Quantitative factors are based on the unweighted number of backlinks to a site. The original PageRank algorithm is the best example for this kind of factors. There are three key metrics in this area:

• Link Popularity
• Domain Popularity
• IP Popularity

Using these figures to one for an entire domain , on the other, but also for individual sub-pages of a domain . Figures for entire domain resulting from the sum of the individual values ​​of the indicators all pages including the home page. In the following explanations is to simplify each of the term "web" is used.

Link Popularity

The term link popularity refers to the number of all the backlinks that point to a website. True to the motto: "Many links mean a high reputation" applies here: "The larger this number is, the better it is for the ranking of a website."

However, this figure is not considered particularly meaningful as a so-called site-wide links is now nothing unusual. A concrete example is the so-called blog Rolles. Here, a blogger linked, for example, a friend or other topics relevant blog of the navigation of his own blogs. This is the link to appear every bottom of his blog . Each of these links flows in link popularity with a. The origin of thought, a link is a special recommendation for further information diminishing role , because obviously the set in the blogroll link is not specific to the contents of a base.

Domain Popularity

The domain popularity is a measure that indicates the number of domains linked to a website. It does not matter how many times this site was linked from the pages of a domain. In order to defuse the problem of linking each base significantly. Also for the domain popularity is: the higher the ratio the more positive the impact on the ranking.

IP Popularity

Verschärftere a form of domain popularity is the IP Popularity dar. This measure all IP addresses are counted, from which links are placed on a website. This number was due to the fact that most web hosts a certain, limited IP range have available and make these available for different domains. It is possible that different domains are hosted on the same IP address.

Could be to increase the popularity of a website domain you now get the idea, simply register a number of different domains at a hoster and from these to the target site to link to. This would obviously manipulating the search engine algorithms take place because the set would link primary goal is to improve the ranking of the target website and thus does not actually possess value in terms of reputation increase.

The IP popularity there are in various forms. The version presented above is the least restrictive, since it merely requires that the IP addresses differ in any bit . In other variants, for example, a complete class C network (the first three octets of an IPv4 address) is chosen as the basis. However, in each variant also applies here, the principle that a high IP popularity has a positive impact on the ranking.

Conclusion

The quantitative factors of optimization Off Page give a rough overview of the link level or the popularity of a website on the Internet. The problem with these figures is the danger of manipulation. Although the manipulation attempts are hampered by restrictive perspectives, but by no means ineffective. There are, for example, already offers special hosting , domains which are hosted on different IPs of hundreds.

Another problem with these figures is that they unjustified discrimination may result. The simplest example of this are two different domains, the report on a common theme and are often mutually link - for example, because the other domain provides further information. In this case, that would be IP or domain popularity too restrictive , since it would be appropriate to evaluate each link, even if it comes from the same domain.

Because of these problems, one can assume that these metrics a first estimate of the Off Page optimization provide a website, but still not be the measure of all things.

This chapter discusses the use of HTML syntax to optimize the text on a web page. Already in The Anatomy of a Large-Scale Hypertextual Web Search Engine greater importance are excellent words separately metered and Google has continually evolved since that time.

Validity

It is irrelevant to the ranking, if a website is the W3C validation criteria or not.

HTML markup

HTML offers a wealth of opportunities to distinguish a text semantically. These include, for example, headings, lists, and bold or italic text passages. This award is a weighting of different keywords are induced.

Multimedia content

Images, videos and music, for example, fall into the category of multimedia. There are partially own search for this content. Besides optimizing for these there is also the theory that the use of images also have a positive impact on the organic search results has.

Contrary to some rumors, the validity of web pages according to the W3C a criterion that is used in the ranking of Google. 's Matt Cutts confirmed this in an appropriate screencast.

A majority of sites on the net does not contain a valid source , be it to support old browsers or because the validity in everyday life no importance is attached to. In general it can, however, of the validity of the source code is not close to the quality of the content and most current browsers provide even non-valid code correctly represents the consideration would lead to content that is potentially worse results because invalid websites would be disadvantaged.

The content for the search engines most interesting part of a Web page because it potentially contains the most information. One of the most common recommendations for search engine optimization (and one of the principles from Matt Cutts ) reads as follows: "Produce good quality content that is made ​​for people, then comes the success of search engines alone."

This statement may have been true in the early days of the Internet in this form, but with the development of Web 2.0 as no longer tenable. This is due to the fact that there are hardly a topic on which there is no information on the internet and secondly to the fact that the quality of content alone does not affect the ranking. It was the recommendation in the form of hyperlinks makes the content of a Web page for Google high quality. In addition, there are other factors that must be considered in the creation of content, because they have influence on the ranking.

A quote from Matt Cutts in ? How does Google collect and rank results provides an interesting approach, which serves as a general guide for the preparation of search engine optimized content:

Did fake you are a programme. decide a question like warfare or utilization or no matter you would like. seek for the phrase on Google, decide 3 or four pages from the results, and print them out. On every output signal, the individual words from your question notice (: like "civil" and "was") and use a highlighter to mark every word with color. do this for every of the 3-5 did you print out documents. currently Those documents tape on a wall, step back many feet, and squint your eyes. If you probably did not apprehend what the remainder of a page aforesaid, and solely may choose by the coloured words, that document does one suppose would be most relevant? Is there something did would create a document look a lot of relevant to you? Is it higher to possess the words be in {an exceedingly|in a very} giant or heading to an occur many times in a very smaller font? does one like it if the words square measure at the highest or the lowest of the page? however usually do the words got to appear? See if you'll come back up with 2-3 belongings you would hunt for to check if a document matched a question well. will|this will|this could|this may} facilitate students learn judge|to guage|to judge} connectedness web site the manner an enquiry engine would evaluate it thus thatthey can higher perceive why an enquiry engine returns sure results over others.

Keyword Density

The Keyword Density is a measure of the "density" of keywords within a web page. This figure is, however, be treated with caution.

Keyword Proximity and Keyword Positioning

Already in the early days of Google's proximity query ("proximity") was included in the ranking. Positioning refers to the naming in different parts of the semantic web .

Internal and external links

Linking to internal and external pages is important for two reasons. For one, the idea is to optimize the internal linking structures to ensure optimal PageRank flow to allow for other relevant links are included in the ranking (keywords: Good and Bad Neighborhood).

Semantic Relevance

The recognition of the semantics is the supreme art of information retrieval and the goal of any search engine. When a search engine (ie, its "sense"), knows the semantics of a text, they may search queries answered more focused and a user.
