One piece of software any optimizer should love is Firefox. Now some may possibly say 'Why Firefox, it is only a visitor'? Yes, it is a visitor, but the one that supports a big variety of extensions, some of them very useful for search engine optimization. Be taught further on this affiliated article by browsing to address. Therefore let us see what those plug-ins are: 1. SEOpen ( https://addons.mozilla.org/firefox/570/ ): this really is one of the best and most used Firefox seo jacks, and has many methods which make it a favorite of mine. If you are interested in literature, you will probably need to read about plus.google.com/+tylercollinsseo. So let us see what it may do: * in Google it may examine for: backlinks, found pages, associated pages, cache and PageRank. * in Yahoo and MSN: backlinks and indexed pages. * for Alexa: introduction, traffic details, backlinks and related sites. * keyword thickness of the very most used words on the site. * DMOZ checker: see if the site is included in the directory. * check for robots.txt. * validator to test your page for problems the validator is used by it from www.w3.org). There are other things, but these are the main. 2. SEO Links ( http://www.webmasterbrain.com/seo-tools/firefox-extensions/seo-links/ ) is another expansion I use daily. When the expansion si effective and you hover over a link a tooltip will appear that will show you Yahoo, MSN, and Google link popularity and rating data for the URL and anchor text set. When you are simply checking this can be annoying, but you can simply de-activate it with a right-click! This may be very easily used to check your se rankings for a particular page, and here is how: jot down a list with all the keywords and keyphrases you want to rank for, and then link these words or phrases towards the website pages associated with them! Now each time you need to check always your ranks trigger the Search Engine Optimization Links extension and float on the links -- you will see where your pages have been in Google, Yahoo and MSN. 3. Don't waste anymore of one's valuable screen property merely to find out what your PageRank and AlexaRank is! SearchStatus ( https://addons.mozilla.org/firefox/321/ ) could sit anyplace you want (I keep it in the status bar) and you'll have the important info at a glance. But this small device may do much more than that: * it shows what metatags a niche site has * checks for backlinks and indexed pages in Google, Yahoo and MSN * it shows the file * key-word thickness report function * and best of all: the spotlight 'nofollow' links will show you what links will be followed closely by search engine spiders -- very useful when you want to submit your site to a directory and don't know if it will matter from a seo perception.
