Importance of rankings?
If your site doesn't rank on Google, you don't get the traffic leading to no business/sales. Ranking higher on Google is important as around 90% of search traffic goes to sites that rank on the first page Google SERP. And if your site is ranking on #1 position then you are likely to receive around 30% of search traffic. Thus, Ranking is of utmost importance. Besides, if you rank better, it helps to improve your branding and gives a boost to direct traffic.
Favourite Ranking Strategies?
How a user feels when he visits your site defines the user experience. And user experience is the priority if you want to get your site ranked better in search engines. User experience can be improved by offering a seamless movement of the user from one page to another (i.e. technologically sound site with good site speed, no duplicate in pages, usable content etc.). This means no technical glitches, useful content, and smooth navigation helps in ranking a site better on Google.
Elements to be covered in SEO site audit?
SEO audit must cover all technical aspects of the site. Example, factors which help to improve the crawl budget of the site so that more content can be crawled and ranked, duplicate content issues etc.
Second, how well the interlinking is done with each and every page of the site to make sure that valuable pages are accessible for the users as well as crawlers.
Third, low-hanging fruits and new upcoming content opportunities must be covered as per the latest search and industry trends.
Your Dream Feature not present in current SEO tools?
Most of the SEO tools cover only linking and ranking profile of the site. More focus must be given to crawl issues of the site, internal linking of the site, etc. This means a tool that can do a thorough technical analysis of the site would be a great help for SEOs.
