Landing Page / Destination Page – The web page at which a searcher arrives after clicking on an ad. When creating a PPC ad, the advertiser displays a URL (and specifies the exact page URL in the code) on which the will land after clicking on an ad in the SERP.

Landing Page Quality Scores - A measure used by Google to help filter noisy ads out of their AdWords program. When Google AdWords launched affiliates and arbitrage players made up a large portion of their ad market, but as more mainstream companies have spent on search marketing, Google has done many measures to try to keep their ads relevant.
Latent semantic indexing (LSI) - This mouthful just means that the search engines index commonly associated groups of words in a document. SEOs refer to these same groups of words as “Long Tail Searches”. The majority of searches consist of three or more words strung together. See also “long tail”. The significance is that it might be almost impossible to rank well for “mortgage”, but fairly easy to rank for “second mortgage to finance monster truck team”.
Lead Generation – Web sites that generate leads for products or services offered by another company. On a lead generation site, the visitor is unable to make a purchase but will fill out a contact form in order to get more information about the product or service presented. A submitted contact form is considered a lead. It contains personal information about a visitor who has some degree of interest in a product or service.

Link Building
The process of building high quality linkage data that search engines will evaluate to trust your website is authoritative, relevant, and trustworthy.
Link Bursts
A rapid increase in the quantity of links pointing at a website. When links occur naturally they generally develop over time. In some cases it may make sense that popular viral articles receive many links quickly, but in those cases there are typically other signs of quality as well, such as:
- increased usage data
- increase in brand related search queries
- traffic from the link sources to the site being linked at many of the new links coming from new pages on trusted domains
Link Churn
The rate at which a site loses links.
Link condom - Any of several methods used to avoid passing link love to another page, or to avoid possible detrimental results of indorsing a bad site by way of an outgoing link, or to discourage link spam in user generated content.
Link Equity
A measure of how strong a site is based on its inbound link popularity and the authority of the sites providing those links.
Link exchange
A reciprocal linking scheme often facilitated by a site devoted to directory pages. Link exchanges usually allow links to sites of low or no quality, and add no value themselves. Quality directories are usually human edited for quality assurance.
Link Farm

Link Hoarding
A method of trying to keep all your link popularity by not linking out to other sites, or linking out using JavaScript or through cheesy redirects.
Link juice (trust, authority, pagerank)
Link partner (link exchange, reciprocal linking) - Two sites which link to each other. Search engines usually don’t see these as high value links, because of the reciprocal nature.
Link Popularity
The number of links pointing at a website. For competitive search queries link quality counts much more than link quantity. Google typically shows a sample of known linkage data than the other engines do, even though Google still counts many of the links they do not show when you do a link: search. Link popularity a measure of the value of a site based upon the number and quality of sites that link to it
Link Reputation
The combination of your link equity and anchor text.
Link Rot

- A website going offline
- Linking to content which is temporary in nature (due to licensing structures or other reasons)
- Moving a page's location
- Changing a domain's content management system
Link spam (Comment Spam)
Unwanted links such as those posted in user generated content like blog comments.
Link text (Anchor text)
The user visible text of a link. Search engines use anchor text to indicate the relevancy of the referring site and link to the content on the landing page. Ideally all three will share some keywords in common.
Linkbait – Also known as link bait, this is something on your site that people will notice and link to. By linking to
your site, other sites are saying they value the content of your site and that they think other people will be
interested in it, too.
Linking Profile – A profile is a representation of the extent to which something exhibits various characteristics. A
linking profile is the results of an analysis of where of your links are coming from.
Log Files
Server files which show you what your leading sources of traffic are and what people are search for to find your website. Log files do not typically show as much data as analytics programs would, and if they do, it is generally not in a format that is as useful beyond seeing the top few stats.
Long Tail
Phrase describing how for any category of product being sold there is much more aggregate demand for the non-hits than there is for the hits.
Long-tailed Keywords – Keyword phrases with at least 2 or 3 words in them.
LSI LSI(Latent Semantic Indexing)
Latent Semantic Indexing is a way for search systems to mathematically understanding and representing language based on the similarity of pages and keyword co-occurance. A relevant result may not even have the search term in it. It may be returned based solely on the fact that it contains many similar words to those appearing in relevant pages which contain the search words.
