1. Go for domian name generator first.
There are many domain online domain name generator which generate domain name if you input some keywords on which you need domain. So the domain name generator shows you many combination of available domain.
2. Must define your blog topic.
I have seen many people who start for other things and end up writing other things. I bet you have also seen some website whose domain name have other meaning the article you read is not related to that. And thus leaving bad impact on reader. For example say you started the website to showcase wordpress theme but you end up writing about wordpress tutorial.
3. Easy to Remember.
Choose domain name which is easy to remember. Once read or told, the domain must not seem too difficult to remember. For that you must use two general and combine. But such domains are not easily available.
4. Avoid hyphen and number.
Don’t use number or hyphen in domain name. That is not a good practice. Because we think its easy to remember like tips2use.com, so using 2 instead of to only because the name is not available is not good thing.
5. Try to choose rhyme
The words like scoopwhoop or scrapwrap which have rhyme does a great impact on reader and one who hear the word.
If you tell people my word of mouth then they catch it easily and are high chances to visit by hearing like this. This are easy to remember and also attractive to hear and see.
Search for such availability of domain.
6. Have meaning
It is not necessary but if the domain name have some meaning then its good. Have you know any popular blog or website which you follow. You will see that the domain name have great meaning which clearly define their niche and all the above points I mentioned.
So try to choose a proper keywords combination which have certain meaning or nearly a meaning to your niche.
7. Think of Search Engine
If you are very centric about keywords and want to use the combination of known keywords only, then keep Search Engine in mind.
8. Indulge Creativity.
All the keywords, niche and eary to remember name are good but if you become little creative while selection then it will be add on for your name.
