Your website should be mobile friendly now a da nowadays everything is going for mobile only.Everyone is using mobile so many people go and check in mobile you need to make a mobile friendly URL for your Website.You need to check in Mobile Friendly test about the status of your website.
Use permalink Structure that has keywords
Use an URL which has the text and your keywords included. If your domain name is nice and short and you use short, yet descriptive category names, you can easily include a category in your permalink structure which can benefit your website, but beware: if you end up with a lengthy slug and category name, it will make sharing the URL more difficult and won’t have much added value in Google.
If numbers are included in the Url then it is bad SEO and it results we will not get.
Use Canonical URL’s:
Sometimes Dynamic pages automatically create duplicate content, to avoid this we can use canonical URL. The announcement from Yahoo!, Live & Google that they will be supporting a new “canonical URL tag” to help webmasters and site owners eliminate self-created duplicate content in the index is, in my opinion, the biggest change to SEO best practices since the emergence of Sitemaps. It’s rare that we cover search engine announcements or “news items” here on SEOmoz, as this blog is devoted more towards tactics than breaking headlines, but this certainly demands attention and requires quick education.
Use Keywords for Images:
When we upload any image then we need to add ALT text then it will also help in search results. You include images in your articles to get people to read your text. Well-chosen images also strengthen your message. You shouldn’t forget to give those images good alt attributes: alt tags and title tags strengthen the message towards search engine spiders and improve the accessibility of your website. In this post, I’ll explain all about alt tags and title tags and why you should optimize those.
Note: the term “alt tag” is a commonly used abbreviation of what’s actually an alt attribute on an IMG tag. For any image on your site, the alt tag should describe what’s on it. Screen readers for the blind and visually impaired will read out this text and thus make your image accessible.
When you write an URL use dashes not underscores because google has already been clearly explained in the algorithm that it will not accept underscores only dashes we can use. Hyphens do not define your SEO rankings. It all depends on the traffic coming to your website, where you should have quality content, which can feed customer knowledge.
