Blogs typically record and categorize all content updates by date/time and topic for easy tracking by readers. The posts appear on a blog’s homepage in reverse-chronological order (thus the original term, “weblog”).
Another feature of blogging is a space reserved for comments (usually following every post). These interactive sections can often be longer, and sometimes more interesting, than the original post.

Click-Through Rate (CTR) – The percentage of people who actually click on a link (e.g., in an email message or sponsored ad) after seeing it.
Cloaking – A prohibited practice of tricking a search engine into indexing different content than the user actually sees. In essence, it is serving one version of a page to search engines (for intended SEO benefit) and another to humans.

Conversion – The desired action taken by a website visitor, such as making a purchase, registering for an event, subscribing to an e-newsletter, completing a lead-gen form, downloading a file, etc.
Conversion Cost – See “cost-per-acquisition (CPA)”
Conversion Rate – This is the percentage of visitors to a site or ad who actually take a further action, like buying a product or filling out a survey. For example, if your primary goal is to collect survey data through your site, and 20 people visit it, but only 5 people complete the survey, you have a conversion rate of 25%.

Still used today despite widely perceived diminishing relevance to search-engine rankings, the most common are the “title,” “description,” and “keyword” tags (see below).
Meta-Description Tag – A tag on a Web page located in the heading source code containing a basic description of the page. It helps search engines categorize the page and can potentially inform users who come across the page listing in search results.
Meta-Keywords Tag – In the past, this tag allowed page authors to insert a massive list of keywords related (and occasionally unrelated) to a page in order to game search-engine results. Today, this tag’s potential to influence rankings has diminished to the point where it is widely disregarded by major search engines.
Microblog – A microblog is a social media utility where users can share short status updates and information. The most famous example is Twitter, which combines aspects of blogs (personalized Web posting) with aspects of social networking sites (making and tracking connections, or “friends”).
Mirror Site – Duplicate copy of a website already in existence, used to increase response time for high-volume sites.
Nofollow – “Nofollow” is an append which is coded into the HTML markup of a hyperlink. It is used to prevent a search engine from indexing a link to a particular Web page.

Contrast with closed, propriety software that does not share its codebase beyond an exclusive group of authorized developers.
Organic Listings – These are search-engine results that have not been purchased. They are calculated solely by an engine’s algorithm and are based on the merits of the listed pages. Typically, most search engines will display several sponsored ads related to search terms (often separated by background color or otherwise highlighted) before displaying the non-paid listings.
Outbound Link – Any link on a Web page to an external Web page.
P4P – See "Pay for Performance"
PageRank – A former Google method for measuring the popularity of a Web page. Much-debated in the SEO community, the measurement is believed to be influenced chiefly by the number and quality of inbound and outbound links associated with a given page. Updated infrequently, this rank was indicated as a number between 1 and 10 most commonly displayed in a green bar chart in the Google toolbar add-on for browsers. The SEO community consensus opinion is that the measurement was nothing more than Google’s incomplete assessment of the relative strength of a website.
Paid Listings – Listings sold to advertisers for a fee. Also known as “paid placement.” See “pay-per-click.”
Paid Placement – See “pay-per-click.”
Pay for Performance – Pay for Performance Advertising, or P4P, is a term used to define a pricing model whereby a marketing or advertising agency receives payment for each new lead obtained through its online marketing efforts.
Pay-Per-Click – Also known as “PPC,” this type of paid search marketing involves placing advertisements that run above or besides (and occasionally below) the free search-engine listings on Google, Bing, and Yahoo!. Typically, to get the highest position among these ads, website owners place a per-click bid. It’s not uncommon to participate in a bidding war for coveted top spots. For example, if a website’s listing is among the top 3 advertisements on a page, the same ad appears in the same location on partner websites. Some marketing firms, including Fathom, provide bid management services to get the most value for each search term.
Pop-Up Ad – A form of advertisement which automatically opens (or “pops up” in) a new window in a browser to display an ad. Also seen in the form of “pop-under” ads, a slightly less intrusive version. These interruptive approaches to advertising are generally disliked (and therefore ignored) by Internet users. Many browser-based and stand-alone software programs exist to block these ads.

Also called “junk mail.” Spam may also refer to links or comments that are left on blogs, forums and message boards designed exclusively to steer users to a site for commercial gain. This kind of spam, generated by random visitors, is called link spam or comment spam.
In SEO, “spam” can be any Web page that a search engine views as harming the credibility of its results.
