Well…this question can be a serious factor to your website. In all honesty, nothing is perfect in this world and we all strive to improve things as we go along. The same is our English ability.
I found that once you have designed and developed a cool website, as I have done :), you may stumble into the problem of language impairments or grammar in your website.
If you have this problem, don’t panic, it is not the end of the world! One quick tip is to just share your website to people around you and ask them to spot any errors, spellings, grammars, etc. Audience is always the best judge.
Otherwise, you can use professional proofreading expert which could cost you an arm and a leg.
So, my experience tells me that don’t panic and just keep improving it over time and you will get it right eventually.
