ABCDEGHIKLMNOPQRSTU

A

Alt text

A short written description of an image, read by screen readers and used by search engines to understand the image. Good alt text describes the image plainly.

Anchor text

The visible, clickable words of a link. Descriptive anchor text helps readers and search engines understand what the linked page is about.

B

Backlink

A link from another website to yours. Links from relevant, trustworthy sites can help a page be found, while low quality or paid links can cause harm.

Bounce rate

The share of visits where someone views a single page and leaves without further interaction. On its own it is a weak signal and should be read in context.

C

Canonical tag

A line of code that tells search engines which version of a page is the preferred one, used to avoid duplicate content problems.

Citation (local)

A mention of a business name, address, and phone number on another website or directory. Consistent citations support local search visibility.

Click through rate

The share of people who click a result after seeing it. A clear title and description can improve it.

Conversion

A desired action a visitor takes, such as a call, a form submission, or a purchase. SEO work is judged against conversions, not traffic alone.

Crawling

The process by which a search engine robot discovers and reads pages on the web by following links.

A third party score, created by SEO tool vendors rather than Google, that estimates a site strength. It is an estimate, not an official ranking factor.
