Yahoo! Search Support for X-Robots-Tag Directive to Simplify Webmaster’s Control and Weather Update
Today we’re announcing support for tags that give webmasters even more flexibility over which pages and documents are crawled and indexed by Yahoo! Search. Specifically, we’re extending our support of page level exclusion tags — NOINDEX, NOARCHIVE, NOSNIPPET, NOFOLLOW — to provide additional control for archiving and summarization of ANY file type. ――
Along with this change, we’ll be rolling out additional changes to our crawling, indexing and ranking algorithms over the next few days. We expect the update will be completed early next week, but you may see some changes in ranking as well as some shuffling of the pages in the index during this process.
とのことで、来週頭くらいに終わるらしい。
最近のヤフーの順位は？な部分が多かったのでこの更新に期待したい！
