Hey ihave purchased some backlinks service, when i can see the changes in all seo tools sites? Thanks.
Every search engine is different, and it really depends on the quality of backlinks. They will probably show first with yahoo site explorer and may never show on google as they only show a portion of backlinks - which generally have to be of higher quality. If these were bulked purchased links, they might never show up with google.
Yahoo picks them in two or three days but for google it takes some time furhter you can check your webmaster tool to check links added or not yet .
It depends on the popularity of the pages where the links appear and how frequently they are spidered.
