Let me explain that question: I have a blog, and I try to post something new on it every day. I noticed that some of my blog post rank very high for some very un-competitive keywords on the first couple of days after posting them. Then, days later, the blog post disappear from the first ten pages of Google, never to be heard from again. Is this normal? And is there any way in which I can prolong this effect? Thank you!
Not really anyway to prolong the effect except wait... this is usual google behaviour for new pages while it works out where to rank the new pages. I find new pages appear for a few days... then often disappear completely (or rank wayyyy down) and then stablise into what will be a realistic position after a period of time. That period of time seems to vary and can be anything from a few weeks to a few months... I often find pages that are closely related to existing content on the site return very quickly in the SERPs but new pages which are on new subject matter take longer. In the worst case I created a brand new section on one of my sites and the pages did their usual disappearing act after a few days. 3 or 4 months later they still hadn't reappeared and I gave up on it being as it was experimental anyway. About 7 or 8 months later I suddenly came accross them, and all pretty highly ranked for their target terms!
The first post is correct, but there is something else to consider and that is how you blog is set up. If you have a link from your homepage to the blog post it may help with your rankings. And then as new posts take over, does the old post links drop off your homepage? If so, you may have lost a bit of link value. Mark
Well, my last five posts are always on display on the main page, and the rest can be visited through the archives. Indeed, I do lose some link value there, but I can't keep links to all my blog posts on my main page, can I? It would only clutter the main page.
Make sure that scrapers have not taken your content. You may have been dropped for duplicate content issues. Google rep Matt Cutts stated last week that Each page of content should be linked to ONE URL, and that within a website, if the same content is found twice it's frowned up.
you may consider the domain age as one of the factors in SERP ranking but don't rely on it too much...providing unique content for the site and SEO performance is where you must focus on.
yeah right, But Age does really matter on SEO Like Authority sites... If you really want to prove it, try to target the same keyword on your 2 different age of sites.
