01 The new station is better than the old station



There are so many websites on the market , How search engines find a site ? Let the crawler know this site first , At first, the crawler might do basic screening , The initial performance of some stations is not Big good , So there's not so much time invested in it .

1、 New station : Let Baidu know , New station to do some outside the chain of exchange to be found , You can also use the initiative to submit to Baidu webmaster platform to find the website .

Old station : If the old site was to maintain a better , History behaves well , That's relative to the new station , This old site will be better .

2、 Keep the content of the home page updated , Continue to optimize , The visual experience for users should be simple and clear , The theme is clear , No other complicated information , All in all, it brings users a variety of good experiences .

3、 The structure of the site should be clear , The content has a clear hierarchical logic , Home page > Catalog > Further catalog > Content details page > Internal chain back to other levels , Form a tree structure , And the reaction is URL Structurally .

4、 You don't want negative reviews , Be prepared in advance , Clean up and limit the content , The content of the dead chain should be correct 404, Avoid spiders coming to your site , Waste too much time and traffic on this kind of worthless content browsing , Grab information that's not good for the website .

5、 Other experience details should be carefully maintained , Avoid templated content , It's directly copied from other websites , Borrowing other people's information , Search engines will also macro judge good and bad .

Don't affect users' access to content , Don't go too fast for traffic improvement , In this way, there may be behavior of cheating the search engine .

02 Content pit



About content creation , How to start around your own needs ?

The phenomenon : The demand for the head is crowded , Uneven traffic distribution , Traffic will be allocated to large sites with long history ; The quality of medium and long tail search content is low or even bad , The content supply is insufficient .

Suggest : You can choose to do a little niche domain and content output , The more refined and focused the field is , The better the search ranking .

Relatively unpopular areas : Local life 、 government affairs 、 manufacturing 、 sports 、 History, etc .

Relatively unpopular areas revolve around what they produce , The value of traffic is not bad .

03 Not recommended site building behavior



1、 If the website structure is complex , Hierarchical logic is fragmented , It's hard for spiders to grasp layer by layer , This situation is generally for new sites . If the site has been maintained for a period of time , When the structure is clear , There will be less attention in this area .

2、 It wasn't long since the website was set up , In order to get the amount of grab, do the content crazily , The quality of the product is biased , It's just the opposite , Because Baidu judges when this site is good or bad , It's based on the user's feedback behavior , use sb.'s judgement , If it's hard to get attention , When you don't pay attention to your comprehensive quality , The result is counterproductive .

3、 Use templates from other websites or a large number of common templates to build websites , This will generally appear in the station group behavior , Stations usually use templating , Build lots of sites , There is a risk of being hit by the algorithm . You should build a special style of your website , It gets more attention .

4、 In order to increase the relevance of content , Make up relevant hot words in the title or text . It's like telling search engines what you're very relevant to , But it's not really relevant , This kind of behavior is also not recommended , Once found , The possibility of being abandoned by search engines is great .

5、 Deliberately increasing the length of the content 、 Page turning . For example, the knowledge reserve of an article can only support 400 word , But in order to increase the content, it is hard to add 2000 word , This is meaningless behavior , Pages with too much content , Or add some meaningless page turning , It's not helpful for the collection .

6、 The field is not concentrated , The content is scattered . A website seems to know everything and do everything , But in fact, nothing is good , There's not a single area of focus , This is not just in Baidu , It's also unpopular on other platforms .

7、 Advertising interferes with user behavior in the browsing process , Not conducive to the value of the site judgment .

When the content is made , I'm not sure if the quality of the content is good for inclusion , It can be done by 5118 Of 「 Originality test 」 function , Quickly check the originality of the article , Determine whether the article can be used in the website , Avoid homogenizing content , Risk aversion .
