The key is knowing how to identify those mistakes and fix them before they cause too much damage to both traffic levels and the general impression left by the site.
Common Mistakes
Made by otherwise excellent website designers.Not Suitable For Mobile Devices
1) Is your website a beauty on
the computer screen? Not only does your website need to function on a
smart phone or a tablet computer, it needs to look just as good on a
smaller mobile screen as it does on the computer screen.
Spelling And Grammar Mistakes
2) If you want to completely
decimate your professional image, all you need to do is misspell a word
or two. But if you like making a good impression, you'll need to
proofread your content multiple times.
Forgetting Social Media
3) If you fail to link to
Facebook or twitter you're missing an amazing opportunity to connect
with your website's visitors. Currently, Facebook boasts 1.06 billion
active monthly users. Don't let them slip through your fingers.
Lack Of Site Map
4) There's no better way to
frustrate website users than to make navigation difficult. Include a
site map so that all visitors know where to access the information they
need.
Not Testing Before Publishing
5) It's easy to make stupid
mistakes in web code, but unfortunately, such mistakes can prevent your
page from attaining accessibility. Test before you publish-- this will
help you catch mistakes before going live.
Keyword Stuffing
6) It's tempting to stuff your
page with keyword phrases, resist at all costs!. Good keywords are
valuable, they get you to that top-ranking link. Only 8 percent of those
viewers will continue on the click the second link.
Non-Adaptive Images
7) Adaptive images are effective
in cleaning up messy HTML. Better yet, they work well with both mobile
and traditional computer.
