One of the least mentioned and advertised part of Search Engine Optimization is not so much getting a link on as many different pages as possible, but the keyword associated with the link, and the relevance that keyword has to the domain, url, or website it is being linked to.
Many individuals and indeed companies when venturing for a SEO services strategy often focus on the url, website or domain, and aim to ensure that the keywords associated with the url, as well as the description and title of the url are all relevant for an effective SEO campaign. This is all true and good, nothing wrong with efforts to ensure that every aspect of a website search engine optimization campaign, and to a domain, title, keywords and description (there is a thought that keyword should be no real place to focus in opposition to the title and description, if the search engine optimization is the main purpose of Google, because Google is more focused on than the title of the page keyword, in spite of this, other search engines do pay special attention to the keywords, would not hurt to leave them in the place), but also requires sufficient attention to paid to the relevant link text, URL, or Web site.
A key to Google’s algorithm, in fact, any search engine algorithm to determine the placement SERP (search engine results page) is close to the focus of keyword searches (i.e. How to appear in the page as soon as possible), and the keyword density (how often took place in a web page), taking into account that it is absolutely essential that any text or text link that is being implemented into a search engine optimization campaign choice of its domain name-related, or even SERP.
This is not enough, as long as the link to the Web site or the site, but link text to ensure that any site using the same spread of the title, description and keywords, as well as scattered in the body of the main page. This is one of the ways of determining if SEO services can do what they claim, simply showing them the site in question, and asking for an initial consultation.
