Google informs the public that they are going to inform the public on monthly basis about their algorithm information that has been hidden for a long time. This is what Google Search Blog says about the recent search algorithm changes. I have made my observation and comments after each changes.
Related query results refinements: Sometimes we fetch results for queries that are similar to the actual search you type. This change makes it less likely that these results will rank highly if the original query had a rare word that was dropped in the alternate query. For example, if you are searching for [rare red widgets], you might not be as interested in a page that only mentions “red widgets.”
Above mentioned Google algorithm changes only shows that we need to use other keywords variation from our main keywords. So in our link building it is better to use different variation of keywords in our anchor text.
More comprehensive indexing: This change makes more long-tail documents available in our index, so they are more likely to rank for relevant queries.
Long tail keywords have always been more targeted than short keywords. Remember that when buyer searches for something in the internet, most of the time they use specified specification for their search.
New “parked domain” classifier: This is a new algorithm for automatically detecting parked domains. Parked domains are placeholder sites that are seldom useful and often filled with ads. They typically don’t have valuable content for our users, so in most cases we prefer not to show them.
So this is the death of earning big bucks from domain parking. It will be better to buy articles and post it in your domain and let it stay there to earn a passive income. A domain owner can use BlogSpot blogs if no hosting is available.
More autocomplete predictions: With autocomplete, we try to strike a balance between coming up with flexible predictions and remaining true to your intentions. This change makes our prediction algorithm a little more flexible for certain queries, without losing your original intention.
Therefore using of keywords synonyms is also important and may also show up in the search results.
Fresher and more complete blog search results: We made a change to our blog search index to get coverage that is both fresher and more comprehensive.
This has been discussed in my previous post about fresh results.
Original content: We added new signals to help us make better predictions about which of two similar web pages is the original one.
This is good for those article owners that are really spending time for their article. I always discourage scraping an article since it will do harm to a blog or web page in the future.
Live results for Major League Soccer and the Canadian Football League: This change displays the latest scores & schedules from these leagues along with quick access to game recaps and box scores.
It only means a tough competition in the SERP for Sports Blog.
Image result freshness: We made a change to how we determine image freshness for news queries. This will help us find the freshest images more often.
This is good changes since most of the time the image that shows in the SERP is irrelevant to the keywords that are being used in Image search. This is just my observation.
Layout on tablets: We made some minor color and layout changes to improve usability on tablet devices.
Well this is good for tablet users.
Top result selection code rewrite: This code handles extra processing on the top set of results. For example, it ensures that we don’t show too many results from one site (“host crowding”). We rewrote the code to make it easier to understand, simpler to maintain and more flexible for future extensions.
So will in not see results with the same domain occupying the top 4 spot in the SERP?
Above mentioned changes says only one thing, Google now loves fresh information to appear on the SERP. This is good for news sites and blogs. If this changes continues, those who owns statics site needs to make their own blog too, to stay on top. It will also mean new opportunity for content writers.
