The index used to increase the speed and performance of finding relevant documents by keywords. To create a search index in the first place, removed all tags and code. From these words are formed are sorted alphabetically (or by weight of the word in the case of a reverse index) lists and then carried out on the linguistic processing of words. Each word in the index corresponds to its weight.
Depending on the uniqueness of the content and availability of external links, the time required to add a site to the index search engine is usually a few days.
Indexing — is a database search system that is going robotic spiders and contains information about all known Internet resources in the form of text and multimedia structure. The process of making a website into a database is called indexing.
Indexing is necessary for efficient search of information in the network.
There are two ways of influencing the process of indexing your site:
- Using external links from popular sites or internal links from indexed pages;
- Manually – by filling and sending a special form.
To prevent indexing of some pages, user can use the file robots.txt, the file will not allow the crawler indexing of some pages.
- Index Page
Index page is called home page. Index page it is the most important part and should be the most informative.
Index Page unlike other pages, has the most weight as it most linked by resources and inner pages of the website. Therefore the inner pages linked from the Index page, will have a good weight and, therefore, will be well ranked in the search results.

There are other reasons for the impact on those or other parameters (age of the resource, a domain level, etc), but they are more important in the local development plan website.
- Internal Link
Internal link is a hyperlink on a website leading to another page of the same resource. All the internal links form the internal link graph of the site.
Using internal links can influence the redistribution of Link Weight (Link Juice) among the individual resource page. It is necessary to link to more relevant sections or articles. This redistribution of weight is called linking and is widely used by experienced SEOs as a part of internal optimization.
Internal links also help users of the site to simplify navigation, enable you to have access to any part of the resource and accelerate the entering of a visitor to a specific section. Proper internal linking is not only influence to search engines, but also care about users because it is one of the components of usability.
Unique address of a computer (server) in local network or Internet network, consisting of four integers (0 to 255 in decimal) separated by dots, e.g. 220.127.116.11. The numeric form of the address is used by computers, to humans, a numeric address is inconvenient, so it replaces the domain name.
In the hex representation of ip address is eight octets, where each octet is a hexadecimal number from 0 to F, the beginning is considered to be the right part.
For SEO ip-address is one of the key points, as a search engine, it is easy to determine which sites have the same ip and, consequently, to know the true owners of a network of sites for search engines is easy. When creating satellites, you need each site to assign a private ip address for safety and long-term effectiveness of the satellite.
Not all hosters allocate one ip address for one site, but place hundreds of sites on the same address, which is not always acceptable for SEOs.
