If you have a budget for one or the other, focus first on creating the best widget you can produce. Then, spend time, if necessary, spreading the word and start building the credibility you need to gain followers and search results. Cultivate your online presence off-site. Your social media presence, your Facebook business page, your reviews on Yelp, and even your answers to industry questions on Quora are all part of your company's "brand reputation."
And Google also uses that reputation in its thailand telemarketing data algorithm. Therefore, the more effort you put into creating and nurturing an online community around your product, the better. Guest posting is not dead. What is dead is publishing to get links. Find influential writers, thinkers, CEOs, and bloggers in your industry and cultivate relationships. Mind you, we didn't say "influencers" or "spam them with guest post requests." Start small, comment on posts that resonate, retweet a relevant upcoming event that your followers might like, and participate in the comments on your blog.
Over time, you can bring the right conversations to text messages and eventually send them an email to share your great idea for a post that you know their readers will enjoy as much as yours. Mentions matter name on the Internet, even if it is not an active hyperlink, Google notices. The higher the authority of the domain in which the mention occurs, the better. So even if it's just someone on Facebook telling their friends about your widget, it's gold for your SEO.
