Six questions about Seo beginners

Someone sent me an email asking him about Seo terms he didn't understand. I am sure that not only does he have questions, but many friends may encounter similar problems.

1. What is. htaccess?

. Htaccess is a configuration file uploaded to your Apache network server (it cannot be uploaded to a Windows Server ). It is a text file that allows you to change the way your webpage works. For example, you can add commands in the. htaccess file to set password protection for some fields of your website. You can also create a typical 404-error redirection or change the website homepage.

You will often hear that Seo uses it to create redirection. For example, if you are re-designing your website and decide to change your URL (for example, because you want to add a new content management system), you can use your URL. the htaccess file sets persistent 301-redirection and updates the previous URLs. I often use my. htaccess files to shorten long URLs (such as those member links), making URLs easier to remember.

Be careful when using the. htaccess file on your website! A small error may paralyze your entire website! Remember, before you upload a new. htaccess file, you must keep the previous one as a backup, just in case (if you often only use one, you should be careful )!

2. What is Kei?

Kei is the abbreviation of keyword inclutiveness index (effective keyword index). It is specially developed for users' wordtracker keyword search software. It can help you measure the degree of competition for keywords, But this is by no means a good method. I suggest not focusing on Kei and looking for other methods to measure the degree of competition for keywords.

3. What is supplemental results?

If the webpage is displayed in supplemental results (append result), Google specifies that this is also the content of their SERPS (search result page. This does not mean that your webpage or website is banned or penalized. Most Web pages are often very similar (or completely copied), and they may appear in the append results. Unless most of your website's web pages appear there, you don't have to worry about too many problems. If this happens, you must identify the cause and correct any problems that may lead to this situation.

4. What is link farm?

Link farm has many definitions, but I like the traditional saying. That is to say, linking a farm is a series of websites that decide to connect to each other. It basically runs through a link page. Every website connected to the farm uploads it to their website.

Every time a new website is added to the farm, it must be added to the link page for everyone to re-upload. However, in recent years, this basic idea has changed a lot.

I just want to say that you should try to keep up with any link skills. Especially for those planning organizations, they require you to link some websites, and these websites cannot recommend you to your target audience.

5. When will PageRank be updated?

I believe that the true PageRank-Google's evaluation of the importance of web pages-is always being updated. On the other hand, the PageRank toolbar is updated every moment. This is why you cannot use the green image you see in the toolbar as a real measurement tool.

6. What is a 3-Way link?

3-Way link is another crazy link technique. It is also a typical technique that spammers considers "you link me, I link back to you" to be ineffective, they have always dreamed of another link technique. With the 3-Way link, When you link people to others, these "Others" will be linked back to your website!
