Sometimes I think: professional site and portal between what kind of SEO in the main advantage? A few days ago did a tourist site data analysis, so there is this article analysis.
De Xuan that the professional site with the portal station the biggest advantage is the more value of the site's own optimization, the relative majority of the professional station is not a portal station daily average access traffic is high. The next PK showdown will explain exactly what happened:
PK Duel One: Professional travel website TOP10 Analysis
This analysis is in the Alexa ranked top 200,000 professional travel website TOP10, the following figure:
Analysis:
1), through the figure of the impact of the site ranking factors are: PR value, Baidu weight, the site outside the chain, domain name registration time several, especially the domain name registration time to a site to bring a high weight;
2, in the higher weight of the site to its daily average visit is also relatively high. Google's high PR value of the site in the exchange of friends in the chain will have more advantages, Baidu weight (currently only for reference) the weight of the site's average daily traffic can not be ignored;
3, from the following map can be seen the advantages of foreign websites are focused on optimizing the Google search engine, more value the value of the link output. In addition, the domain name registration time is earlier, not to say that the old domain name must have an advantage. Figure:
PK Duel Two: Portal Tourism channel TOP10 analysis
In the data analysis Phase I was thinking about what the portal site needs to be a reference, in order to reflect the differences with the professional site and compare the rankings between the portal site
So I was in the professional site data Reference standard added an inverse keyword: "tourism" rankings. This makes it easier to see the portal tourism site between the Dragon Tiger hegemony, but also with the professional site for comparative analysis, as shown:
Analysis:
1, from the top of the rankings to see a number of major portal stations are very high.
The sad Tencent did not qualify for the TOP10 list, because Tencent tourist site is using the top-level domain name network. I think if you put it in the level two domain name will definitely be on the list. Wonder is Phoenix Tourist channel PR value unexpectedly is: 0. So from the PR value of the above figure, the portal is not very attached to the channel.
2), portal tourism website pan keyword ranking
From the top of the "travel" Pan keyword rankings, the portal site of the key to the channel's keyword optimization than professional sites have advantages. This is the same as I expected.
3, Domain name registration time highlighted. Major portal tourism sites in the domain name registration time has a great advantage, of which, the registration time for the Chinese network: 1994, Yahoo's registration time: 1995.
4, Baidu weight on the impact of the portal site. From Baidu to the weight of the major sites to see, only two: 1. Other weights are very high, the corresponding flow is also very large.
Paragraph Xuan here to say is that Baidu weight is not the official statistics, but by Third-party service providers love to measure. So, this data is for reference only.
Summary: Through the above professional tourism sites and portal Tourism site PK confirmed my original conclusion: professional sites more value the optimization of the site itself, the portal is not very important to the channel. At the same time, data analysis is also a great help in learning SEO knowledge. Everyone has their own opinion of data analysis, De Xuan welcome everyone to take a brick.
