Websites are not solitary islands in the sea of the World Wide Web, as much as you are not a solitary figure with no connection to the rest of humanity. Society and technology are constantly changing, so make sure that you are always on top of recent developments so that your websites still fit in the modern world.
Do your homework before you start up a new website. You might have designed killer websites a few years ago, but if you just replicated that now, would you have room for the social media buttons and apps that are everywhere? Do you even know how to put those up? Know what is current for websites and roll with it.
You need to check out other websites to know what current expectations, features and looks are. However, do not copy cat other sites. This can be fine for a starting template, but you need to drop the parts you do not like and take every opportunity you get to make changes and improvements that reflect your own taste and style.
There are millions of blogs out there, but only a few get loyal readers. Which ones are these? The ones with regular content that is both interesting and valuable. Never start a blog on a topic that you are not knowledgeable about. Readers can discern very quickly if you are authoritative on what you write about.
Make sure that your visitors are able to converse with you. This can be done of course through a contact us or comments page on the website, but you are more likely to get discussion going on about what people do and do not like about your website through social media pages for your website. You can even add a free forum to most websites these days.
If you want a truly successful website that gets traffic, do not turn your nose up at search engine optimization. It pays off to find keywords for niche markets that are not well populated, and even just a little article marketing can net you some good search engine result page results. If it is traffic you want, find an unclaimed corner of a busy intersection. Gas station owners understand this.
For interesting content, look offline for sources. Anything that gets posted online that is at all interesting goes viral or shared excessively through social media. Text content is copied, duplicated, rewritten and spun ad nauseum. Get offline as much as you can and live a real world life that is full and rich. You will find ideas for content constantly that no one else provides.
Do routinely visit the websites of your competition. Know what they are doing. Your choices here are twofold. You can either do what they are doing better, or you can do things differently. Try both to find the most odds of success.
Avoid doing what everyone else is doing online. Be innovative and fresh so that you can stand out from the crowd and be an interesting corner of the Internet.
