nofollow

nofollow is a value that can be assigned to the rel attribute of an HTML a element to instruct some search engines that a hyperlink should not influence the link target's ranking in the search engine's index. It is intended to reduce the effectiveness of certain types of search engine spam, thereby improving the quality of search engine results and preventing spamdexing from occurring.

The nofollow value was originally suggested to stop comment spam in blogs. Believing that comment spam affected the entire blogging community, in early 2005 Google’s Matt Cutts and Blogger’s Jason Shellen proposed the value to address the problem.

SEO Technology

SEO technology comes in several different varieties including coding, tools and applications, widgets and files. Using SEO technology to code a website properly is important so that search engine robots can properly crawl and index a website.

Perhaps the SEO technology that search engine optimizers use most are tools and applications for doing their jobs.

SEO toolbars, Wordpress plug-ins and back link checkers are some common bits of SEO technology needed in order to serve the client. There are many toolbars that work with either Internet Explorer and Firefox browsers that will scan a page and deliver results such as keyword density, back link information and ranking data just to name a few.

SEO technology really starts with the keyword research. Apps such as Wordtracker, Keyword Discovery, Google AdWords Keyword Tool and at one time the Overture Tool (before it took a dive) have all been valuable SEO technology for uncovering keywords that people use in their online searches.SEO technology that have become popular in the last few years. Widgets, if coded and promoted properly can be used as link bait to attract many links to a client site.

SEO technology has come a long way since the early days of keyword stuffing the meta tags and throwing a bunch of nonsensical text at the bottom of a page

Page Rank Algorithm

Google PageRank Algorithm

The most popular way for PageRank algorithm to rank websites. Algorithm developed and Sergey Brin and Larry Page of the 90s were published by Stanford University at the end. PageRank can be understood as a website's importance. Ranking algorithm is a function of factors on and off the page. - On page factors title, description, headings and plain text are, for example. PageRank and anchor text from off-page factors (incoming links) is. Neither the content nor the URL (such as off-page criteria, called factors) plays a role. In addition, there is no difference between internal and external links.

The citation (link) graph of the web is an important resource that has largely gone unused in existing web search engines. Google created maps containing as many as 518 million of these hyperlinks, a significant sample of the total. These maps allow rapid calculation of a web page's "PageRank", an objective measure of its citation importance that corresponds well with people's subjective idea of importance. Because of this correspondence, PageRank is an excellent way to prioritize the results of web keyword searches. For most popular subjects, a simple text matching search that is restricted to web page titles performs admirably when PageRank prioritizes the results (demo available at google.stanford.edu).

Assume page A has pages T1...Tn which point to it (i.e., are citations). The parameter d is a damping factor which can be set between 0 and 1. We usually set d to 0.85. There are more details about d in the next section. Also C(A) is defined as the number of links going out of page A. The PageRank of a page A is given as follows:

PR(A) = (1-d) + d (PR(T1)/C(T1) + ... + PR(Tn)/C(Tn))
Note that the PageRanks form a probability distribution over web pages, so the sum of all web pages' PageRanks will be one.

PageRank or PR(A) can be calculated using a simple iterative algorithm, and corresponds to the principal eigenvector of the normalized link matrix of the web.
f the PageRank value differences between PR1, PR2,.....PR10 were equal then that conclusion would hold up, but many people believe that the values between PR1 and PR10 (the maximum) are set on a logarithmic scale, and there is very good reason for believing it. Nobody outside Google knows for sure one way or the other, but the chances are high that the scale is logarithmic, or similar. If so, it means that it takes a lot more additional PageRank for a page to move up to the next PageRank level that it did to move up from the previous PageRank level. The result is that it reverses the previous conclusion, so that a link from a PR8 page that has lots of outbound links is worth more than a link from a PR4 page that has only a few outbound links.

Web Designing

The web designing services need to be such that the website becomes efficient and effective at not only converting the visitor into buyer but also at retaining the current buyers. Some of the basics for successful web design services are as follows.

Buyer :
The services should be buyer oriented. What is the use of the web design that does not cater to the needs of the buyer? The final consumer has to be always considered prime for effective website designing services. All the customers do not have a stereotype attitude. Some of the products need images to impress the buyer while in some case the images are not needed at all. The buyer behavior varies according to the age of the targeted audience too.

Technology :
Appropriate technology needs to be used for maximizing the downloading speed. The quicker the download, the faster is the response from the prospective buyer. The technology factor becomes vital at embedding the images on to the website. There is no use of image that cannot be downloaded at the user's end and not seen by the prospective buyer. While most of the technologies used for embedding the images are not considered for indexing the search engine list there are a few image embedding codes that are now being considered by the search engines.

Resolution :
Sometimes the web design services result in a website whose resolution does not match with that of the computer at the buyer's end. If the resolution cannot be accommodated the visitor needs to scroll horizontally and vertically. The situation becomes critical when the designer forgets to add the scroll bar. The website design should be compatible with higher resolutions such as 1024 x 786 and at the same time lower resolutions such as 800 x 600. It is better to have a monitor with these resolutions and check the presentation of the website.

Billing :
Web design services sector is becoming a big buck industry. The business identities want to woe the customers/clients at any cost. This does not mean that the web designing company can take the business identity for a ride. Sooner or later the business owner is going to be aware of the truth and this can adversely affect the professional relationship. The hidden costs should be avoided by declaring them before signing of contract. Usually the taxes are not declared. It is better that the service offering company clarifies this with the prospective website owner otherwise it can adversely affect the goodwill of the company.

Flexibility :
The web design services company should offer a package that is flexible and not rigid. The prospective website owner should come to know how much each service could cost individually and how much it could cost collectively in the package. It is better to clarify the terms and conditions and the services included in the package before offering the services. The web design company needs to be somewhat flexible at the payment terms and conditions.
