Recall » Return to site
The portion of relevant documents that were retrieved when compared to all relevant documents.
Reciprocal Links » Return to site
Nepotistic link exchanges where websites try to build false authority by trading links, using three way link trades, or other low quality link schemes.
When sites link naturally there is going to be some amount of cross linking within a community, but if most or all of your links are reciprocal in nature it may be a sign of ranking manipulation. Also sites that trade links off topic or on links pages that are stashed away deep within their sites probably do not pass much link authority, and may add more risk than reward.
Quality reciprocal link exchanges in and of themselves are not a bad thing, but most reciprocal link offers are of low quality. If too many of your links are of low quality it may make it harder for your site to rank for relevant queries, and some search engines may look at inlink and outlink ratios as well as link quality when determining how natural a site's link profile is.
Redirect » Return to site
A method of alerting browsers and search engines that a page location moved. 301 redirects are for permanent change of location and 302 redirects are used for a temporary change of location.
Registrar » Return to site

Reinclusion » Return to site
If a site has been penalized for spamming they may fix the infraction and ask for reinclusion. Depending on the severity of the infraction and the brand strength of the site they may or may not be added to the search index.

Relative Link » Return to site
A link which shows the relation of the current URL to the URL of the page being linked at. Some links only show relative link paths instead of having the entire reference URL within the a href tag. Due to canonicalization and hijacking related issues it is typically preferred to use absolute links over relative links.
Example relative link
<a href="../folder/filename.html">Cool Stuff</a>
Example absolute link
<a href="http://bm-media.co.uk/folder/filename.html">Cool Stuff</a>
