I keep changing my keyword every day. Is this a good move or will i get banned for doing it? What about my site indexing or page ranking? Will it be affected if i keep on changing my keyword, description, H1 tags and so on on the main page on a daily or monthly basis?
yeah dont change your keyword.. Find the best keyword then add content to your site with those keywords end it... Upload articles to your site that have your keywords in it.. And also write articles that have your keywords.
It will not get you banned but you will not be able to get ranked high if you continue this practice. Stick with 3 keywords and optimize your page according to that. And then get a lot of backlinks with different anchors, keeping focus on those keywords. You will see the ranking.
what is the benefit of changing the keywords? Do other seo stuff on getting position on those keywords in spite of changing them.
Don't do that. How would you get a better rankings if you're always changing your keywords? Pick the best keywords that you want to target then optimized your site using your targeted keywords.
everyday?? well, if you are working daily on it - why change it everyday, you should be adding one new keyword daily
This is quite original technique , but as said above - probably not much profitable. Don't play with keywords. Make good site, with valuable content which is about your destination keywords.
if you change your keyword everyday what is your purpose? and you don't have a goal if you change your targeted keyword everyday.
