If you have a bunch of content on a page, Google will hopefully index all of it, but it will consider it as a single page of text, not as separate pieces.
For more about this, check out the full post over on the Search Engine Roundtable blog.
There’s been discussion about this over the years, but Google’s John Mueller has made it clear — aside from some very rare situations, Google only indexes full pages of text. Among other things, he said:
“We don’t index parts of a page independently, we index the pages as a whole, and try to understand the context of the content there.”
Because of this, we often encourage people to break their services and products into separate pages. If you have a single page that lists all of your services, Google will consider the main focus of the page to be “Our Services” and you likely won’t rank well for the individual products.
However, if your main “Our Services” page has a bit of info about each service and then a link to a dedicated page for each service, you’ll likely rank much better.
For example, suppose you’re a copywriter. Your services might include website content, press releases, social media and blogging. If you have a page that focuses on each individual service, it’s more likely you’ll show up on Google when someone searches for “press release writer” because you’ll have a page focused on that, versus just a mention of it on your Services page among your other services.
Quality always beats quantity, but having more pages on your site, focused on your individual products and services, is likely a good way to go.
