SEO Basics: Keywords, Meta Tags, Alt Text, and Indexing Explained

·

·

If you’re trying to grow your website traffic, understanding a few core SEO elements can go a long way. You don’t need to be a technical expert—just get familiar with the basics. In this post, we’ll walk through four essential SEO terms every small business should know: keywords, meta tags, alt text, and indexing vs. crawling.


1. Keywords

What they are:
Keywords are the words and phrases people type into search engines when they’re looking for something—like “custom wedding cupcakes” or “Chicago web designer.”

Why they matter:
Search engines scan your page for relevant keywords to figure out what it’s about. Use the right ones, and you’re more likely to show up in search results.

Quick Tip:
Use specific, relevant keywords naturally in your page titles, content, and headers.
Example: Instead of “Services,” use “Web Design Services for Small Businesses.”


2. Meta Tags

What they are:
Meta tags are pieces of code that help search engines understand your content. They also influence how your page appears in search results.

Main types to know:

  • Title Tag: This is the clickable headline in Google search results.
  • Meta Description: The short summary that appears underneath.

Why they matter:
They shape the first impression of your site and impact your click-through rates.

Quick Tip:
Write compelling, keyword-rich titles and descriptions for each page.
Use your CMS (like WordPress or Squarespace) to easily update them without touching code.


3. Alt Text

What it is:
Alt text is a short description of an image on your website.

Why it matters:

  • It helps visually impaired users who rely on screen readers.
  • It improves your image SEO—Google can’t “see” your images unless you describe them.

Quick Tip:
Describe what the image shows and include a keyword when it makes sense.
Example: “Chicago bakery storefront with custom cupcakes.”


4. Indexing vs. Crawling

Crawling:
When Google’s bots scan your site to see what content exists.

Indexing:
When your content is added to Google’s database, making it eligible to show up in search results.

Why it matters:
If your site isn’t indexed, it won’t appear in search results—no matter how great your content is.

Quick Tip:
Use Google Search Console to check which pages are indexed and troubleshoot the ones that aren’t.
