Meta descriptions and titles greatly influence Click Through Rate (CTR).
CTR is a strong ranking signal.
Ranking signals influence search rankings.
Therefore meta descriptions strongly influence rankings.
It's logical, really it is.
---------------------
The title catches their eye.
The URL triggers brand recognition, if any, and immediately incites trust or not (especially if you're on a freebie domain, have 4 or 5 hyphens in it, or a dropped domain name picked up and repurposed - like when you see an article about flea removal on a domain about north korean missile defense fundraising).
Meta description is what people usually use to decide whether they will click or not. It's your chance to get your value proposition across.
Meta description is where you focus on incredible price, selection, guarantee, and/or whatever USP's or items you've got that others don't.
Flea and Tick Dog Shampoo 250ml | Pets At Home
www.petsathome.com/shop/en/pets/flea-and-tick-dog-shampoo-250ml
Flea and Tick Dog Shampoo 250ml is available to buy online at Pets at Home, the UK's largest petshop with fast delivery and low prices.
I searched for flea shampoo for dogs and got this number one organically.
The title, url and start of meta description all point me to the fact it's what I'm looking for.
The meta description let's me know I can buy it online (essential if I'm shopping from home and don't want a trip to the shop), their brand (which is recognised), the fact they're the biggest, with fast delivery and a good price (not necessarily the best).
What they haven't done is shown any review stars, no mention of what brand the shampoo is, if it's vet recommended, hypoallergenic, best price, overnight or same day delivery, etc, etc.
They're a decent option and surely get massive CTR.

7 Jul 2016 - Hartz UltraGuard Rid Flea & Tick Shampoo for Dogs With Oatmeal. The Hartz UltraGuard Rid Flea & Tick Shampoo for Dogs with Oatmeal provides immediate relief from adult fleas and ticks, including deer ticks, which may carry Lyme disease. It contains Pyrethrins, which kills fleas and ticks that can carry diseases.
This one is giving me multiples - so if I'm trying to figure out which one to buy, they're review or category page will give me multiple choice with comparison of the best. Everyone wants the best, if it's cheap
Hartz is a recognised brand, so they're giving me a trusted brand, just so I know that they're not pimpin' out a bunch of never heard of snake oil choices to get rich quick.
They're also getting breadcrumbs / sitelinks (breadcrumbs to be accurate and oldschool). These are giving context out the wazoo. This is a massive advantage over obfuscated urls with long numbers and erroneous crap, or where the product is dropped into the root folder rather than nested in silos of logically sorted content.
There's a lot more to this than meets the eye - but this is a bit of an overview. Check out the course over on Fresh Bananas if you want the full scoop.
