Do meta descriptions help my Google ranking?

Not directly, Google does not use them to rank pages. They decide whether someone clicks your listing or the one below it, which is where the phone calls come from.

I wrote a description but Google shows different text. Did I do it wrong?

Probably not. Google swaps in its own snippet when it thinks other page text matches the search better, and it does this a lot. Check the page with View Page Source. If your text is in the meta tag, your side is done.

Can I use the same description on every page?

No. Each page competes for different searches, so each needs its own pitch. A duplicate description on your drain cleaning page wastes the two lines that could have sold drain cleaning.

Do I need to hire someone for this?

Not for a typical small business site. If you can type into a form, you can do this in your site builder in an afternoon. Hiring makes sense only when you have dozens of pages or no access to the site login.

Meta descriptions: the 150 characters that sell the click

What a meta description actually does

A meta description is the gray text under your business name in a Google search result. It does not move your ranking. Google has said for years that it is not a ranking factor. What it does is sell the click. When someone in Pewaukee searches "water heater replacement near me," every plumber on that page gets the same size listing. The one whose two lines say something specific gets the call.

Two numbers to remember: Google shows roughly 155 characters on a desktop screen and closer to 120 on a phone before it cuts the text off with "...". Most of your customers search from a phone, so the important words go up front.

If you skip writing one, Google grabs whatever text it thinks fits, which is how contractors end up with their cookie notice or footer copyright showing under their name in search results.

See what yours say right now

Open Google and search: site:yourwebsite.com (use your real domain, no space after the colon). Google lists every page it has indexed from your site, each with the description it currently shows. Read them like a customer would.

To see what your site actually sends Google, open any page, right-click a blank spot, choose View Page Source, then press Ctrl+F (Cmd+F on Mac) and search for the word "description". You are looking for a line that starts with <meta name="description". If it is not there, the page has none.

You will find one of three things on most local business sites:

Nothing at all, so Google improvises with random page text
The same sentence copied onto every page, usually the homepage tagline
Auto-generated junk from the theme or builder, like the first 20 words of the page

Field note

Fix pages in this order: homepage first, then your three biggest service pages, then any city or service-area pages, then contact. That covers where nearly all your search traffic lands.

The formula for a local service business

Four parts, in order: what you do, where you do it, one specific reason to pick you, and what to do next. That is the whole formula.

A filled-in example for an HVAC company: "Furnace and AC repair in Delafield, WI. Family-run, licensed, and we answer the phone on weekends. Call for same-week service." That is 126 characters, which survives the phone cutoff intact.

One for a roofer: "Roof repair and replacement across Waukesha County. Written estimates with photos of every stage, and we handle the insurance paperwork." That is 136 characters.

Notice what is not in there: "best in Wisconsin," "your trusted partner," "welcome to our website." Superlatives say nothing because every competitor claims them. Specifics like "upfront flat-rate pricing, no trip charge" or "we answer weekends" do the selling. Write the thing you say on the phone when a customer asks why they should hire you.

Skip double quotation marks inside the text, they can break the tag on some sites
No ALL CAPS, Google can rewrite listings that look like ads
Do not cram in every city you serve, pick the one the page is about
Each page gets its own description, never copy one across pages

Add them in your site builder

Every major builder has a field for this. You type into a box and hit save, no code involved.

WordPress: install the free Yoast SEO plugin (Plugins > Add New > search "Yoast SEO" > Install > Activate). Then edit any page, scroll to the Yoast SEO box below the editor, and fill in the Meta description field. The free Rank Math plugin works the same way if you already have it.
Wix: open the editor, go to Pages & Menu, click the three dots next to a page, choose SEO basics, and fill in the description field.
Squarespace: go to Pages, hover over the page, click the gear icon, open the SEO tab, and fill in SEO Description.
GoDaddy Websites + Marketing: open Edit Website, go to Settings > Search Engine Optimization and work through the prompts, or open a page's settings and look for the SEO section to set it per page.
Custom-built site: the description is one line inside the page's head section, <meta name="description" content="your text here">. Whoever maintains the site can add it to each page, it is a small edit, not a project.

Check the length, publish, and confirm Google sees it

Count characters before you save. Paste your draft into a Google Doc and open Tools > Word count, which shows a character count. Or use the free SERP Simulator at mangools.com, which previews exactly how your title and description look in a Google result, no signup needed. Aim for 120 to 155 characters, with the service and city inside the first 120.

Publishing the field does not update Google the same day. Google re-reads pages on its own schedule. You can nudge it: in Google Search Console (free at search.google.com/search-console, and worth setting up anyway), paste the page address into the URL Inspection bar at the top, then click Request Indexing.

A week or two later, rerun the site:yourwebsite.com search and check that your new text is showing.

When Google rewrites what you wrote

Google reserves the right to ignore your description and pull page text it thinks matches the search better. Ahrefs studied this in 2020 and found Google rewrote the description around 63% of the time. So expect it, and do not assume something is broken when the text under your listing does not match what you typed.

Writing one is still worth the ten minutes per page. Google leans on your description most for the searches that matter, the ones that match what the page is squarely about. Keep each page on one topic, make the description match what the page actually says, and your version shows up for your money searches even if Google improvises on the long-tail ones.

Once Search Console has a few weeks of data, open Performance > Pages and watch click-through rate on the pages you rewrote. If a page gets plenty of impressions but few clicks, the listing is not selling. Rewrite the description with a sharper specific and check back.
