Hello, this is a lifestyle design.
This time, I will talk about what kind of history the SEO has walked.
Please read it lightly to the degree of knowledge.
The search engine that cannot be cut off from SEO is the search engine.
First, the story of the search engine.
Yahoo and Google use the same search engine.
But this has a big background.
Originally, the search engines for Yahoo and Google were different.
Yahoo used a Goo (NTT) search engine until 2004.
However, Google was higher for search results.
Then, Yahoo then canceled a contract with Goo from 2004 to 2006 and borrowed a Google search engine.
Later, Yahoo began to use a unique search engine called YST (Yahoo Search Engine Technology).
But still, I wasn't at Google.
Google emphasized not only the number of backlinks but also the contents of the backlink site.
Not only quantity but also quality was emphasized, and panda -up dates (erasing sites like garbage) were performed.
On the other hand, Yahoo made the page rank judgment based on the number of backlinks on each site.
The SEO contractor who got there was a measure to make a lot of backlinks anyway.
YST was the pot of the SEO trader.
Since 2010, Yahoo has bought Google search engines and
has now used the same search engine.
As a result, around September 2011, many SEO companies that had erased backlinks were confused.
For future SEO measures, internal measures that emphasize the contents of the site and
external measures that emphasize backlink measures are important.
