For branding campaigns, your budget is often not an issue. You may have a fixed budget or your budget may be seemingly limitless. It doesn’t matter, because with this strategy the focus is on position; and in most cases only position #1 will do. This is often the easiest strategy to execute for paid search, but it’s also inefficient. The reality is that bidding into the top position in search results is often a waste of money. Google has gone on the record as saying that conversion rates don’t vary much by position, so in many cases all that the first position buys you in paid search is brand awareness (and vanity).
The errors in technical SEO are often not obvious, and therefore one of the most popular. Mistakes in robots.txt and 404 pages, pagination and canonical URLs, hreflang tags and 301 redirects, http vs https and www vs non www versions: each of them can seriously spoil all efforts to promote the site. One quality SEO website analysis is enough to solve all the main problems in this part forever.
