My site donot index keywords it used to index
 

Hello,

My website does not index some keywords it used to index. I really don't understand why?

It used to index 2 keywords on the first page on Google, now it didn't index them anymore.

What should I do to get these 2 keywords indexed again?

Thanks.

Use some good SEO concepts to begin indexing again. Using quality keywords will be good.

Some keyword research may give you an idea what is wrong. If your keywords don't get searched for, find better ones that actually get traffic. Try starting with long tailed keywords that get some traffic but don't choose the ones with the most searches because the deep pocket advertisors will have them cornered.

Use some good seo tools.

Thanks to all of you guys for sharing such a very useful information.
