I have a website and I am trying to promote it. I know a bit about SEO. Wat will I do I am working with some keywords will I have to change them after sumtime or just continue with it.
What are things have you done initially for your site? Have you tried checking this Google SEO guide: http://www.google.com/webmasters/docs/search-engine-optimization-starter-guide.pdf Please let us know more info about your website and the steps that you did for the campaign. But I suggest that you should take an overall initial analyzation of your website.
If the keywords are likely to bring you traffic, then you need not change them. You could obviously work on bringing in additional traffic by working on other keywords.
For that first of all you have to get more knowledge about SEO, then after you have to promote your site and this will really benefit for you & your site.
You can do the following: 1. On-Page Optimization - it deals with the proper use of meta tags, title tags, alt-tags (when describing images), h1/h2 tags, description and keywords (you can use some of the keyword tools to help you).. 2. Off-Page Optimization - it deals with building links.. [ex. blog commenting, directory submissions, social bookmarking, link exchange, press release, classified ads, article submissions, forum posting]
why change them? add more to the list if you've achieved your targets with current ones. Do you know how to conduct a proper keyword research?
Try to follow everything that they say here, learn it and know what's its use. I think when you have it then you're on your way of making good SEO.
of course at first you need to use your less competitive keywords to get easily rank on search engine and after that you are shifting gradually to your more competitive keywords.
if you are doing good with, why change it. But if that keyword didn't give you good traffics search of other keywords.
You have to choose relevant keywords according to your websites term and focus on them. If you know SEO then you can easily get good SERP. best of Luck
