Search engines often see this as a platform of quality content and hence pay close attention to the volume of such social signals.

Meta tags mean those snippets of text or “metadata” that describe a webpage’s content. Meta tags include certain other things within them like the title tag, meta description, and keywords of a page.

Meta tags are not visible on the page but are visible within the HTML code, which can be seen by search engines only.

As per some experts in the field of SEO, meta tags do not have as much importance anymore since Google has discontinued the use of meta tags in its page rankings. Though, meta tags do provide crucial information to users and the search engine about the web page. By providing this additional information about your website, Meta tags may improve the click-through rate of the web page which plays a significant role in improving a page’s ranking

Hence, meta tags always play an important in SEO, at least indirectly if not directly.

The quality that your URL structure possesses does have an important effect on the ranking of your page ranking and on the SEO efforts that you have made. One of the significant requirements of URL structures is that they should be short, easily readable, and capable of identifying at a glance where the user is going. The title of the page should also be concise and capable of supporting the contention of the page. A study conducted by Quicksprout shows that URLs containing 35 to 40 characters have dominated the listings of search engines.

Q10. Does being mobile-friendly improve SEO?

Well, Yes and no. Being mobile-friendly can and can not improve SEO. Since there have been certain changes in Google’s algorithm, Google has started considering the mobile-friendliness of a website as one of the key points while ranking them. However, this applies only to search done on mobile devices and does not affect the search listings on desktops or laptops.

Though, with an increase in the number of mobile users, it is considered wise to optimize your web pages for mobile devices to obtain better results.
