3, keywords regardless of difficulty, no matter how popular keywords, as long as you want to do, you can enter the top three or even.

Disadvantages:

1, if the price is high and the competition is fierce, the unit price can reach several yuan or even tens of yuan, and it will be thousands or even tens of thousands of yuan in a month.

If you do it for a long time, it will cost so much money.

Employee salary (the monthly salary of the person in charge in Wuhan is around 2000-4000).

4, the independence of the engine, each engine is independent, after you bid in Baidu, Google will not rank, nor will Yahoo.

There will be rankings, and if you want all engines to have rankings, you have to spend several times the promotion fee.

5, poor stability, once the price of others is higher than yours, then you will fall behind; Once the daily budget in your account is used up, then you

The ranking will disappear immediately.

Courses.

Second, the advantages and disadvantages of seo.

Advantages:

1, the price is low, and the cost of website optimization to maintain a one-year ranking may only be the cost of bidding for one or two months, which is much cheaper than bidding.

2. The management is simple, and the enterprise does not need special management. Everything is maintained by the website optimization service provider for you. What enterprises have to do is to observe the rankings irregularly.

Whether the location is stable can save you the cost of hiring professionals to manage it for you.

3. The biggest advantage of engine take-all and website optimization is that there is no engine independence. Even if only Baidu optimization is required, the result is also

Visitors.

4. Don't worry about malicious clicks. The effect we do is natural ranking, and we won't pay per click, no matter how your competitors click, we won't give it.

You wasted a penny.

5. Strong stability. Websites ranked by regular website optimization methods are very stable as long as they are properly maintained, and they have been positioned for several years.

Time may not change.

Disadvantages:

1, the effect is slow, and the ranking cannot be obtained through website optimization. Words with general difficulty take about 2-3 months. If the words are more difficult,

It takes 4-5 months or even longer. It is suggested that enterprises can optimize their websites in the off-season, and the ranking in the peak season is basically stable.

2, the uncertainty of ranking rules, because search engines have different rules for ranking, it is possible that a search engine will enter the ranking rules one day.

After the change, it may change the original ranking position at that time. This is a very normal phenomenon. At that time, we will learn as quickly as possible.

The new rules will restore the ranking of the website.

3. It is very difficult to distinguish difficult and competitive keywords, such as mobile phones and MP3 players. It is very difficult to optimize the ranking, which requires non-.

After a long time, the cost will be high, and words that are too difficult are not suitable for optimization.

4. The number of keywords is limited, and only one keyword is recommended for website optimization, with a maximum of 3-4 keywords, of which 1-2 is the keyword and the rest.

1-2 is a participle, which can't achieve the bidding ranking effect you want.

5. The ranking position is behind the bidding ranking. This is determined by Baidu's rules. The natural ranking position can only be behind the bidding ranking website.

If the first page is full of bidding rankings, natural rankings can only appear on the second page. At present, this situation only exists in Baidu.

Comparing the above advantages and disadvantages, the overall effect of website optimization is far stronger than bidding ranking, and the price is also lower than bidding ranking.

On several occasions, those companies that claimed that "it's so expensive, it's better to rank by bidding" only competed with Baidu, which has used the optimized price of the website to control daily costs.

Compared with the price, they didn't consider that the optimized website would improve the ranking in all engines, and also ignored the bidding of other search engines.

The illusion caused by consumption cost.
