A web page's "URL" is the actual address of that page. The WideRange Galleries software enables you to enter your own customized URL address for every page.
For example, instead of having a meaningless database-generated address such as "https://yoursite.com/photo/1234/", your pages can have readable, relevant addresses such as "https://yoursite.com/photo/moonrise-over-denver/".
URLs and SEO
Keep in mind that Google has actually stated publicly that they do not factor URL addresses into their search indexing and ranking
In reality the benefit of readable URLs is mainly for people and click-thru rates. People are more likely to click a link if they can quickly read and identify what the link is about at a glance.
Therefore the best URLs are short and succinct, and it doesn’t help to stuff them with keywords (a tactic that is targeted to robots, not humans). In fact that could actually be counterproductive if people see a gigantic keyword-stuffed link — it’s too long to quickly read, and it may just look spammy.
Avoid Changing URLs
**IMPORTANT** You should AVOID changing the page URL after you've saved it (after the website has been launched). This is because the URL is the page address, and if you change it you will lose any external links or search engine rankings that you may have already earned for that page!
