Having a different description meta tag for each page helps both users and Google, especially in searches where users may bring up multiple pages on your domain (for example, searches using the site: operator). If your site has thousands or even millions of pages, hand-crafting description meta tags probably isn't feasible. In this case, you could automatically generate description meta tags based on each page's content.
Early versions of search algorithms relied on webmaster-provided information such as the keyword meta tag or index files in engines like ALIWEB. Meta tags provide a guide to each page's content. Using metadata to index pages was found to be less than reliable, however, because the webmaster's choice of keywords in the meta tag could potentially be an inaccurate representation of the site's actual content. Inaccurate, incomplete, and inconsistent data in meta tags could and did cause pages to rank for irrelevant searches.[10][dubious – discuss] Web content providers also manipulated some attributes within the HTML source of a page in an attempt to rank well in search engines.[11] By 1997, search engine designers recognized that webmasters were making efforts to rank well in their search engine, and that some webmasters were even manipulating their rankings in search results by stuffing pages with excessive or irrelevant keywords. Early search engines, such as Altavista and Infoseek, adjusted their algorithms to prevent webmasters from manipulating rankings.[12]
Black hat SEO involves techniques such as paying to post links to a website on link farms, stuffing the metadata with nonrelated keywords, and using text that is invisible to readers to attract search engines. These and many other black hat SEO tactics may boost traffic, but search engines frown on the use of such measures. Search engines may punish sites that employ these methods by reducing their page rank or delisting them from search results.
I’ve always been one to create great content, but now I see it may not necessarily be the right content. Can Share Triggers work for all niches including things like plumbing companies, computer repair, maybe even handy men that have a website for their business? I would say I’m estimating half the views a month as I should. Hopefully some of these strategies will help.
I first heard you talk about your techniques in Pat Flynn’s podcast. Must admit, I’ve been lurking a little ever since…not sure if I wanted to jump into these exercises or just dance around the edges. The clever and interesting angles you describe here took me all afternoon to get through and wrap my brain around. It’s a TON of information. I can’t believe this is free for us to devour! Thank you!! Talk about positioning yourself as THE expert! Deep bow.
Each organic search engine ranking places emphasis on variable factors such as the design and layout, keyword density and the number of relevant sites linking to it. Search engines constantly update and refine their ranking algorithms in order to index the most relevant sites. Other variables that have an impact on search engine placement include the following:
Like you I am a scientist and like you did in the past, I am currently working on translating great scientific literature into tips. In my case it’s child development research into play tips for parents. I can already see that the outcome of my experiment is going to be the same as yours. Great content but who cares. I hadn’t even thought about my key influences. I know some important ones, but don’t see how they would share my content. I thought I was writing content for my potential customers. Is your SEO that works course the same as the content that gets results course? Sorry if I sound a bit dim asking that question.
It’s an awesome post which I like the most and commenting here for the first time. I’m Abhishek founder of CouponMaal want to know more like you’ve said above in the points relaunch your old posts. Here I want to know is there any difference between changing the date, time and year while we’re relaunching old post OR we should relaunch the old post with the previous date, time and year. I mean it matters or not.

Website owners recognized the value of a high ranking and visibility in search engine results,[6] creating an opportunity for both white hat and black hat SEO practitioners. According to industry analyst Danny Sullivan, the phrase "search engine optimization" probably came into use in 1997. Sullivan credits Bruce Clay as one of the first people to popularize the term.[7] On May 2, 2007,[8] Jason Gambert attempted to trademark the term SEO by convincing the Trademark Office in Arizona[9] that SEO is a "process" involving manipulation of keywords and not a "marketing service."
