A reader at the Point Stone blog left a comment asking, "Are we talking about SEO techniques" These are experience or take for granted or have theoretical support? ”

Talk a little bit about your personal opinion.

Strictly speaking, if it is to ask the true theoretical basis, it is not.

SEO Research object is not the nature or the human society objectively exist something or a phenomenon, SEO research is just a company set up rules. And this rule has no objectivity, they can change to change.

Although the search engine algorithm itself has its theoretical basis, but do SEO people are studying how to fully understand and use this set of algorithms. Search engines can make subjective adjustments to their hundreds of parameters.

It's like we're guessing when a restaurant opens, what's the rationale? Alone。 The time to open the door is the boss's one thing. The boss will naturally have a certain basis, such as the General people are hungry 11 o'clock, it is 10 o'clock to 11 points between the door. What is the theoretical basis for outsiders to speculate on whether it is 10:10 or 10:30?

SEO technology is the same, is in the synthesis of a lot of information under the speculation. The so-called educated guess.

Broadly speaking, we are talking about SEO techniques and techniques of course there is a certain basis, although it is not theoretical basis. It must be pointed out that only a very small part of these is verifiable and that most of the technology may not be proven in the foreseeable future.

So where are the SEO techniques we're talking about? What are the unsubstantiated grounds?

The sporadic information disclosed by the search engine Company

For example, Matt Cutts's blog, the search engine official representatives in the Webmaster World Forum to answer the questions of other members, search engine Company's annual reports, briefing, staff talk.

Google, Baidu, Yahoo and other search engines will have a reference to Webmaster website Production Guide, tell you how easy to be included in the site, which will be punished.

However, most of the information is more general, only 11545.html "> We have a principled understanding." For example, we have always known that there are hundreds of factors in the Google rankings algorithm, in the past few months, people inside the Google speech revealed that there are now more than 200 factors, we know that Google algorithm is in progress. But they don't tell you what these factors are.

Statistics and observation

For a keyword to row in front of the site to do statistics, see what factors will be this keyword or the industry more important. At this time some SEO tools to play a useful role, such as check the keyword density.

These statistics are for specific industries, not the same industry rankings have different requirements.

After the different factors/variables to do the statistics should also consider the whole, can not give a single factor too high weight.

I usually compare the difference between the first 10 pages and the 第90-100个 page.

Experimental

Like the experiment on search engine optimization training, many problems can be seen in the process and results of the experiment. Of course, this experiment is beyond my original thinking, a bit out of control. In general, the real SEO experiment is only for a variable, within the controllable range to do.

For example, the location of the key words in the page ranked exactly what impact, can be uncommon in the key words in two different Web page performance to see. The other two pages are all the same, links, text length, keyword density, and so on, just a keyword in the page header, one at the end of the page.

Read a lot

It's not possible to see for yourself what you are doing, so you need to look at the forums and blogs. I counted the blogs I wanted to see every day, now more than 70, plus 3, 4 forums.

Many SEO experts will share their experience with you, this is a very important source of knowledge.

Common Sense and logic

Although the search engine's specific ranking algorithm we can not know, but we know the fundamental purpose of the search engine, that is to provide users with the best information. Plus some other common sense, sometimes even if there is no other supporting materials, you can know whether a technology is good or bad. In principle, useful information that helps the user is good.

Finally, it is emphasized that all the SEO techniques can find a counter example to prove it is not tenable.
