If we work for more than 2 keywords for the same page at the same time, then how will is effect on the ranking ?
As suggested by bestforyou786, if you are just starting out then it would be quite hard to concentrate on more then 1 keywords. Not it also depends on the strategies that you are using. If you are just following forum sigs and blog commenting then its really not going to work out if you are aspiring to provide professional services. If you really want to target 2+ keywords, you should be working more on social media, press releases, because those are the places where you can have multiple things worked on at the same time.
yes one keyword at a time because doing seo to a site is a hard work .. and it takes months to get your site to the top of GOOGLE
yeah you might want to avoid doing multiple keyword for a single page. spread it out, the more pages the better anyway.
I we create links for or a page then all keyword that are available on the page and their ranking depends on the competition of that keyword
it depends if that keywords existing on tha page then you can target it. otherwise you can target relevant page on which keyword is placed.
you can use google keyword selection tools https://adwords.google.com/o/Target...000&ideaRequestType=KEYWORD_IDEAS#search.none
Concentrating on 1 keyword at one time is good to get a desired output as SEO is a long-term solution and it takes long time, may be few months or a year too.
If you are using the same page targeting two keywords, I would suggest you to promote it by having one keyword as primary and use an other keyword simultaneously as secondary. i.e when promoting your website with a certain keyword which will be used as an anchor text / title and use the rest as tags and do for the second keyword wise versa.If you do so your both keywords will rank in good position
