Why do we site keywords ranking is unstable?

Our website is a B2B trade stand, industry has been established for more than two years, have always been more stable, but recent, keywords up a few, but not always too unstable ranking, excuse me this what is the row?

 

You make no sense. Perhaps learn English first?

 

There are lot of competation.

 

That may be because of google dance or something. It is nothing but the fluctuation in search position. Keep proper and ethical SEO techniques. You will attain a good search engine position.

 

aælways the new competator try to take your position in search pages, and you should try more SEO and more backlink

 

Yes I agree with help desk.
Try to get more do follow back links as possible.

 

This is very usual when your site is :

1. New sites (new domain)
2. Few backlinks.
3. Low PR usually 0 or 1.

To resolve it you should start a linkk building campain but only with sites related to your site niche and authority sites that means good PR 5 or more ... remember natural links not links on the links.html page

Hope it help
