Does Block Level Analysis Improve the Web Search Experience?

Block level analysis is an attempt to solve the faults in PageRank and Hyperlink Induced Topic Search (HITS). PageRank and HITS are one of the best algorithms used by major search engines like MSN to improve the performance of a web search. Block level analysis is a good method as it breaks down a web page into multiple nodes or points on the web graph. This method can surely help a SEO expert in his quest for optimizing web pages.
Block Level Analysis is Microsoft's attempt to improve the web search performance by optimizing the PageRank and HITS algorithms. It determines whether the content is a part of a navigation system or is page specific. This ranking system also presupposes that all links are not equal. It determines whether a link is a natural editorial link or advertisements. This analysis is conducted to ensure that advertisement links should not be counted as votes.
The whole idea behind block level analysis is that a web page can be divided into blocks with different topics. The relevance and weight of links are determined by its location within the blocks. By dividing web pages into blocks, web pages will not be counted as single, small units. Thus it will ensure a very good web search experience.
So what's the Importance of Block Level Analysis for an SEO company?
The block level analysis concept certainly delivers much better search results than current search results. However there are some problems associated with this method as search engine spiders only see text on a web page, while an average searcher sees a combination of pictures and text. Moreover, the concept is dependent on the presupposition that all web pages will have the same layout, but this cannot be applied to flash websites.
For SEO services, block level analysis will mean more optimized pages with good content and excellent link building strategies. Links that are relevant to the content of a web page will be taken into account. Search engine optimization services will have to adopt good and aggressive SEO policies to optimize a website.
