Moved Permanently - The file has been moved permanently to a new location. This is the preferred method of redirecting for most pages or websites. If you are going to move an entire site to a new location you may want to test moving a file or folder first, and then if that ranks well you may want to proceed with moving the entire site. Depending on your site authority and crawl frequency it may take anywhere from a few days to a month or so for the 301 redirect to be picked up. See also: W3C HTTP 1.1 Status Code Definitions On Apache servers you can redirect URLs in a .htaccess file or via in the headers of some dynamic pages. Most web hosts run on Apache. On IIS servers you can redirect using ASP or ASP.net, or from within the internet manager.

Found - The file has been found, but is temporarily located at another URI. Generally, as it relates to SEO, it is typically best to avoid using 302 redirects. Some search engines struggle with redirect handling. Due to poor processing of 302 redirects some search engines have allowed competing businesses to hijack the listings of competitors.

Not Found - The server was unable to locate the URL. Some content management systems send 404 status codes when documents do exist. Ensure files that exist do give a 200 status code and requests for files that do not exist give a 404 status code. You may also want to check with your host to see if you can set up a custom 404 error page which makes it easy for site visitors to view your most popular and / or most relevant navigational options report navigational problems within your site Search engines request a robots.txt file to see what portions of your site they are allowed to crawl. Many browsers request a favicon.ico file when loading your site. While neither of these files are necessary, creating them will help keep your log files clean so you can focus on whatever other errors your site might have.

A term traditionally used to describe the top portion of a newspaper. In email or web marketing it means the area of content viewable prior to scrolling. Some people also define above the fold as an ad location at the very top of the screen, but due to banner blindness typical ad locations do not perform as well as ads that are well integrated into content. If ads look like content they typically perform much better. See also: Google AdSense heat map - shows ad clickthrough rate estimates based on ad positioning.

A link which shows the full 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 absolute link <a href="http://seobook.com/folder/filename.html">Cool Stuff</a> Example relative link <a href="../folder/filename.html">Cool Stuff</a>

Google AdSense is a fast and easy way for website publishers of all sizes to display relevant Google ads on their website's content pages and earn money. Because the ads are related to what your visitors are looking for on your site or matched to the characteristics and interests of the visitors your content attracts you'll finally have a way to both monetize and enhance your content pages. It's also a way for website publishers to provide Google web and site search to their visitors, and to earn money by displaying Google ads on the search results pages.
Google's contextual advertising network. Publishers large and small may automatically publish relevant advertisements near their content and share the profits from those ad clicks with Google. AdSense offers a highly scalable automated ad revenue stream which will help some publishers establish a baseline for the value of their ad inventory. In many cases AdSense will be underpriced, but that is the trade off for automating ad sales. AdSense ad auction formats include cost per click - advertisers are only charged when ads are clicked on CPM - advertisers are charged a certain amount per ad impression. Advertisers can target sites based on keyword, category, or demographic information. AdSense ad formats include text graphic animated graphics videos In some cases I have seen ads which got a 2 or 3% click through rate (CTR), while sites that are optimized for maximum CTR (through aggressive ad integration) can obtain as high as a 50 or 60% CTR depending on how niche their site is how commercially oriented their site is the relevancy and depth of advertisers in their vertical It is also worth pointing out that if you are too aggressive in monetizing your site before it has built up adequate authority your site may never gain enough authority to become highly profitable.

Google's advertisement and link auction network. Most of Google's ads are keyword targeted and sold on a cost per click basis in an auction which factors in ad clickthrough rate as well as max bid. Google is looking into expanding their ad network to include video ads, demographic targeting, affiliate ads, radio ads, and traditional print ads. AdWords is an increasingly complex marketplace. One could write a 300 page book just covering AdWords. Rather than doing that here I thought it would be useful to link to many relevant resources.

Google's CPC (Cost Per Click) based text advertising. AdWords takes clickthrough rate into consideration in addition to advertiser?s bid to determine the ad?s relative position within the paid search results. Google applies such a weighting factor in order to feature those paid search results that more popular and thus presumably more relevant and useful. Google has also started taking into account the quality of the landing page and applying a quality score to the landing pages.

Affiliate marketing programs allows merchants to expand their market reach and mindshare by paying independent agents on a cost per action (CPA) basis. Affiliates only get paid if visitors complete an action. Most affiliates make next to nothing because they are not aggressive marketers, have no real focus, fall for wasting money on instant wealth programs that lead them to buying a bunch of unneeded garbage via other's affiliate links, and do not attempt to create any real value. Some power affiliates make hundreds of thousands or millions of dollars per year because they are heavily focused on automation and/or tap large traffic streams. Typically niche affiliate sites make more per unit effort than overtly broad ones because they are easier to focus (and thus have a higher conversion rate). Selling a conversion is typically harder than selling a click (like AdSense does, for instance). Search engines are increasingly looking to remove the noise low quality thin affiliate sites ad to the search results through the use of algorithms which detect thin affiliate sites and duplicate content; manual review; and, implementation of landing page quality scores on their paid ads.

Some social networks or search systems may take site age, page age, user account age, and related historical data into account when determining how much to trust that person, website, or document. Some specialty search engines, like blog search engines, may also boost the relevancy of new documents. Fresh content which is also cited on many other channels (like related blogs) will temporarily rank better than you might expect because many of the other channels which cite the content will cite it off their home page or a well trusted high PageRank page. After those sites publish more content and the reference page falls into their archives those links are typically from pages which do not have as much link authority as their home pages. Some search engines may also try to classify sites to understand what type of sites they are, as in news sites or reference sites that do not need updated that often. They may also look at individual pages and try to classify them based on how frequently they change. See also: Google Patent 20050071741: Information retrieval based on historical data - mentions that document age, link age, link bursts, and link churn may be used to help score the relevancy of a document.
