While attending WordCamp KC 2016, I picked up a few tips, mainly about security and SEO fundamentals.
When creating a password, use at least 12 characters. A simple but long password is more secure than a complex but short password.
Use a password manager such as KeePass or 1Password.
When sending logins to clients or customers, use onetimesecret.com
Use captcha on WordPress login screens.
Ubersuggest.org gives you what people are searching for and meta keyword suggestions.
Meta tags and alt tags are still important.
Cachedpages.com shows you the cache Google has on your website.
Use dnsqueries.com to check domain name health, IP address information and reverse DNS lookup.
Screamingfrog.co.uk/seo-spider allows you to crawl websites’ URLs and fetch key onsite elements to analyze from an SEO perspective.
Use inspyder.com/products/InSite to check any website for spelling mistakes, broken links and SEO problems.
Ahrefs.com tracks your website’s backlinks, keywords, brand mentions and helps you to know what your competitors are doing.
Use webpagetest.org to test your website performance and speed.
