks every page on your site for the five ways this goes wrong, including the templating bug that quietly breaks a perfectly good description.
Skip it and Google fills the gap itself, usually by lifting a sentence from wherever on the page seems closest to the query. Sometimes that's a fine summary. Often it's an out-of-context fragment, or worse, a line of navigation text that made it into the snippet because nothing else on the page looked more relevant. Either way, you didn't write it, and it's representing your page in the one place a searcher decides whether to click.
Two pages sharing the same description is a quieter version of the same problem: nothing in the SERP gives a searcher a reason to prefer one over the other. And length cuts both ways. Past 155 characters, Google truncates mid-sentence with an ellipsis, usually right where the actual selling point was about to land. Under 70, and there's barely enough room to say anything persuasive at all.
Every unused character in that 120-to-155 range is click-through rate left on the table, on a page that's already ranking and just not getting clicked as often as it should.

Run the audit and find the missing descriptions, the duplicates, and the one a stray quotation mark quietly broke.
