301 Redirect - Permanent way to redirect a page
AdWords - Google’s keyword research tool
Anchor text - Hyperlinked text
Your hyperlinked text should always be concise and relevant to the page you’re linking to, as well as to your own site. This helps search engines see how people understand your content. So whenever you link internally, or when you ask partners to link to your website, you want to be sure the anchor text is a relevant keyword or phrase.
Authority - Calculated credibility
H1 tag - Breaking up content into sections and subsections helps search engines to determine what the major and minor points are. This also improves the user experience for readers who are more likely to skim through your content than reading it word for word.
Keyword Density - % related keywords
Landing Page - The first page someone lands on when they get to your site. This could be chosen by you and should not necessarily be your home page.
Long Tail Keyword - 3-4 keyword phrases which are very, very specific to what your business is about. The more specific the phrase, the more targeted the audience and more likely they are to convert when they get to your site.
Meta Description - A brief summary of your article that appears under the main headline in the search results page. It is like a preview to your content and should be the most exciting bit of it all. Meta descriptions should be short and up to 160 characters or less to optimise for mobile.
Organic traffic - Traffic that comes to your site via search and not paid traffic
SEM - Search Engine Marketing
SEO - Search Engine Optimization
SERP - Search Engine Results Page
Sitemap - A list of all your site’s URLs in XML file form.
