URLs being basic to SEO, they are an important factor for page ranks. URL optimization appears simple but is not really so.
Begin with a TLD that increases trust, which means a .com domain and not .pro. TLD does not directly affect rankings.
Since online security is very important, choose HTTPS rather than HTTP. Encryption for HTTPS refers to security. Cybercrime has increased enormously. HTTPS increases ranking with an SSL certificate. Sensitive customer information and financial deals online require the SSL certificate that may be bought according to the duration required. Namecheap is one of the SSL providers.
After the SSL certificate is installed, the site is updated to use HTTPS.
SEO friendly URLs-Length
Regarding length, the shorter URLs are better. Those rank higher than the long ones. Google prepared a graph to show that the first ranking URL has about 50 characters. Between 50 and 60 seems to be good. Longer URLs like 80 would have a negative ranking.
Three to five words should be good enough to communicate simple, essential meanings in the URL.
The URL should be user-friendly and relate to the SEO, communicating meanings well to humans and search engines. Consider the readability scale. Make it short, sharp and easy to understand. Longer URLs get complicated. Be simple and clear, understood at a glance, aimed at humans.
Prefer Hyphens to Underscores
Fill up spaces between words with either of these, hyphens being better, according to Google.
Uppercase letters could lead to Error 404 and redirects, lowercase is always best.
Stop words are fillers like a, an, or, but, that connect essential words. These words carry no importance and do not contribute to ranking. Better not use them. Stop words will only lengthen URLs. If a stop word helps readability, include it.
Use Safe Characters
Safe characters would be better rather than the unsafe ones like symbols that create browser problems and usability issues.
Two Folders Per URL
Slashes between text in URLs indicate folders and less is better. One or two would be simple and best. Search engines understand them better.
Include One OR Two Keywords
Considering their importance, do you use keywords in URLs? A little advantage comes from using keywords and helps users besides serving as anchor text. People understand subjects better. Yet, avoid stuffing keywords. One or two keywords are fine and no more, best located at the beginning of the URL.
Don’t Repeat Keywords
Avoid repetitions of keywords or words in URLs. That would be regarded as malpractice and look like spam.
Reiterating in conclusion
URL optimization is never so simple when you cater to humans and search engines. TLD and SSL ensure site security. Limit words and characters and make it readable by humans. Format well for browsers. Pay attention to keywords. Common sense and taking it one by one makes it fairly simple. Short and sweet, easy to read.
