SEO Resources

Search engines use a combination of algorithms to deliver ranked webpages via a results page based on a number of factors and signals.

The text description of an image on a web page. It's used by both screen readers and search engines, so it’s important for both accessibility and SEO. Also called “alternative text” 

The visible clickable text of a hyperlink. Google uses anchor text to better understand the content of the linked page.

Links from other websites that point to your website. Also called “inbound links”

Search engine optimization practices that violate Google’s quality guidelines.

These scour the Internet to find, crawl, index, and order web content. Also known as search engine “crawlers” or “spiders” 

The percentage of visits that did not result in a secondary action on your site. For example, if someone visited your home page and then left before viewing any other pages, that would be a bounced session.

The different mediums by which your website can get attention and acquire traffic, such as organic search, paid advertising, social media, and email campaigns.

The “rel=canonical” tag allows site owners to tell Google which version of a web page is the original and which are the duplicates.

The ratio of impressions to clicks on your URLs. Google may show your website 1000 times but if only 100 users click to the link to visit your site, your click-through rate is 10%.

The process of optimizing a site’s content strategy for search engines. This includes doing keyword research, optimizing meta tags with target keywords, and developing new content as needed.

The ratio of visits to conversions. Conversion rate answers how many of my website visitors are filling out my forms, calling, signing up for my newsletter, etc.

Is a “you link to me and I’ll link to you” tactic. Excessive link exchanges are a violation of Google’s quality guidelines. Also called “reciprocal linking”

Google began progressively moving websites over to mobile first indexing in 2018. This change means that Google crawls and indexes your pages based on their mobile version rather than their desktop version.

A snippet is the title and meta description preview that Google shows of URLs on its results page. A “rich” snippet, therefore, is an enhanced version of the standard snippet. Some rich snippets can be encouraged by the use of structured data markup, like review markup displaying as rating stars next to those URLs in the search results.

A file that tells search engine bots which parts of your site they should and shouldn't crawl.
