Fortunately, Google puts more weight on the anchor text of external links anyway. So as long as some of your external links have your target anchors, you’re probably OK with a “Home” button. In fact, I’ve ranked homepages with a “Home” anchor text nav button for some seriously competitive terms. So it’s not a make-or-break ranking signal by any means.
This toolbar is based on the LRT Power*Trust metric that we’ve been using to identify spammy and great links in LinkResearchTools and Link Detox since 2012 and the free browser was just recently launched. It helps you promptly evaluate the power and trustworthiness of a website or page during your web-browsing way exacter than Google PageRank ever did.
You can confer some of your site's reputation to another site when your site links to it. Sometimes users can take advantage of this by adding links to their own site in your comment sections or message boards. Or sometimes you might mention a site in a negative way and don't want to confer any of your reputation upon it. For example, imagine that you're writing a blog post on the topic of comment spamming and you want to call out a site that recently comment spammed your blog. You want to warn others of the site, so you include the link to it in your content; however, you certainly don't want to give the site some of your reputation from your link. This would be a good time to use nofollow.
Some search engines have also reached out to the SEO industry, and are frequent sponsors and guests at SEO conferences, webchats, and seminars. Major search engines provide information and guidelines to help with website optimization. Google has a Sitemaps program to help webmasters learn if Google is having any problems indexing their website and also provides data on Google traffic to the website. Bing Webmaster Tools provides a way for webmasters to submit a sitemap and web feeds, allows users to determine the "crawl rate", and track the web pages index status.
